I have been experiencing marginal cooling in my '82 for several weeks. Seems to do OK around town (gauge usually stays in the lower 1/4 of the green) when i cruise around town for more than 30min it will get up to the 1/2. After about 15 min on the highway it creeps up to about 3/4 then it nevers cools down again.
Fan shroud in place
replaced fan clutch some improvement, but minimal
To completely rule out the thermostat is just took it out. I didn't know what temp had been in there before (160, 180, and 195 available, and this thing always runs alot cooler than my 79) I am now running without one and the temp is staying just below the green or never more than 1/4 of the way in the green.
Can I run too cool? I know that it will take longer to warm up, I know that the oil viscosity will be higher (my PSI seems a little higher, how can this be bad in a GW?). It's in the 90's here and i might not put it back in until October. opinions?
