Mine runs only when the pcm triggers it to come on, that is when the temp reaches 95 degrees, and goes off once it cools off. Now that it's winter, and very cold out, the fan doesnt even get to come on when am driving.
Am glad you stripped it down, and got to the bottom of the issue. had a similar issue on my LS swap where fuel trims numbers were suggesting that i had a vacuum leak. Deleted the egr, and replaced a coil, now i have full power again.
Nice nice, that engine will be like new when you are done. Love projects on old school cars.
I would definitely go with the gen 3 ls out of the 01. It's solid like a rock, and very very simple to work on, with alot of online support.
Yea I got this inline fuse from summit, 6 gauge and it's huge!! I will just replace my current inline fuse with it which has a 8 or 10 gauge wire.
The fan doesn't sound too loud, again I have the hood off, and no exhaust yet.
Do we know how much cfm the fan is rated at?
The fan is up and running, without the small black/white wire, so I guess it's running at full speed.
What size is the power wire going to the 60amp fuse? On the fan connector, one side of the power wire looks like 6 gauge and the other side 10 gaude.
There is a gap between the fan and radiator due to sizing the shroud to make it fit. Will that affect it much with air lost?
I only have 18" to work with for fan.
How! Just a $100??? You stoll it. I have not seen those in years..will be a nice fun project. Share the link to the build if you document it.
Thank you for the diagram, hard to read some of it, but what am after is clear on it.
With the replay in place in my setup, I am wondering if I still...
Ok, I will source a 60 amp fuse, right now it's on 80 amps for that battery wire. The green/yellow is going through the relay, so should be fine there.
The ls swap is work in progress but close to the end.
Thanks
Totally get it and appreciate the info. I had to make that one mod so it works for my application. I am using the fan on a gm ls 5.3 into a Jeep wrangler..
Do you know what size fuse is between battery and fan wire? And how many amps the fan drows?
I made the green/yellow hot only when pcm sends a signal that the temp has reaches for fan to run. If you make it hot when car starts fan wouldn't run all the time.
I got it to run on/off only when temp reaches the level by connecting the green/yellow wire to to pin 30 on the relay. Fan turns on whn temp is at 95 degrees and off at 80 degrees.
H ow much amps does the dan draws? I have two 40ams(80amps) inline fuses between fan and battery wire. I was...
