coolant leak

  1. General Technical
    Hi peeps. Had finally got the overheating problem on my 1997 1.9 T4 sorted, (wasnt cylinder head gasket, blocked rad,water pump, or fan fuses) was simply a case of replacing the pressure reservoir cap, which was venting at too low a pressure,and thus lowering the boiling point of the coolant...

    I have had a mystery coolant loss on my van since I bought it a few weeks ago, it is under warranty and I have been using my regular garage to try and diagnose it. I drove to Cornwall (200 miles away) and after the drive once the van had cooled down it struggled to start again and hydrolocked a...

    Hello! Thought I'd share my experience of my recent breakdown as I'm still flabbergasted that a water pump failure can result in needing a new engine or at least a very expensive strip down and repair. After driving my T5 2.5 Diesel (AXD engine) for 60,000 trouble free miles I recently broke...

    I have had my van in the garage 3 times for a diesel leak that I am not 100% sure had been completely fixed and have been in twice for a major coolant leak. Each time it has been patched up and they have asked me to source coolant hoses as they can't find any?, I am pretty sure the diesel leak...

    T5 1.9 84 120k I think I have been unlucky and picked a problem van as already changed starter, engine mounts, drive shaft, anti roll bar links, front wrap around coolant pipe after just 7 months of ownership. My latest issue is it is loosing coolant on long journeys and under load, while temp...

    ?? Hi guys I need your help please, I've a 1999 lwb caravelle 2.5 TDI which I've converted into a camper. The drama I'm having is that I know it has a leaking heater matrix but I've no idea what type I require to replace it. Unlike any of the t4's I've seen mine has digital climate control that...

    My T5 has suddenly started to use allot of coolant. It can drain the expansion tank doing a 70 mile run. If checked the expansion tank and replaced it. There is a very slight amount of mayonnaise on the top of the oil filler, but it really isn't much and the goop that is there is grey rather...

    Hi all, 2008 1.9 TDi T5 (102ps, 60k miles), I had my battery warning light come on, measurements with a multimeter say alternator has failed so I removed it yesterday to get it tested/replaced. While underneath, I noticed there's a coolant leak from the back of the engine, seems to be coming...

    Hi guys I've been suffering from a coolant leak for a fair old while and its just started getting a tad worse. Under a heavy load uphill for a good 10 miles it done a fair bit of coolant, like max to under min, and I'm seeing a puddle where its stood. Also I'm steaming a bit where the coolant is...
