[DML] Re: Water Pump replacement and Penetrating OIl

[tobyp@xxxxxxxxxxxx]

Dave - The only bolts that you have to be careful with are the steel 
bolts that are screwed into aluminum (grin).  You need to be careful 
to avoid cross-threading any and all bolts, but especially the 
intake manifold bolts.  They can be interesting.  Any good 
penetrating oil is good.  Many swear by PB Blaster.  If you run the 
car, the thermal cycles can help work the penetrant into the 
fasteners (that's a good thing).  It may stink and smoke a little, 
depending on where and how much you apply it.  Always use anti-seize 
compound for reassembly on every bolt, and replace the various O-
rings and gaskets to avoid a massive vacuum leak.  Change the hoses 
out under the manifold unless they are nearly new.  Other than 
that ... nothing to worry about.

penetrating oil and if so what kind.  Is it ok to use / run the car 
after applying the oil or will that make it worse by "baking it in"?
