Do you have to change head bolts when you replace a head gasket on a 1986 Toyota Camry?
I'm not sure if you HAVE to, but i'd recommend it. Consider the many times those bolts have been stressed by repeated heating and cooling.
What is a cylinder head gasket?
A head gasket is a gasket the separates the cylinder head and the block. It separates the coolant passages, cylinders and oil passages. There are many other posts on this page that will provide more details. The head gasket provides a seal between the head and the engine block.
How hard is it to change the head gasket on a jeep liberty?
Replacing ANY head gasket is a labor intensive job. It involves removing many bolts and connections and then re installing them with the proper amount of torque. You will also have to drain, flush and refill the coolant system. It is NOT a job for a novice. I recommend taking it to a certified shop or dealer.

I replaced the head gasket. How many pounds of pressure do I need to apply to the bolts on the head?
Does your car always over heat when your head gasket is blown?
the answer is that if you blow the head gasket your car will overheat if you are driving any distance at all. You should smell coolant and see signs of leakage. It could be that head gasket is fine but you have had the bolts around the cylinder head work lose or be improperly torqued down. If you do nothing but drive short distances and the gasket is leaking at back end of clylinder many times it will just lose coolant of course this is serious too . If you see coolant leaking it is many times serious not just a hose or fitting .

What is the difference between a bad gasket and bad head gasket?
A head gasket is only one of the many gaskets in the engine. Each has a separate function and failure by any one gasket will result in different type of leakage. A head gasket failure is perhaps the most disruptive.
How many head bolts on a small block Chevy?

How many ways can you blow a head gasket?
The main cause of a blown head gasket is engine overheating. Of course it can be a manufacturing defect but that is not common.
Honda crv 1998 model you have change the head gasket but still water goes to the engine oil what is the problem?
It IS possible that the new head gasket was not installed properly - either the gasket slipped or the head was not torqued down properly or in the proper sequence (don't feel bad it has happened MANY times to LOTS of other people) - OR - there is a crack in the block itself and the engine might have to be replaced.
How likely is a head gasket to go again on a Renault scenic?
There are many factors to be considered in this - what caused the original gasket to fail? Was there head warpage? Overheating? has the head gone "porous"? Was the head skimmed (if needed) or was a thicker replacement gasket used? More info required.
Would it hurt to reuse the headbolts on a 95 2.0 Ford Contour?
You may be able to reuse them with not adverse effects if you make sure the threads are clean and not deformed. However many engines today use "torque-to-yield" (TTY) head bolts that stretch slightly when installed. This provides more even head loading and allows the bolts to hold torque better for improved head gasket sealing. When the bolts are installed, they're first tightened to a specific torque - then tightened an additional amount that's measured in degrees of rotation. This final twist stretches the bolts to their yield point and creates the elastic clamping force that provides more even loading across the head and gasket. Because TTY head bolts stretch slightly (only a few thousandths of an inch), some auto makers say they should not be reused when the cylinder head is removed. Reusing TTY bolts will cause them to stretch further, which increases the risk of breakage. A stretched bolt also will not hold the same torque load as before, which may cause a loss of clamping force resulting in head gasket leakage. The best insurance may be to replace all TTY bolts when rebuilding and reinstalling a cylinder head with new head bolts. So if your engine uses TTY bolts, replace them. Be sure and torque to the correct setting and in the proper sequence.
