How old is the cap? What if it's not holding the minimum amount of pressure?


If you own a Renix Jeep, you'll want to check this out.

My 94 runs about the same. It's been close to 100 degrees here in IL and she's been running about 210. I've heard turning on the heater does help too.

Agreed. In that kinda heat it's normal. Yes hood vents help.

How do u tune a motor to run 210-220? Does one change the tuning when the seasons (temps) change from summer to winter because virtually no motor will run the same temp in the winter as it does in the summer.

Man Law - hoods should be raised at least once a week.....have a look see.

I live in southern AZ, it's going to be 112f this weekend and it is rountinely well over 100f. That being said, the XJ cooling system is nominal at best in high ambient locations, anything you do to upgrade the cooling system needs to be the biggest baddest parts you can get.
cbenez1 told me that he has tried spacing the back of the hood up one inch (longer bolts and some form of shim) to help evacuate the engine bay of radiant heat. He also mentioned rear facing hood scoops with the belief that it is better to pull heat out of the engine bay rather than force air through it. I too am having problems keeping an XJ cool, I am trying the hood space trick to see if it helps, i'll let you know how it works. That will at least tell me if a hood scoop is worth doing. Good luck Jeff......

One would think ... that since the electric aux fan, is computer controlled to turn on at 218*f ... Then any temps higher than that ... would be excessive ..


Mine must be seriously "out of tune" - since it runs at 195*f all year round .. .. ..

Mine runs at 210 all day here in the Vegas heat. I removed my AC last year because of a shot compressor and broken condenser.

Mine used to run at 210 or above all the time. I replaced the fan clutch and water pump. Now it runs at 190 all the time (I have a 190 degree thermostat).

Unless I'm sitting in traffic on a 100 degree day with A/C on. Then it'll creep up to 210 or so. Hottest I've had it since the fan clutch and water pump was a hair past 210. It was > 100 degrees that day and I was wheeling it pretty hard and had the A/C on most of the day.

Removed 2 row, and installed 3 row. Went for a jeep drive. a/c on max, 93* outside, 50 city- 50 freeway it stayed at 195*. Once we got to destination, I left it idle for 10-15min (forget). We then left, it went up to 215* (between 210* and the next line). Drove back home. Came down to 212* (hair line off 210*) and maintained. Thought it might come back to 195* again (but didn't), maybe heat soak kicked in, unknown. But, I am happy. It ran much cooler. I can live with 195-212* in 93* outside a/c set on max. Before it was at 225* mark (line passed 210*).

Here is the fan clutch I put on the other day.

I have to ask, those who think they are running at 210*, have you verified this with a heat temp gun or something? I have, and mine is accurate.

I had the DRB factory scan tool hooked up to my 88 the other day. DRB is reading 195 and the needle shows about 215.

I used a laser heat gun, but i'd be curious what a scan tool shows.

Scan Tools and OBD-II data readers are said to display temperature readings that are 10* less than what is indicated on the dashboard gage.

Since older XJ's have 2 temp sensors in different locations, a wider variation in temp readings would not surprise me.


195*-210* is normal for the 4.0L, and seeing 215-220* under extreme conditions is also normal.

.

A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.

Fan clutch (heavy duty)
Aluminum 2 row radiator
New hoses
New water pump
180* t-stat
coolant sensor
Radiator cap
Synthetic oil change

I did also just did a comp cam and performance head swap along with a performance header. Do hood vents actually work? Anyone done it and can verify?
Hood vents are to help dissipate the heat being trapped under the hood, also known as heatsoak. IT WILL NOT REDUCE THE OPERATING TEMP OF THE MOTOR. That's a very common misconception around here.
