OEM thermostat is likely a 195 as are most vehicles now. So 200 would be about normal operating temperature. When climbing a hill you may see about 210 or so at which point the clutch fan should start to engage causing a loud roaring sound. If this does not happen i would suspect a bad fan clutch.
The large fan within the shroud of the radiator spins at all times but does spin faster with higher RPMs I believe.
I am thinking a 195 or 180 stat now, but still tossing options around. And yeah it only nears 210 when climbing hills or lots of stop and go. Idealy I would like to be 200 tops though. Maybe I am expecting too much of an '88 V8 big block hauling max weight?
Mainly it just gets the hood, grill, interior heat shielded 'hood', and anything near the manifolds and exhaust hot which concerns me about wear on components. I did heat wrap the exhaust pipes for the EGR tube, and the exhaust near the oil pan and starter. Also heat wrapped the purge valve solonoid because it was almost melting after a longer drive.
Does the engine computer take a long while to adjust things after a timing adjustment? Perhaps I havent driven it far enough? I wondered about that as well.
Thanks!
