I recently had a turn-key 7.3 IDI put in my 93 F350 and am experiencing some overheating/close to overheating issues. I have had the engine in the truck for around 3 months. Initially, the truck ran cool all the time almost like it would not warm up. The other day the truck overheated. (Boiling coolant) Granted...it was almost 100 degrees outside, the A/C was on, and the truck had been running for quite some time however, it was not pulling or under any load. Now the truck is staying within the "normal" range, yet I feel running too hot without being ran under load.
I have used an IR temp thermometer to check the temps....here is what it looks like after about 30 minutes running on a 90 degree day with AC running....no high load or hauling anything.
190 at the upper radiator hose
210-220 across radiator
230 (highest temp)- just below radiator cap-radiator hose feels like it is under allot of pressure at this temp
When cruising down road truck heats up....
Maintains/slightly lowers temp stopped at stop sign.
Lowers temp when pressing accelerator.
There is no coolant in oil or oil in coolant.
I have "burped the radiator".
If the truck did not noticeably overheat the other day then I would just think that it is a faulty factory gauge, and the engine likes to run warm on hot days. However, since the truck always ran on cool side previously, not it runs on the hot/overheating side....I have to think something is wrong.
Any advice/suggestions?
