Coolant Overheating Issue

[Deleted member 59498]

For sure sounds like a dealer needs to take a look, good luck with it hopefully something easy to work out.

This similar thing just happened to me - 2018 Jeep Wrangler JL. I went to the ORV park, went through some pretty thick mud a few times. On the way home, would get really hot, when not accelerating would drop some in temp. Washed under the hood, what I thought was really good - no luck, still kept getting hot. Washed under the hood again - special attention to the radiator/fan area - again no luck. Took it into the shop, apparently the mud had packed the radiator fins - mud was almost like cement. Had to take it apart and clean it out - fixed - and luckily no damage to the engine.

Certainly not normal. my coolant temp runs in the normal range whether doing 75 MPH on interstate or towing trailer with UTV 65-70 mph.

Whoa!!!

Mud blocking the airflow in the radiator. I wouldn't have expected that. Yet... So logical with a Jeep.

Thanks for the info.

Always looking for that European OEM functioning vented hood for the Wrangler. No luck so far.

Have you seen our H.E.R.O. Hood? Dual stage heat expulsion vents AND true cold ram air functionality:

One should never power wash a Radiator, because it can bend the cooling fins. Only use a garden hose, on the rain mode. So I suggest that you start by looking at you radiator cooling fins, to see if they are bent closed.

That's nice clean OEM look. Definitely not like the other aftermarket options, "look at me, I'm a mall crawler"
Q: Do you have any first hand experience with temperature results after installing one of these on the 3.0 diesel? I noticed you have a 2008 JK, but your profile shows a JL with this hood. It appears the designed Hood went into production for the JK. I did not know the JK's to have problematic heating issues, having owned one myself 3.6 Looking into this product it appears this is when these hoods first seem to come out for the JK. I could be mistaken but it does not look like " scoop/ram vent" design did not change at all from the JK to the JL, other than the obvious hoodlines, mount points and design differences in JK versus JL. To my knowledge the only JL that has heat issues is the diesel. I don't see how a one design fits all is possible here. But it leaves me intrigued especially if there's some real temperature tests behind the install of one of your hoods on a diesel JL. Given that if those tests or testimonies are true and effective, I'm ready to place an order. Please share any and all positive feedback on proven diesel JL experiences.

Thanks

Your oil is 255 on flat ground?

Our JK Heat Expulsion Hood (https://totlinnovations.com/jk-heat-expulsion-hood/) and our JL/JT H.E.R.O. Hood (https://totlinnovations.com/jl-h-e-r-o-hood/) are two completely different designs. The majority of our JK customers either had a supercharger, LS, or Hemi swap done. JKs with one ton swaps, bumpers, 40" tires etc... get really heavy and the engine is producing quite a bit of heat inside relatively small confines so getting heat out of the engine bay was very helpful.

Plus when we released our JK Heat Expulsion Hood back in 2013, there werent many options out and everything that was available, was quite subtle in design so we wanted to offer something more aggressive.

Our JL/JT H.E.R.O. Hood continues on with our 2 stage vents to help expel engine bay heat at both crawl and freeway speeds. In addition, we added true cold ram air to get fresh dense air to the engine.

The market has changed quite a bit since 2013. China has produced a less functional knock off our JK design so we wanted to innovate yet again. This time around we went for a much more sleek look. You almost have to do a double take when looking at one of our H.E.R.O. Hoods to see all the features.

I can tell you a customer with a 5.3 LS and our JK design tracked 10-15 degree drops in intake air temps after switching to our hood and another JK customer with a 5.7 had overheating issues in LA traffic before getting our hood. After that, no issues whatsoever. One of our JT customers reported that his rig feels peppier akin to a sportier setting on his Ultimate9 than what the Jeep was actually set to.

We have been hesitant to report metrics because we have been pulling our hair out trying to figure out a "scientific" way to gather metrics without having to go to an automotive test facility (unfortunately out of the budget). We have some ideas and hope to gather some info this summer.


Just a bit of back story but I bought my JK new in 2008 and got hooked. Began modifying it and exploring the Colorado trails. There werent any options on the market at the time that would fit the Avenger Supercharger kit that I had so I decided to be a little entrepreneurial and started TOTL Innovations. I have A LOT of money sunk into my Jeep and she holds sentimental value to me so I didnt upgrade to a JL when they came out. The Avatar image is a customer's JL.

Well I appreciate your response and appreciate the history of the turbo charged 3.9 and 5.7 L hemi and LS swap. That was definitely an era when many were seeking horsepower and increased tourque and there were no OEM options. I also respect that you took the pluged and addressed that with your own design. That then and now stands so far right field from where I started and my current needs. There are several reputable YouTubers out there that completely built their JL Ecodiesels and show actual results of the rig overheating going into limp mode. While I don't agree with their over-the-top setup (rooftop tent and a ship anchor on two wheels behind them), while pushing this diesel as if it was a gasser. Heat is an issue for some depending on how far they want to go. That is where you could find the fit. But with your feedback and searching all the reviews of your hood it's mostly all about looks and no mention of JL Eco diesel. My suggestion to you would reach out to the guys over at TFL Offroad located in Colorado. They have done tests on the high elevation steep grades with many trucks jeeps and similar type vehicles. It's Not Over the Top or have to be expensive as you suggest. Just may show us needing or desiring a cooler running rig just what your hood may produce. Heck I'd even provide the EcoDiesel JL to do it in. Would be willing to run over there to Colorado run some of the same high elevation grades that other Eco diesel enthusiasts have experienced the limp mode due to excessive heat. Then run the same with your hood. Its not an exact science in a laboratory setting but more of a real world. If it prevents the EcoDiesel from going in the limp mode due to excessive heat and truly shows cooler temperatures, on the very same course, that's proof enough for this guy.

Did you get any more information on over heating?

I have ran mine pretty good over the last few days, it was constant 215f with some 221f degrees on long mountain pull. But went back and settled at 215F, just putting this here for information. That was with ambient temprature of 37F to 68F. Alaska if it rains gets cold pretty quick in elevations but 215 degrees was almost the constant when level.

Coolant temp was always 203, it may have changed some but not much.

I watched these numbers on 140 mile run into some mountain ranges non-stop run. Never over 221.

 

[ChuckQue]

Hmm. Oddly enough I’ve been having some higher than I’m used to temps lately. Just running regular flat-ish freeways here at 70mph I’m getting 221-227* oil temps and 215-218 coolant. I know the ambient air temps are starting to warm up with us having an 80* day yesterday, but something seems off.

I checked around underneath and saw my oil cooler was caked in mud so I hosed that down but zero change in temps. Radiator looks clean from what I can see. Might have to pull the front end apart to get a better look.

 

[zouch]

when you say “normal range”, what numbers are you talking?

i hope you’re not referring to the bar graph coolant temp ‘indicator’; that thing almost doesn’t move even though indicated temps vary 50°F.

Certainly not normal. my coolant temp runs in the normal range whether doing 75 MPH on interstate or towing trailer with UTV 65-70 mph.
