    Question about Derale electric fan kit for Jeep Wrangler TJs

    I called and they are there today. Tech support says that the replacement push in probe is correct for the controller I have and what I'm describing sounds like its working. That measuring temp with my code reader, seeing it drop to whatever temp may not be what the probe is seeing. The stock...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    I took your advice and added an auto resetting circuit breaker. Not thrilled that Derale used the same color wires for different things from the regular kit (positive switched) to the manual control kit (negative switched). I had the original done with all matching wire colors, and really did a...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    Update: I drained the radiator, then used Prestone radiator flush and cleaner. Two bottles when one would have probably been enough. Drove it for a few days, didn't do the 10 min flush. Drained that out and ran water for a day to flush the flush. Then put new coolant and a new thermostat in. I'm...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    Knowing me I got the thermostat from O'Reily's so I'm guessing not OEM. No leaks. My plan is to do a full flush when I have time. My Jeep isn't my daily driver so that helps, and I want to make sure if I need it to plow before I have a guest arrive at my cabin its ready. So I might just put...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    Some of the reviews I've read about the kit is that the fan goes out after a year or so. That makes sense if you use your Jeep for a daily driver the way the fan is always turning on, running for a few seconds and off again. I have to think the start up is the hardest on the fan, the relay, and...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    No with the kit you don't use the fan shroud. It was in place when I had the stock fan in place

    Question about Derale electric fan kit for Jeep Wrangler TJs

    I had to plow this morning. I drove around 70-75 mph to push the Jeep hard enough to see if it would get warm and it did. So now I know that the electric fan doesn't help anymore than the stock fan did. So its got to be the thermostat, radiator or the water pump. I replaced the thermostat and...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    What is the downside of using an electric fan? If I get this sorted out its easy enough to remove it and put the Jeep back to stock. I'm just curious why you say that? I agree that the stock system should be more than up to the task for what I'm doing.

    Question about Derale electric fan kit for Jeep Wrangler TJs

    Thanks for the reply jscherb. So could be my radiator. Or I wonder if the stock temp sensor thinks its hotter than it really is when there isn't any airflow. But it tells my highly accurate (lol) Jeep temp gauge that its at 210ish about any other time I look at it. I've got a project in the...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    Lets assume that the thermostat is working correctly. If the ideal temp range for the TJ is 195-210 degrees The thermostat sensor for the kit engages the fan at 199.6 degrees and shuts off at 188.6 degrees. I think the thermostat is staying open, I don't know if it would close all the way at...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    I replaced the water pump and thermostat a few years ago. I know that doesn't mean I don't need a new thermostat again. It is reassuring to hear jscherb say he has no problems, I should have posted before I changed to an electric fan. Do you have the stock water pump on your LJ? Could you post...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    I didn't put the fan on for any other reason than my Jeep got hot when I had the plow on it. Keep in mind this is winter in SD. Some days it would be below zero and it would overheat. If I dropped the plow and picked it up about 4 inches and drove it there was no issue. Its just that the...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    Chris replied to a thread you are watching at Jeep Wrangler TJ Forum. Derale fan kit for Jeep TJs Electric fan kits on TJs are a terrible idea. The stock fan is more than up to the task of cooling the engine, even in the most extreme temperatures. While I like Derale, running an electric fan...

    Question about Derale electric fan kit for Jeep Wrangler TJs

    I tried to search but can only find info on Derale transmission coolers. I've got a 1999 TJ Sahara the the original owner put a snow plow on and left it at their cabin in the garage most of it's life. I bought it a couple years ago and was thrilled to have found a Jeep in the Black Hills of...

    New to TJ's - need lift advice

    I can't blame the PO I put the Rough Country 2.5 “ suspension lift, N3 shocks and steering stabilizer, transfer case drop and rear track bracket on it. Then later I noticed that I ordered the 4 cyl kit instead of 6 cyl, but of course I had them installed them before I noticed so my front springs...

    How to sound deaden the interior of your TJ

    I just purchased some Noico 80 mil and the three tool roller kit off Amazon for my Polaris General. Glad to hear it worked well for your TJ. The floors etc of the General are plastic so I'm not too worried about moisture. As mentioned before on this thread I'm kind of worried about rust down...
