I believe that I have head bolts that have failed and according to what I have read on the this site my coolant loss is the result of coolant leaking into the cylinders because ofthese bolts. My question to the group is if there is a way to replace the bolts without pulling the engine. Doing the job with the engine in place would take much longer but I am in no hurry at this point. Any thoughts? My Seville has 160k miles and is a 99.
I just did that...take a look at my thread just below here. Read the whole thing though...I encountered an error in the FSM and in my last post, I specifically mentioned some things regarding your question.
Ideally you'd get an engine hoist, disconnect the subframe/engine/trans from the rest of the car (with a pallet jack underneath the subframe), use the hoist to lift the front end of the car high enough, and then wheel the subframe and contents out from underneath.

Re: Cylinder head bolt replacement
it is possible to do the studs in the car (we have had a few customers do it) its just the fact you might as well pull the motor because its about the same amount of time and probably a little less effort.
