Both fans are running in a/c mode yet engine is overheating is this a themostat problem?
cjsollicito, it is possible, but it is only one component of the cooling system that can cause this. Here are a few others: ‘‘‘Water pump malfunction Worn or loose drive belt’’’ Thermostat stuck closed Damaged fins Clogged radiator cooling tube Excess foreign material (rust, dirt, sand, etc.) Reduced air flow Cooling fan does not operate High resistance to fan rotation Damaged fan blades Damaged radiator shroud Improper coolant mixture ratio Poor coolant quality Insufficient coolant Coolant leaks Radiator cap Loose Poor sealing Radiator Cracked radiator tank Cracked radiator core Reservoir tank Cracked reservoir tank Overflowing reservoir tank Exhaust gas leaks into cooling system. I would say start with your coolant first and work your way down the trouble shooting list. The attached images show you the location of the thermostat.
I’m a little confused by your question. Are you talking about the air conditioning fans running and the engine overheating? The air conditioning deals only with the inside of the car, not the engine. The engine has its own cooling system (fan, radiator, etc.). Running the AC actually puts more strain on the engine, since the AC compressor gets its power from the engine. When was the last time you had your engine coolant flushed? Chances are wherever you live must be pretty hot, and it’s the heart of the summer right now. My Focus is recommended to have its coolant system flushed every 60k miles.
