Is everything ok? I just had an x-monitor, air box and new stage 1 injectors installed for 5th wheeling. I noticed after a short 10 trip (in 30 degree temps) that the truck warmed up a lot quicker and ran warmer....Meaning my water temp guage came up to 180 in the first 5 miles.... Normally it won't get off the low section of normal in this weather. Straight up on the guage is usually when I'm towing. Do larger injectors affect engine temperatures?

Love the x-monitor, but it's connected to the the transmission monitor wire at the PCM connector....Think that means it will always read about 40 degrees low. Sound right?

Next step is the TC and Valve body.....Could have vacationed in Europe for what I'm spending!

Yup! More fuel means more HP. More HP means more heat. Result is higher EGT's and towing heavy on a long grade can show up on the water temp also!

The dirty secret about adding more fuel, and towing up long grades at higher altitudes on hot days, is your radiator becomes the final limiting factor in how much power you're able to use. EGTs can be held in check, but you'l be boiling over. And as engine coolant temps go up, the amount of continuous high EGTs it can take goes down.

 

My water temp went up as well with my box and the Jammer 3's.

 

Well that makes me feel more at ease. I'll just be sure and do a good radiator flush before camping season starts.

try flushing it and also try running a different cap . cause the pound rating on the cap can make a diffence along with the thermostat.

 

You mean a cap with a higher temp? And a thermostat with a lower temp when it opens?

 

I just installed a set of 275's and my water temps have stayed the same.

 

I was looking at some of the Stanadyne wetting agent they make. Supposed to increase the coolants ability to transfer heat, easier transfer= sheds more heat. Anybody tried this stuff?

 

This stuff really works, use it in my hauler pulling 26k

Try putting in a new thermostat, 180 deg. There were a bunch of OEM thermostats that were bad to heat up on a pull.

 

Infidel, I meant red line on my last post, got CRS ya know. You say it works so I might give it a try. I haul 12 to 14K and it can get pretty warm in the desert. Any edge helps!!

 

THe blow by bottle may have contaminated the radiator restricting the air flow through it.

 

The wetting agents (surfactants) really work. They reduce the inherient surface tension of water that causes it to "bubble up". The result is more layered water contacting hot metal surfaces for better cooling.
Another way to cool down temp is to reduce the percentage of coolant (antifreeze) used in you radiator. Antifreeze does NOT help cooling...it is for anti freezing and anti corrosion. I would not go straight water, as racers do, but cutting back to 20-25% antifreeze in your radiator can help cool things down for summer traveling.

RJ, you are correct that antifreeze doesn't help with cooling... almost.
Anti-freeze raises the boiling point of water and will allow you to reach higher temps without boil over so in effect it does help with cooling.
