Customer Question

Does a 2006 bmw 325I run at a cooler temperature when ambient air is above 70 ? and then warmer in the colder temps ? My scanner shows that my engine temp varies between 150 and 160 F and the air tem is around 80
JA: Have you checked the coolant level? Have you checked for a leak in the radiator? Are you hoping to fix this yourself? What have you tried so far?
Customer: Coolant level is fine, installed a new tstat
JA: Anything else you think the mechanic should know?
Customer: nope
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the BMW Mechanic about your situation and then connect you two.

This morning I put the scanner on and found that the coolant temp matched the IAT so I believe that the coolant temp sensor is accurate.

this vehicle does not run at different engine temps based on outside temperature.

What would be causing the engine to run cool even with a different thermostat ?
Expert:  Steve replied 1 year ago.

that could be just normal fluctuation or an issue with the water pump, coolant flow or fan. As the original question has been answered please kindly CLICK ON a positive rating
