Altima Engine cools while driving Sign up here!

The heater will cool down at the same pace. Car is fine when I drive in stop and go traffic or at slow speeds. I have tried changing the thermostat.

Hmmmmm. You should be using a 192/195F thermostat. Improper install, or just defective? Buy a good quality stat from the dealer or a parts store like NAPA. Could be a gasket leaving a gap for coolant to bypass?

New or not, thermostat should hold its designated temp or something's wrong. Coolant is slipping by somehow, T dmac0923 Enthusiast Jan 27, 2009, 7:06 AM Post #4 of 4 (2792 views) Re: Altima Engine cools while driving Sign In just throwing something out there......are your fans working???? if not the engine is getting hot at idle/low speeds and then the highway speeds force more air through the radiator causing more heat exchange __________________________________________________ 2015 Jeep Grand Cherokee 2002 Ford Ranger 2004 Toyota Corolla 1969 Ford Mustang Mach 1   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
