I've had a waterpump replaced under warranty because it cracked. Might be worthwhile getting it looked at by the dealer. MK6 was really bad for it but I don't think MK7 was trouble free in that respect.
Lower radiator quick disconnect leak
Location Florida USA. If the leak is slow enough, it's evaporating before it even gets outside the housing. Mine went from "max' to about 5mm over 'min' levels in the reservoir over the course of a 5k oil change interval. Zero visible residue anywhere when inspecting everything while on the lift.vw golf radiator leak
Location So Cal. I've heard people say that the new mk7's drop coolant when new then it settles in and doesn't lose that much coolant after that. George Ab Drag Race Newbie. Location Pacific NW.
Unfortunately you are out of the three year bumper to bumper and coolant leak would not be considered covered under powertrain. I have had to top mine off twice in 42, miles and over three years since purchased. Based on the forums, many of us have minor coolant leaks.
If you are not smelling coolant, seeing coolant tough to see with intake manifold in wayand only having to top off once a year or so I would not be concerned. At 60 or 70K miles when I do the intake valve cleaning I will closely inspect the pump and thermostat, but will not replace if I continue to lose at current rate. The second time I do the intake valve cleaning at or K I will likely replace water pump as part of preventative maintenance even if the leak does not get worse.
The Fed Old Guys Rule. Location Florida. Slight leaks can dry and harden and never leak again unless you scrape off the hardened residue. Why wouldn't be covered, as long as it isn't leaking from a hose?
Leaking Lower Coolant Hose at Radiator. Thread starter dlee Start date Jun 1, It drips some even when cold. My first thought was to replace the seal in there. When I put the new seal in, should I put in on the plastic flange at the radiator, or inside the connector that slides on the radiator flange that the lower hose is clamped to? I have tried for about an hour now. I'm wondering if the clip is bad at this point, or I have the seal in the wrong spot. I really appreciate any advice.
Campbellonh Veteran Member. It took me forever to do too. You have to make sure the seal is seated really well, then the clip should go on fine. When I was having trouble, it turned out to be that I had not pushed hard enough to fully seat the seal. It is hard to get at without removing the front grill, but do-able.
Did you clean off the flange surface on the radiator after taking the seal off. Needs to be really clean. Do you mean the seal should be seated at the base of the radiator flange, or inside the connector? It may be easier to seat if you put it inside the connector, which is what I did. There is a slight ledge it should rest against, that you should be able to feel with your fingers.If your vehicle has a history of irregular oil changes, extreme climates, or low RPM driving, condensation and moisture can form in the engine and cause sludge to build up, creating the possibility of a leak.
In addition, the crankcase breather system can also become clogged, preventing the engine from ventilating properly and causing a buildup of pressure. Oil then leaks from the weakest parts of the system. Other parts that are often leak culprits are the valve cover gaskets, camshaft seals and plugs, front and rear crankshaft seals, and cam chain tensioner gasket and seals, and O-ring.
If you see oil covering the filter and cooler, the O-ring is likely the problem. If coolant from your VW is leaking from the water pump, the internal bearing and seals are most likely weak, and there will be a trail of coolant from the pump region down towards the engine. If there is steam blowing from the engine, the coolant leak is likely originating from the coolant flange.
If coolant is visible under the vehicle, the radiator is the most probable culprit. Coolant hoses also often cause coolant leaks, since they can be damaged by oil leaks and age. It is best to address a coolant issue as soon as you can to avoid engine overheating. If there is smoke coming from your vehicle's exhaust, there is likely a coolant leak. In this case, the likely culprit is a faulty head gasket, warped cylinder head or cracked engine block, especially if you notice a burning oil smell while driving.
Another way to tell if there is a coolant leak is to check your oil for a frothy, milky appearance, or for internal leaks, a sweet odor and low coolant reservoir levels. All of these parts should be replaced at the same time. If your timing belt needs replacing, the camshaft and crankshaft sensors will detect an error, and the check engine light will come on. The timing belt may be showing signs of wear, but has not yet snapped, if you hear slapping or scraping noises coming from the engine.
Since the VW cooling system only hold a small amount of coolant, it is important to have your vehicle repaired shortly after it shows signs of overheating. Generally, coolant parts should be replaced every 60, miles to avoid issues. If your vehicle does overheat, their are a few different possibilities for the cause of the problem:. A failing coolant reservoir or radiator can result in pressure issues that prevent coolant from reaching the engine, which then overheats.
The engine fan may need a repair or replacement so that air continues to flow properly through the radiator and prevent the vehicle from overheating at low speeds. A defective thermostat that limits the flow of coolant to the radiator is also an option if your engine is overheating. It may also be necessary to check the coolant temperature sensor. If the reading on the sensor is above degrees, however, there is most likely an issue with your thermostat or water pump.
Suspension concerns ie. Clunking noise while going over bumps, Clicking noise while turning. If you have been hearing squeaking or clicking noises when turning your VW, there is likely a suspension issue caused by faulty ball joints, which absorb shock from up-down movements and rotate with steering wheel movement. Another possible cause of abnormal noises when turning your vehicle is worn out bushings on the control arms, or the hinges that hold the wheels to the frame and connect steering to the wheels.
Also consider the brake pads and rotors, loose screws near the rotors, or the vehicle's springs, if your vehicle is lower on one corner when at idle. At times, there is no need to worry about a maintenance indicator on your VW, like if the light is green signifying something informational such as you're daytime running lights being on.Forums New posts Search forums.

I can tell that I have a leak somewhere but as it's a slow leak it's not too worrying. My only concern is this a common fault with this car or do I have something new? I appreciate any feedback you can give, as I'm reluctant to go straight to the dealer and fork out a possibly high repair bill! Many thanks!
No problem here, going on my third winter. Just it flushed and filled a couple weeks ago too. Good habit to flush and replace coolant every years as it degrades slowly overtime and will slowly eat away at your rad.

It's a trick I have used before to find hard to diagnose pesky little leaks on all of my cars! Location New Zealand.Without the power steering system, your Golf would be very difficult to drive. Most of the weight of the vehicle is absorbed by the power steering system, making it feel much lighter than it really is.
The first thing that you would want to do is look around the power steering hoses for any obvious signs of a leak. The power steering hose will run from the pump to the rack or gear.
The most common place that the hose will leak from where the metal part of the hose meets the rubber. Look for power steering fluid on or below it. It is turned by the serpentine belt attached to the engine. The pump can wear down over time. When it does it can begin to leak power steering fluid under the engine. On some makes and models there will be a power steering cooler.
It will look like a smaller radiator. Fixing the power steering fluid leak in your Golf is a pretty straight forward process.
If there is anything that you would like to add, please feel free to leave a comment below. This is the sound of the pump not having enough power steering fluid to cycle through the steering system.
Modern vehicles are not made to be driven without power steering. Their close ratio steering makes them very hard to operate without power steering. Power Steering Hose The first thing that you would want to do is look around the power steering hoses for any obvious signs of a leak. Rack or Gearbox There are seals in the rack or gear box that can go bad over time and leak.
Cooler On some makes and models there will be a power steering cooler. First, take a look at the power steering lines, they most commonly leak where the metal meets the rubber on the line. Replacing the line will stop the leak. Hoses are cheap. After that, the power steering pump itself would what you would want to take a look at. A leaking power steering pump is easy to identify. Seals in the rack and pinions or steering gear box can and do go bad over time. The leak should leave fluid further back than the power steering pump.The unit itself is expensive to replace, so before you buy a new one, pressure test the cooling system first and verify the location of any leaks.
It will be easier and cheaper to replace a radiator hose or clamp than replacing the whole radiator. Replacing the radiator on the GTI MkV is a fairly involved job that requires removing a lot of components on the car including basically the entire front section. If you take your time and begin by working on a cool car you will be fine. Open the cap of cooling system slowly; turn a conventional coolant cap as far as the first detent and turn a screwed coolant cap approx.
Wear protective gloves, protective clothing and eye protection.
NEVER pour coolant into beverage bottles, cups, etc Someone might accidentally pick that cup up and start to drink. If the coolant in the car is new there is no reason to replace it as long as you drain it into a clean container.
Coolant is expensive and not too great for the environment, so if the coolant in your car is good, try and save it to reuse.
While you may be able to crawl under the car to complete this job I recommend that you safely jack up and support the vehicle.

Please see our article on safely jacking up and supporting your car. Disconnect the ground strap from the battery terminal red arrow and place the cable yellow arrow where it can not accidentally come in contact with the battery while working. For more information please see our article on battery replacement. Large Image Extra-Large Image. You will need to remove the charged air pipe. The charged air pipe and hoses run from the induction system and divert air before it reaches the throttle body red arrow.
This charged air runs through a pipe that is secured by an 8mm bolt blue arrow and T30 Torx green arrow and enters the interior by a quick release fitting yellow arrow. Please see our article on removing the charged air pipe for further assistance. At the front left side of the engine compartment is the air intake.
There are two T20 Torx screws holding this to the airbox cover, red arrow, one shown remove these. Note our project car was missing the upper part of the housing. Remove the two T27 Torx screws from the air diverter red arrows. Note: You do not need to remove the engine cover to perform this job, just get the intake hose to lock carrier out of the way. A great many of these cars have had the engine trays and front side shields removed over the years and not replaced.
If you happen to have a car that still has all the under trays and original hardware here is what you need to do. There are four T25 Torx screws red arrows on each side holding the tray on, remove them and slide the tray back out of the friction clips yellow arrows on the front air dam.
Once the screws are removed slide the tray red arrow back and down. Unclip the wiring connection for the fans on the lower left corner red arrow. You can disconnect the quick release connection red arrow on the lower right radiator hose and separate the hose from the radiator.
Coolant will spill out from both the hose and radiator so be prepared to catch them.Just found out I got a horrible leak on my radiator. I have a golf mk5 sdi. I did use k-seal a couple of years ago but when I changed the timing belt 3 weeks ago my mechanic put new coolant in. So I think that might of been the problem. Question is are they common problem?
My old MK4 model it was an SDI estate hence the late year did spring a very minor leak bottom right corner as you look under the bonnet.
It was k miles The Skoda Octavia I had before also had the same problem but that car had similar miles but was a model. So, k miles forget age is hardly a common fault as things do not last forever. In both instances I put new radiators on and it gave me a chance to also change the coolant.
I do not like a "fix from a can" as your water pump is driven by the cambelt and you can imagine a scenario if the pump gunged up and seized stripping the cambelt of a few teeth With the Golf the front bumper needs to be removed to get to the radiator mounting bolts, its not nearly as bad as it sounds, pipe connections are push fit with a metal horseshoe type clip.
Its a fairly easy job for a competent DIY person. Not at all. Where is it leaking - near the seam where the plastic and metal meet? A little-known fact - G12 actually seals small leaks by itself. I really wouldn't put anything in the coolant system. Speaking of which, which coolant did your mechanic use when he put the new coolant in?
As mentioned, a new radiator is not that expensive. No more than any other car. Using any kind of "sealer" is a patch at best, and does more damage at worst. Answer Save. Favourite answer. Chris Lv 6. What do you think of the answers? You can sign in to give your opinion on the answer.
