1.8T coolant leak help
Hi,
Noticed a small pool of coolant under the car and on further inspection I can see a serious leak when the engine is running that eventually slows when the engine stops. Coolant is running down the front of the sump and appears to be coming from a above the oil filter but below the exhaust manifold I can't quite pinpoint where it is coming from. No signs of water in the oil so not thinking HGF. Any ideas? Are there any gaskets/pipe connections in that area that I'm just not seeing? Any help greatly appreciated Many thanks Chris |

Could be the small coolant pipe on the turbo has perished. That happened on mine years ago, £52 for a replacement then! A few cms long with a bend formed on the end. Not difficult to replace. It's in a place that gets a lot of heat.

Yes, that's the one. My car doesn't have a PRT, the pipework is somewhat different, thermostat behind the engine. I think the pipe shown is same for both types of cooling. The pipe failed under the clip on the turbo and the leak was quite hard to spot

Thanks, just checked that pipe and it's dry as a bone.
I've taken some photos of the leak in case anyone has seen similar before. Any more ideas, I don't think it's coming from the water pump area (pic 2) what about the sump gasket? https://drive.google.com/file/d/1Q56...w?usp=drivesdk https://drive.google.com/file/d/1QPS...w?usp=drivesdk https://drive.google.com/file/d/1QCJ...w?usp=drivesdk https://drive.google.com/file/d/1QDw...w?usp=drivesdk Last edited by chrismyerz; 5th April 2021 at 13:03.. |

Inlet manifold gasket would be my first port of call 😎

T Cut covered almost everything there , Will just add that MLS Gaskets have been known to leak between the layers . If draining the cooling system ,I would look at replacing the coolant tee piece with outlet for turbo (if plastic) for an alloy one as the plastic is a known weak point for failure and can cost your engine. https://www.dmgrs.co.uk/collections/...g-zt-pfk000040 Last edited by TourerSteve; 5th April 2021 at 18:54.. |

Thanks all, I've gone through T-Cuts list and checked as much as I can without much luck, I think I'm going to take the advice and take to my local garage.
Will report back any findings Best regards Chris |
