The engine is actually a 5 cylinder (which is not one of the choices on the drop down menu.) It is a 2.4 ltr turbo. The head gasket was blown and the radiator and coolant reservoir filled with a slick chocolate-colored ooze. I am replacing the gasket, but was wondering if it is always necessary or recommended to also CHANGE THE BOLTS? Or is there a procedure (e.G. Length measurement) to determine if existing bolts are satisfactory for reuse. ALSO, I have seen different sources conflict on recommending putting oil on the bolt threads versus putting sealant on the threads (and some oil under the head of the bolt, of course, for torquing.) What is your recommendation.

Thanks,
Joe

I would replace them, any bit of wear on them or build up can affect the torqueing of the bolts and they may be overtightened or tightend and loosened up.

Keepsealant pput on it to a minimal to not affect readings.
