No! I can't use.
If you mean it suddenly started loosing coolant, then look for a leak. If you see no leak then suspect a blown head gasket. Stop driving the car until you get this repaired. If you continue to drive a car with a blown head gasket you will destroy the engine.
Never use sealant for a head gasket! It is used as a quick fix for cracks in the gasket but will not last very long. Safer to get the job done correctly.
It will wear them out and most likely cause the head gaskits to blow again. It better to use new head bolts.
Yes. -Unless your manual specifically calls for it, you never use anything but the recommended gasket
The car was damaged beyond repair.
If you think the car will be of use for a decent amount of time afterwards, then sure. If it is wearing down and suffering other problems, then probably not.
dont do it !
you should never use a sealant on a head gasket as that is only a temporary fix in an emergency situation. The only permanent fix is to replace the gasket.
not unless you want to cause more damage or end up seizing the engine and fitting a replacement,
Not likely.... I'd never use anything "temporary" on a head gasket.
It Could Be Any Of The Three.Remove The Head, Have It Tested. After Checking Gasket. The Head May Be Warped From Overheating And Normal Use. If The Head Gasket Is OK. I Suggest To Have The Head Tested. But The Block Could Be Cracked. If The Car Has An Aluminum Head As Most Do It Probably Is The Head Is Cracked. Heck Run It By A Good Radiator Shop And Have It Tested Under Pressure. See What They Suggest. Sorry To Be Of Such Little Help. My Bet Head. Best To You
NO! These type products are only an emergency repair. The only permanent repair is to remove and replace the blown gasket. Besides these type products can cause clogging of the cooling system. Do not use them.
