The last few days in Chicago have been mid to upper 90 degrees. Some days I use the A/C others i choose not to. I have the 4.7 with the belt driven cooling fan that runs when the Jeep is started. Well its a stop and go kinda day and it was about 95 out and i was using the AC. I noticed the temperature gauge was over the half way mark. It was a hot day so i don't think it was that big of a deal. But i decide to pull into a parking lot for the heck of it and pop the hood to see if the electric fan is working.
It is working and both fans are running as they should, I know there is a low and high speed but i find it kinda weird that the electric fan was running at a 'low" speed. Especially when the AC is running, its 95 out and the temp gauge was over the half way mark. I have enough coolant and everything is good in that department.
I'm just wondering if anyone knows when the high speed cooling should be coming on if at all? Or if there are settings for this?
my 4.7 (new radiator, and water pump, and fan clutch) stays at about half way in the summer, especially over the past few days when its been 98ish. even with the a/c on, of course the electric fan fires up then as well.
Alright, it seems that the consensus is that its not multi speed. I thought it would have been multi speed or something. I just assumed that mine could possibly be due to my dads intrepid having a low and high speed and my moms WJ with the HO also has a low and high. (They sound like jet aircrafts taking off when running.) In the case of my moms WJ, the HO motor does not have a belt driven fan, perhaps this has something to do with it having a multi speed system. Thanks for the insight.
Bro i got a 5.9 with the ELE fan and a 180 stat and a flow kooler high flow water pump and when it 95 i run 210-212 all day long lol....mine does same thing
Ya i'm not sure what the actual temp really was cause the wk just has that goofy H/C gauge with no numbers (stupid). but it was just about 3/4 to hot so it was just cause for concern cause i never seen it that high. Hasnt happened since so i'm not going to worry to much.
GM used to have the best instrument panel for their trucks and suv's. I cant remember which suv it was but i want to say escalade... It would have the battery, coolant temp, oil pressure, fuel of course, Transmission temp, and oil temp. That was the ultimate if you really wanted to make sure your truck was running well. Probably for folks that towed and hauled everything. I think in all the new suvs they did away with all that.
I pass people on the way to my cousins lake house ,I guess I never really payed attention to it ,but were going there again this summer so I'll check the temp this time round.
Yeah that was the only issue i ever had with that wrangler. I had to do 50mph with the heat on blast all the way to my sisters house in raleigh. It was 90 degrees with typical nc humidity for labor day weekend. See I had the radiator replaced about 4 months prior, the ****ers put a ton of leak stop in the coolant with the new radiator. When i pulled the stat it was caked with the infamous leak stop flakes. Even though the problem was fixed it made me want to get rid of it, hence i now have my grand cherokee. So in the end, if it really starts to over heat, have pep boys or advance pressure test your radiator cap. Then make sure your stat is not clogged.
Yeah i suppose i can check it out sometime later today. I mean the truck only has 35k miles so i couldn't imagine any issues with the coolant but ill look into it.
I hear ya on the Chicago weather!! i can't drive with my a\c on without overheating, i think i still have baked mud around my radiator. i will be buying a large 180 stat and trimming it to fit my WK in hopes that it helps out a bit.
Let me know how it goes with that 180 stat. There was supposed to be one by JET that was supposed to be a really close fit but i don't know or have seen anyone trying the darn thing.
Yeah i mean if you are getting that dirt on the rad. just take the grill off and give it a nice washing. While driving again through flooded streets by me when i used to have my oldsmobile, i had water up to the bumper. Didnt know radiator was covered with grass and leaves and other storm debris. The radiator was not visible on the intrigue of course. Next day the sucker overheated. I was like man what the heck stupid flood... but then when i looked at the actual radiator it was just caked. Cleaned that off all nice like and no problems.
