"Overheating" explained - a bit long Posted by NCSaab [Email] (#973) [Profile/Gallery] (more from NCSaab) on Sat, 12 May 2007 14:30:15 In Reply to: Overheating Some More, B. Millar, Thu, 10 May 2007 13:03:40 Members do not see ads below this line. - Help Keep This Site Online - Signup |
It is quite normal for the engine temperature to rise after the engine has shut off. Think about it: the engine is creating heat while operating. The cooling system is there to keep it a controlled temperature - this process requires moving air across the radiator, oil cooler & trans fluid cooler. When the engine is shut off, the cooling process stops. The heat in the engine block dissipates through the mass of metal and coolant. The coolant that the temperature sensor sees will increase in temperature as a result. How much? That all depends on the engine temp when shut off, the outside air temp at the time and how much ambient air flow there is Dead air like in a garage will have a higher temperature increase than out in the driveway where there is still a bit of possible airflow.
This does not discount the possibility of the thermostat not behaving like it was brand new. Just something to consider before going off and spending time/effort/money.
Good luck!!
