I cant understand how people like that can be allowed to trade as motor mechanics, but I can really- the mind boggles but apart from me boggling I just hope for the best for you and the car. Chris.S.

That's nonsense David. It's the thermostat housing 'O' ring which is leaking. It's a known problem which I have posted about many times. It's caused by the 'O' rings flattening. The solution is to fit new 'O' rings and make sure that the straight pipe clips are positioned correctly. You do not have head gasket failure.

Absolutely 100%...find another garage.

Any mechanic who would rather chuck a bottle of this gak in an engine rather than fix the issue properly, is best avoided

Some coolants have an additive that changes colour if it mixes with combustion gases ( Toyota ForLife springs to mind, usually its red but turns yellow if HGF). For ordinary coolants, you can source a kit that will detect combustion gases. Steel seal ( and the like ) is for Bombsite Car dealers ( or to chuck it in the cooling system prior to an auction sale ).

If the sealant was only added a couple of weeks ago, I'd strongly suggest doing a thorough flush of the cooling system. Use a hosepipe in every direction and do a ten mile drive between flushings. Use a proprietary flushing aid with the last two flushes. Getting the system hot and circulating before each draindown is important. This should remove the 99.9% remaining sealant that doesn't fix the leak and begins settling out in the wrong places. The singular mistake people make in using these convenience gloops is to leave them in the system. After all, flushing the cooling system is a pain in the butt. Even though they stop the leak (typically within ten miles), sealants don't repair the failed component. Strictly a get you home fix.

How much did they charge you for destroying your car?

I can't believe a garage would suggest the use of this bodgers delight, let alone actually use it! Get it out before it actually starts new issues.

The garage didnt charge for doing the job they only charged for the Steel Seal £35. Ive been driving the car for most of the day with so far no leaks. How long it will last is anyones guess but after reading all the comments i feel a little sick.
