Well..

I have a 99 Civic EX overheating on me, when I pulled over I noticed that the Cooling fan is not running at anytime when I cycle AC or when the car heats up. So, I checked Fuse, Relay, and put voltage to Cooling fan and everything checked out okay.

I jumped the coolant temp sensor located behind the distributor and the fan kicked on immediately. Went down to the auto parts store bought a new one and replaced it, but still not working - took it back got another and still not working. Also, the connector fits perfect except the clip doesn't make it all the way down to click and secure.

Could really use some troubleshooting help w/ this, thanks again.

 

Have you bled the cooling system?

 

From the valve in the bottom of the radiator, I drained out all the coolant and topped it off with new coolant. I have been going through the Chilton manual, looking at online postings, but I am lost on where to go next.

 

You replaced the coolant but you didn't bleed the cooling system.

Bleeding the cooling system may take 20-30 minutes.

1) Park the car on an inclined driveway with the front end higher than the rear.

2) Push/turn the dash heater lever/**** to MAX heat. Fan need not be on.

3) Follow the directions in the diagram below

 

Sounds like a plan, I will tackle this when I get off from work. Thanks for the help.
