How do you replace the head gasket on a 99 Cadillac catera?

Do I have to drop the engine to replace the cylinder on my 1999 cadillac catera with a Northstar engine|||Replacing a head gasket is not a DIY job, unless the person has plenty of experience, knowledge, and the proper tools. The fact that a you would even ask, "How do you replace the head gasket", would indicate to some that you should not try to do that repair.





To replace a head gasket you must remove the intake manifold, exhaust manifold, valve train, and then the head. This is very involved and requires disconnecting lots of sensors and the ignition system. The head must then be checked to see if it is warped, or cracked, and repaired if necessary. You must then know how to put all this back together and torque all the bolts in the proper sequence. This takes training and skill which the average shade tree mechanic does not have.





If you are dead set on DIYing it, get a vehicle specific repair manual and dig in. Good luck
