over heating

[dan3490]

well my friend bought a focus svt not to long ago it came with a k&n cai on it.... well he just changed the cai to a AEM i guess its a lil wider idk well anyways now his cars starting to over heat and the oil temp gauge says its hot too ... any clue what it could be?

i think its cuz the car has a stock thermostat but i could be wrong

any help would be greatly appriciated

....I seriously doubt an intake would cause the car to overheat, but then again its a Ford....

Make sure the thermostat is opening (both radiator hoses will be hot) and the fan is working. Without the fan cycling as it should, it would overheat when at stops, and idle. Hope that helps!

Sounds like you may have a problem with the fans. When you go down the road, it cools off right? If thats the case, the air flowing across the radiator is cooling it back off and the radiator is doing its job. Check out the fans or the electrical system for the fans namely double check the fuse under the hood.CAi shouldnt have anything to do with that. This should go without saying, but have you checked that coolant level?

its not my car... and he cant get it down here for me to look at it....so all i really can say it what has been said .... i dont know whats goin on with it personally because i havent seen it sence he started over heating... i told him check the coolant tubes ect like hrc said... i told him my self check the fan switch maybe a wire broke.... i just dont understand why all the suddent just from swapping cai the car is heating up...... maybe he broke somthing installing the new cai idk id really have to look at the car... thanks for all the help...

[dan3490]

i still think its the thermostat adding a bigger cai pipe wouldent that make ur engine run some what hotter ontop of that the heat the last couple days and hot rodding the car everywhere he goes expecially cuz he got a new part.....wont that fry a stock thermostat

[hrcDSM719]

....no, not really.... thermostats will go bad when they feel like it pretty much. My money is on thermostat or some sort of fan issue, along with the possibility of low coolant.

[dan3490]

well he said the fans dont turn on when they should but when he puts his heater on they turn on i said its the fan switch

[hrcDSM719]

Prob the fan switch, or the coolant temp switch that controls the fan.

[dan3490]

yea thats what i was thinking and ive been telling him to find it so he can test the fans by jumping em with a paper clip f***ing lazzy a$$ my friends 89 accord was over heatin thats cuz 1 of the wires to the fan switch was corroded off from the engine heat :P so i just rewired it took car of that prob
