I have a 98 S70 T5 with 101k.

The car was run overheated and now the head gasket needs to be replaced.

The radiator has already been replaced.

I have been reading about this and have started the process.

I have several questions:

1) When removing the head, does both the top of the head come off together (I am assuming yes).

2) Which bolts are the ones to accomplish this as opposed to the ones that split the head.

3) I was going to fashion my own cam locking tool out of plywood and 3/16 diameter bolts. Has anyone done this?

4)I am at the point where I am trying to remove the exhaust manifold. The bolts are difficult to see. How many are there?

5) Do I need to remove the turbo to remove the exhaust manifold?

6) Is there any reason why I can not leave the manifold on and remove it with the head? I can remove it on the bench if I need to. I have access to an engine lift to help with the weight.

7)Does the same theory apply to the intake manifold?

8) I hear talk of a chemical gasket. What is this? Is it used along with the mechanical gasket?

9) The mechanical timing belt tensioner was replaced at 70k along with the timing belt. Does it need replaced now or will it last till 170k? I also read something about a temperature issue with installing this. Does anyone know about.

I know lots of questions, but knowing these things will be sure to help.

Thanks....
