Car keeps overheating

I have a 2002 Honda Civic DX. It's been overheating on me whenever it is 85+ degrees outside. When the car overheats, the left fan doesn't turn on bu the right one does (looking from the front of the car and into the hood).

Before I do anything to fix the problem, it is the radiator fan that is messed up, right? If so, can you provide me instructions on how to change it. Thank you.

Re: Car keeps overheating

The left fan looking in from the hood is the radiator fan and if it doesnt come on then that is your problem.

Re: Car keeps overheating

No, that COULD be your problem. Test the fan, if it works then it's the fuses (#4 in the under-hood fuse/relay box and #14 in the under-dash fuse/relay box), or relay (in the under-hood fuse/relay box), or the switch (in the thermostat housing).

If you need a new fan motor. Best bet is to buy the assembly from the salvage yard for like $50. Just the motor alone at Honda is almost $200. http://www.car-part.com/

1) disconnect neg batt cable. 2) disconnect upper radiator hose @ the radiator. 3) remove body pins from top of grille. 4) GENTLY, as not to rip grille from bumper cover, pull grille forward and remove the 2 bolts holding top of radiator assembly. 5) push assembly rearward and remove the 1 bolt holding the overflow bottle and the 2 bolts holding the fan assembly. 6) remove old, install new, reassemble. Takes like 10-15 minutes
