Head gasket sealer

6 years 9 months ago #139150 by Mikstur
I have found a small leak from my newly fitted head gasket just above the alternator. ( described in the topic " loosing coolant") The coolant is leaking OUT of the the engine and is therefore not a dangerous leak . There is no sign of any internal leak. I wonder if it was worth trying a liquid head gasket sealer. Has anyone experience with this? How do I get it in the coolant system. If I pour it into the expansion container it will take days before it reaches the engine as the leak is small. Can I bleed the system from the radiator?

used a hg sealer some time ago with a Hyundai Accent which started to smoke and
had some mayo on the oil cap.
It's filled in the radiator directly.
Run it for another 20k mls without any issues before I sold it.

'Blue Devil' seems to be the best brand.

But not sure if I would use it with the TF also... :-?

If its leaking out of the engine maybe torque up some bolts to seal it?

Is liquid head sealer same as K-Seal? If so I'd stay clear of it.

I have found 3 different sealers on Ebay. One of them is K sealer. I will avoid that one

I've had HGF on my last monogram TF and a blocked rad on my current one. My current one the garage said it had traces of Rad Weld in it. It took em ages to clean it all out and i think it contributed towards a blockage in the coolant system.

I'd try if you can to find the exact fault as these head saver things are only supposed to be a temporary repair.

BUT.... My best mate graham works on HGVs he chucks that it as its company policy to do that first to keep the trucks going a bit longer, and he knows of engines that have done 60k+ and still going strong.

So choice is yours

The choice has to be yours, but I would never use that stuff on any of my engines.
