I have a T4 2.4 from 1995 with a gasoline engine. I noticed that over the last 300-400 km of riding I have lost 150-200 ml of antifreeze coolant. A few months ago I had a severe leak due to a ripped tube and this got fixed. Not sure if the leak now is connected to the old leak, but this time is...

Hi All, I have owned a mk2 golf GTI cab in the past and had such great help from the forums, so i have been on these forums a little, sorry if I get any etiqeutte wrong!!! It’s been a while... I have now bought a VW T5 2007 transporter, to convert into a camper. On the face of it, the van...

Good afternoon, I’ve been an avid reader here for some time, knowledge here is unsurpassed 👍.. I currently own a T5.1 2010 140k on the clock. Engine has recently developed a coolant leak, coolant is clear of oil as is the reservoir tank. I have narrowed down the leak to a section shown in the...

Good afternoon.. Did the usual Oil Change on my Van today, figured while I had the under tray off, I would give the coolant a flush and change as I haven't done this since buying the van. I dropped all the old coolant out and flushed through the radiator with a hose. I refilled the system...

Hi everyone, hope you're all okay and healthy during this lock down.. I am just putting this up here for some guidance on a Coolant Change and flush.. I've got a 1998 T4 Caravelle LWB 2.5 TDI (ACV Engine) . I've done plenty of coolant changes/flushes before on my other cars in the past but...

My 2015 T5 has pink coolant. The recommended coolant is G13, which as far as I can see all seems to be purple. I'm changing cam belt so it's not just a top up. Should I use purple G13 which will mix with the pink coolant. The current pink would have been the factory fill. This website has a...

Hi - I have a '03 T4 with 190k miles in really good condition (no oil drinking or smoking) Just recently had the water temp warning light on - pulled over, header tank is low - topped up with coolant mix (carry spare and oil) Did 150 miles that day with no light back on. Left for a week...

Hey everyone, first post, after reading the forums for a few months I finally got my hands on a T4 Kombi Petrol from 2004. I removed the mat and the plastic vent on the floor behind the driver seat to do a deep clean and noticed some smell (I think it's coolant) in the cab after driving for 20...

Hi All, We have started to loose coolant, slowly. The low level light is on, which is good, because it mean sit's working! We still have some coolant in the bottle and I was about to drain/replace and decided to warm the enging up first. Noticed a leak from under the van - dripping from an...

So I have the optional VW modified CANBUS Thermo Top C on board which acts as a supplementary heater to boost the coolant to operating temperature on cold days (<10C) In my last Caravelle I installed the engine preheater / parking heater upgrade to defrost the window in the winter and pre-heat...

After installing an Eberspecher I removed the rear heater but I did not pay attention to the flow direction of the rubber hoses. I want to install a calorifier and need to know in which direction the coolant flows. Is there something to test this maybe open the circuit again with the hoses in a...

Hi, newbie posting, so hopefully someone can help. I have 1.9 Tdi (2006) LWB T5 (136k miles) and recently coolant alarm light flashes upon starting the van, most notably if it has sat for a couple of days. If you look at the expansion tank, the level looks a bit low. My mate says this happens...

hi all, i have a T5 AXE engine Caravelle. I recently experienced difficulty starting in the mornings. Then noticed diesel in the coolant reservoir . I flushed the system but diesel seem to get back in the coolant. I've been told that it could be related to a blown cylinder head gasket. Any ideas?

Still cant chase off this leak and after doing the thermostat amongst some pro-active refurb work, I think I have located the leak's.... Coolant is pooling under the sump, which looks to be over the power steering pump too, which I assumed was running off the thermostat pipe. I think coolant...

Hello! I have a mystery to solve on my van: The mystery of disappearing coolant About two months ago my van asked me nicely to top up coolant, which was the first time it happened after 4 months and 3000 miles of me having it. Since then I had to put in 2 litres of coolant and I did around...

After a nasty diesel leak from one of the fuel injectors in the engine bay, I now find most of the rubber coolant pipes are splitting and or blown. The solution would be to replace those damaged pipes with new pipes or try and patch as a temp fix. Anybody have any recommendation as to where...

Hello! My T4 is losing water. It's gradually got worse so now I can lose the max to min level in about 200 miles (and I drive about 80 to and from work every day). Coolant seems to be coming out multiple pipes at the bottom of the engine near the thermostat and the radiator. I've...

Hi everyone, This is my first post but I've enjoyed this forum for a while now, it's so awesome to have all those brains working together. Now I do have a problem myself... When I was prepping my van for a trip to Finland (-35c°) I saw the garage owner put the wrong coolant in. (He changed...

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...
