Engine temp during summer

[Rea1994]

Sorry to hijack a little bit, but from what you guys are saying, I probably need to replace my fan clutch then. Regularly when driving for extended periods of time, or going up a steep hill, I'll see temps around 216-220. Even sometimes when I'm just driving around the streets, I'll get to 202 usually and sit around there. Even when it is on the cooler side I'll get up to those temps.

I have an ARB front bumper, and otherwise I'm usually alone, or at most +1 adult around 200lbs. Stock tires, and the third row is out.

Yesterday around 90something degrees outside, AC on full blast in stop(more stopped)/go traffic and temp sat right at 202 deg. Is this normal?

 

[Rea1994]

That's less than I'm usually at without the ac.

Just got done crawling through Nevada (Mina area - cabin under the rock), 85F ambient, ~140F intake, sandy climbs with 2 kids, 2 adults, 65 lbs Lab, beer, sodas, snacks, gear under platform, Bajarack, 10 gallons of fuel, 33" tyres, 2.5" OME lift, ARB front winch bumper, winch, and 2 Hella 4Ks mounted on bumper, 10-25MPH climbs with AC on ~ 208F. My Hella 4Ks are the airflow killer. I'd say look at your fan clutch and possibly D/F coolant.

 

[Rea1994]

Yeah looks like I'll need to look into that. What is D/F coolant? Sorry I don't know much about those systems. More of an electrical guy.

I suspect drain/flush, which I need to get to. I had similar temp problems as op fan clutch rebuild took care of it.

Today. Around 100 degrees. 300'asl. 33s Gobi rack arb front bull bar. Snorkel, 2.5" lift. Unmodded blue hub with 20k oil. the second was sitting in my driveway at idle for a few minutes.

As long as it doesn't get above boiling temp you're good.

Another thread hijack. How did you get your scan gauge to read intake air temp? I've searched for code but couldn't find it. Thanks in advance.

Non-hijack: Today it was about 84F on my drive home. I was in between 186-192 at about 65mph with the higher end reading showing while on an incline on freeway. I have 35" tires and I recently replaced the fan clutch with a blue Aisin from Amazon and added 10k oil. Also replaced thermostat with OEM.

My temps were at least a few degrees higher or more before these changes. Radiator is aftermarket aluminum. Hope this helps.

Push any one of the 4 buttons until it says ia

Also change the oil to something thicker and try the mod for the fan clutch

I think boiling is 250ish?

But you loose your ac at 227 not fun in the summer.

AC is goof for I think about a 7 degree bump in engine temps. If it stays around that 202 mark with AC on you are in ok shape.

For the 96s and 97s, you can buy a little dongle for the OBDII port that'll read the coolant temp to your phone. You can spend between $30 and $120. I have an example of both (one bluetooth, one wifi) and don't notice any difference in performance.

I don't have a real read on my 80 temp yet. I know it sits at 187 driving around town.

I think I paid $13 for mine. Thing is awesome.

On a 95-100* day stop and go traffic no ac I will see about 195 or so. With the ac on it has gone as high as 206. On the freeway ac on it way sit at about 190-195.
I have a modded eaton clutch fan with 20k oil.

I'd freak out if I ever saw my oil pressure gauge go that low - mine is very happy right near the tippity-top line (grant it I know the one in th ephoto is normal range per manual). As accurate and precise as the coolant temp gauge and EPA 16 MPG on the sticker.

I would freak if it was at the top. Lol

First "hot" day today. About 90 degrees. In town. I let it idle while I went in to a customer's home for what was planned to be a few minutes. An hour later I got in my ice cold 80 and the temp gauge read 190. That's the highest I've ever seen it. Full sun. 90 degrees. Idling.

Outside temp 119

Engine temp 222

No AC after 220
