Default cooling fan

yesterday I replaced the radiator ( it was so clogged that it exploded the top part of the radiator by the top hose) on my ex-wifes 1994 civic. She doesn't have an owner's manual. The fan is not comming on. When should the cooling fan turn on? How can I tell if the fan works or is just woreout. Car has tons of miles.

Also does anyone have .pdf of the repair and owner's manual?

Any help would be appricated.

i believe it only turns on at a certain temperature(correct me if im wrong) so unless your in warm weather or doin alot of freeway driving i wouldnt expect to see it on. you could prob cut the power wire and hook it directly to the battery to see if it works, then reattach it to the wire going to its fuse or what not.

Park it in the garage, let it idle. When it sits for about 10-15 minutes idling, it should reach a suiteable temp for the fan to kick on.

It will come on and off in 1-2 minute intervals. If your temp gauge is showing it running mid-ways up, and it's not comming on at all, it could be a defective switch, or fuse, anything.

Check the wiring harness up by the fan and make sure it's plugged into the fan correctly, and check for any loose wiring. Also check the fuse box under the hood and make sure it's not popped. It could be a relay, anything. If you have a tester, you might prod the wiring and see if it's getting power where it should be.

I don't have a manual for your car :-(

thank you for the responses. I have checked the fuses. I did drive the car around for awhile and the temp guage was reading in the middle of the guage (9o'****).

Pretty much what everyone else said. The fan should turn on automatically when the internal temperature reaches a certain threshold. Just keep the garage at least half open.
