Hello. I'm having problems with my 91 voyager 3.0 overheating. I just replaced the fan and it won't turn on. I overheated it pretty good a few times recently. The A/C has not worked for years, but the fan did work until recent.

Where is the fan relay located ?

Also I understand the water pump is not an easy one to replace. I think it is leaking now !! Are there any schematics for changing a water pump on a 3.0 ?

Thanks in advance for your help

Hello again. I bought a Relay switch for the rad fan today. There are 5 Relays in a row on the fender. How do I know which on it is. I don't have a wiring diagram. Can anyone help on this.

Here is a site for the water pump replacement:

If you do the water pump you should replace timing belt at the same time since you need to take everything off to do water pump. I have also read that the pipe connector at water pump location may be faulty.

Look at the same site for testing the engine cooling fan procedure. I would think the cover on the relay box should show which relay is for each circuit. Also has wiring diagrams.

hope this helps

Thanks alot !! I'll check out these options !! much appreciate the info.

I have gone threw all of the possible sections on the AutoZone.com website and connot find the information I need. There are 4 relays on the driver side fender. I need to know which one is the fan relay. I don't understand the wiring diamgrams that I found on autozone.com. Very frustrated now !

Should be the one at the front. wire colors are Grey hot at all times. If there is not battery voltage you more than likely have a burned fusible link. Dark Blue is hot from ignition switch. Dark blue with pink tracer goes to pcm (relay control) Last wire is light green and goes to the fan.
