Hey everyone,
I thought I would ask for opinions on why my car runs warm on freeway trips. I installed a coolant temperature sensor in the block of my b230ft where the drain Petcock is last year. My commute at the time was ~40 miles climbing ~1000' and doing around 75mph at 3,200rpm during the hottest part of the day. Had a mechanical fan at the time and have since went to an electric puller fan, this made no difference in highway engine temp though. Newer radiator, 82*C/180*F thermostat, and fresh 50/50 type C coolant. Also, I used the prestone clean and flush stuff before installing the new cooling system components. Heater works fine and I believe the system to be properly bled.
My concern is when it was 90*F and above outside the block temperature gauge would stay around 200*F and not come back down until exiting the highway. Sometimes it would climb to 210+ and rarely 190 and below, agian during highway trips. Around town the e-fan does a great job, kicking in around 190*F.
The car seems to keep a good temperature during all other seasons. I'm now driving 2,000' uphill in the morning but it's cold But with warmer weather coming up I thought I would ask y'all.
Cylinder #3 reads 30 psi less compression than the others which seems to be being lost past its piston rings. I also have no cat and newer cat back exhaust. I haven't tested coolant for exhaust gas, is this recommended? Any other ideas as to what's going on?
Thanks for any help
