Do auto repair shops install head gasket sealants or is that against their practices?
Posted by admin on October 27, 2011
I was referring to when you put head gasket sealant on a blown head gasket to stop overheating.
please i beg you don’t listen to either of them no disrespect to them at all intended, but anyone who knows what their doing will use aluminum spray or copper spray before installing a head gasket that’s not already done from the factory ,example: a reputable repair shop.
a reputable one most likely will not simply because it can cause a lot more problems, and its not even a decent quick fix. if the head gaskets blown it needs to be replaced. and if this is your situation im sorry i totally feel your pain blew one on the crabby dodge the other week now im fixing it the right way.

there us no sealant goes on head gaskets. the factory puts the sealant on them before you buy them.

Even though there is head gasket sealant stuff out in the aftermarket world, i would advice not to use them. All you need is clean surfaces and a head gasket. I work at a dealer in ky and as far as i know we don’t use sealants at all. Sealants would also cause leaks on the headgasket because it just needs to have two flat machine surfaces and the gasket, that is all.

Common practice is to no sealant.
But really clean, flat, straight surfaces.
Why would anyone even want to install a sealant on a good head gasket?
Most head gaskets fail because the car gets too hot.
The most common install mistake is not insuring that all the surfaces are clean…and I mean clean. And that the head has been check and machined to have a flat surface if required.

No reputable shop would ever consider repairing a blown head gasket that way.
