Intermittent overheating, AC blows warm

I have idled for almost two hours in 100 degree heat. Truck was around 190 degrees....

 

The coolant bypass valves are leaking on some trucks. It happened to mine. I would not have know it if a tech didn't find it when checking my trans fluid level.

 

It is an idiot gauge. My truck could be running hot as hell at 220 yet the gauge is still in the center

 

For what it’s worth, OP, I have to do this with my ‘94 Accord unless I’m on the highway.

I now have an excuse to be the sweaty guy everywhere I go

 

My 04 can blast AC in 118 degree weather (like what we had a few weeks ago) and motor temps stay at a normal 188-195 according to my ECU reader. Granted my AC doesn't blow a cold as it once did but probably just needs a recharge.

Anyhow yeah a new truck shouldn't be sensitive to the weather like that.

 

Agree

 

Ac is blowing coldish again, needle is almost center

 

Has weather cooled? Or you started moving? Might be a faulty tstat...id take it in tomorrow still and have them check it out

 

Roll down the windows and turn on the heater full with fan on high. Offers the coolant and additional source of heat exchange. Was a standard practice when I was a kid in the Antelope Valley.

 

whats the coolant overflow level at?

 

I have a 1st gen and live in Arizona where it's 115 in the summer (not even the highest it's been). It never goes past the middle

 

Traffic must be thinning.

 

Op must have gotten caught up in the over turned motor home on the 14 frwy. had 3 lanes shut down for hours.

 

As others stated, it's hotter with other vehicles sitting all around you.

any changes in the moving conditions.

I would be calling my dealership and asking a few questions. 1st being why did I have to sweat my ass off cause my AC basicly stopped working and the temp read H.

 

My 2004 blew much colder air than my 2016.

 

Yeah I need to get my AC looked at...sounds like Darth Vader sometimes so I think I've got a leak.

 

I just glt home guys. AC started working and temperatures remained balanced all of a sudden. Was still at a stand still when it started working again. Ill update further when the dealership tells me whats going on.

 

Hope it's a simple fix for you man.

 

If you are sitting still put the truck in neutral or park and rev the engine to 1500-2000 rpm. It will draw more air across the radiator and cool it down. Same principle as high idling a diesel in a over the road truck. Draws more air and circulates the coolant faster. And for the record the pic you posted you are still in the normal operating range. Just on the high end of it.

 

Sounds like a faulty thermostat.
