Engine Temperature Stuck at 160°F With Weak Heater Output
What the customer reported
The vehicle owner reported that the engine temperature was staying at 160°F under all driving conditions, including short trips and highway driving, for a few days. The heater was also not blowing as warm as usual.
What we found and did
The technician installed a new coolant temperature sensor and let the owner know the gauge may read differently than it did when the vehicle came in, since many vehicles actually operate between 195 and 220 degrees. The team also performed a BG complete coolant system flush, using the BG machine to withdraw and flush out all fluids from the engine and radiator, then refilled the system with new fluid using a BG fluid kit. The work was completed in one visit at our Frostproof shop.
