Manifold removal (remove thermo housing)?

Wolf Spyder · 12-10-2006

The shop manual I have says that the intake and exhaust manifolds are removed together by unbolting it and lifting it out as one unit. Well the bolts on the collector were very rusted and as I am planning to put on a pacesetter header I cut the two pipes as high as I could with a cutting wheel (that's all I have) Problem is that when attempting to lift them out the hang on the thermostat inlet. Question is, is the inlet O.K. to remove so I can remove the manifolds?

TIA

Perfectly fine to remove the thermostat housing, There is a gasket that will most likely need replacing, you could try putting some RTV sealer on it, but I don't suggest it. Remember you will loose some coolant when you take it off so have a pan ready on the floor.

Ah c'mon now, RTV seals EVERYTHING!!! But don't take my word for it.

Water passages, oil galleries, fuel lines etc. etc. - Too much of it does!
