Can the MAF cause the car to overheat? 89 chevy camaro 350 TPI. I've changed the radiator,thermostatand water pump already. and i even trie bypassing the heater core. any suggestions?

 

Buy a hypertech cool fan switch it worked wonders on my car. Also make sure your lower air dam is intact. Have you checked to see if your fans are coming on correctly?

 

do you have eletric fans or manual? coolant level ok? any leaks from freeze plugs? you will have no heat if you by pass the core.. What thermostat are you running 180 or 190. When it overheats try turning the heat on, it will take some heat off the engine then turn the ac on it will automatically turn the electric fan on the secondary fan..
