In southern Arizona, we typically will have days where the temperature is in the 102-106F range (sometimes hotter). In looking at the engine arrangement in my car, it sems to me that with the car idiling in traffic or moving slowly, there will be a significant amount of hot rejected air being recirculated into the engine again. So far, the oil temperature indication has not gone more than a couple of degrees past vertical on the temp gauge.
Anyway, I try to avoid driving my car in slow traffic and not driving during the hotter part of the day (10:00-18:00).
Am I being too paraniod? Has anyone in the club done any temperature profiles/analysis of their engines in a hot environment?
Any insight will be greatly appreciated. Thanks.
