VW_Novis Posted May 15, 2007 Report Share Posted May 15, 2007 Hi Guys, Wonder if anyone can help. Last week my STOP ! Check Coolant Level alarm came up, so checked it and it was low. Topped her up and carried on. Four days later - happened again (I do about 80 miles a day). Topped her up, and this cycle continues ..... Removed the cover from the bottom of the engine bay after running her up the road and as from this picyure, you can see roughly where the leak is, but I cannot find it ! The leak is dripping off the front passenger side (Right Hand drive car) axle area. It would appear that the coolant is only dripping on the back part of the cover ? Can anyone help me please !!!!!!!!! VW_Passat_Cover Link to comment Share on other sites More sharing options...
ajnabi Posted May 15, 2007 Report Share Posted May 15, 2007 Hmmm.... I had the exact same problem (2001 Passat 1.9TDi 60K miles)... i.e. coolant disappearing... without any trace on the road, except when taking the belly pan off the car. I highly suspect you have a leaking radiator.... try to examine the radiator ... it's not the easiest thing to see hidden away amongst the fans and the bumper. If I'm not mistaken it's a common problem around those years. Approx. £100 for a new radiator from VW. Plenty on ebay .. but to get the right one requires some skill. But obviously you will have to confirm that is the problem first. Link to comment Share on other sites More sharing options...
mulkbear Posted May 15, 2007 Report Share Posted May 15, 2007 I would put money on it that it is the radiator that is leaking, guarantee it. When they leak the coolant runs along the chassis leg and on to the back under tray. Link to comment Share on other sites More sharing options...
meriafel Posted May 16, 2007 Report Share Posted May 16, 2007 My 2002 Passat, only leaked when hot when it would dump half a litre in one go. Even a dealer four hour pressure check failed to find it. When pressure checked overnight dealer found it exactly same spot as yours. Fortunately under warranty at about 70k. (Had bought back the 3rd year due to excess miles) Link to comment Share on other sites More sharing options...
VW_Novis Posted May 16, 2007 Author Report Share Posted May 16, 2007 Thanx a lot Guys. Is there an easy way to prove this - or does the whole front bumber etc. have to come off ? Link to comment Share on other sites More sharing options...
Eng33 Posted May 16, 2007 Report Share Posted May 16, 2007 Just fixed mine, a 2003 130 Sport TDi, with 86k miles. Radiator leaking from left hand end tank, coolant sensor also failed, so did the whole job in one go. Relatively straight forward to do yourself, cost of genuine parts was around £110 all in (trade).

VW_Novis Posted May 17, 2007 Author Report Share Posted May 17, 2007 Just noticed a damp patch on the carpet in the Passenger Side front compartment - still radiator - or heater matrix ?? Link to comment Share on other sites More sharing options...
Evobaz Posted October 10, 2007 Report Share Posted October 10, 2007 I know this is an old thread but I had a similar leak on my Passat Tdi and it was the water pump. Had the timing belt replaced and they told me the pump was leaking . Pump replaced and leak sorted. Link to comment Share on other sites More sharing options...
cazman Posted June 20, 2009 Report Share Posted June 20, 2009 Hi, I know that this is an old thread but can you tell me what fixed your leaking problem? I changed the radiator, the water pump, did the pressure test and still loosing a lot of coolant. Thanks Link to comment Share on other sites More sharing options...
Bromley Posted June 22, 2009 Report Share Posted June 22, 2009 Personally mate, i'd suggest attaching a bottle below the overflow on the back of the header tank. That way the bottle will either fill when it dumps fluid or you can eliminate, that from your list of possibilities. I've the same leak as described above, and found that during a journey, the coolant was getting hot (temp gauge still at 90°C) pressurising and dumping out the overflow on the bottom of the headertank and draining off the undercar trays as described above. So far a friend of a friend who runs a business specialising in VAG's has said without seeing the car that all symptons i describe point toward headgasket. But since i have noticed that, whereas the top rad pipe is very hot following a journey, the lower one is cold. On discovering this i ran the car with the small return hose to the header disconnected, to see if water was circulating and have found that very little seems to be?, when held at a constant 4000rpm, no water is beeing passed through this hose back into the header tank. As a result of this, i'm going to change the waterpump and thermostat this weekend and put a new cambelt on for good measure also. I'm hoping that i've either a jammed thermostat of the impella's have broken up in the water pump. If not then next step will be the headgasket. Please let me know how you get on with yours and vice versa. If anyone else has any input then please feel free to help us out, thanks+++ Link to comment Share on other sites More sharing options...
vwman Posted July 2, 2009 Report Share Posted July 2, 2009 Today I noticed water dripping from under the engine,it has now stopped but have no idea at this stage as to the source.There are no warning lights on and no issues with the temp. It's a 2002 1.9tdi 130bhp Will take a look again in more detail in the morning. Any suggestions would be great... Link to comment Share on other sites More sharing options...
