Hello! First of all thanks for creating this forum and all the great videos you created.
My question is regarding a cooling fluid leak on my VW 2010 Golf Diesel.
It took me a while to locate the leak but it looks like it's coming from a bold above the oil sump.
Could that be a blown head gasket and a blown oil sump gasket? Also why is there no coolant in the oil and no white smoke from the exhaust if that's a case. I was going to maybe try a Stop Leak fluid but I would like to understand what it is before I try using it.
The car has a few more issues ABS indicators, etc. and might not be worth repairing and I don't have think I want to start the huge job of changing replacing the gaskets myself hence the Stop Leak option.
Photos here with approximate location of the bolt and dripping bolt here.
Thank you!
Is it impossible, the water/coolant is coming elsewhere, is running along the surface of the engine and leaving (falling down) at just that sump-bolt??
A.f.a.i.k. the 'oil sump' is the cover at the underside of the engineblock, that is bolted to the block.
As the sump is containing engine oil (and metal wear) normally, it contains no water, so water dripping from a bolt
points to a problem.
Suggestion: drain your engine oil and look for water in what comes out...
(in a bucket, after some time resting, the oil should be on top of the water).
are you sure it's coolant? It looks like water to me.
Try catching on some white paper
It is. I ended refilling with water as it keeps leaking so until I can fix it that will be it.
So I drained the oil and there is no water/coolant in there.
I'm going to try the sealant but any idea how the water (coolant) comes out of the bold (and don't end up in the oil sump)?
Thanks
