Idle temperature?

[aod92]

What temps are you guys getting too after idling for a few minutes? My truck stays around 180 while driving and about 220 when idling. It seems like my electric fan isn't keeping up. Is that too warm or is that a normal temp when not moving?

Mine runs 175-185 all the time..what size cfm fan are you running? I've got dual fans on mine and when idling both run..fan 1 comes on at 175 and fan 2 comes on at 185..what truck is the engine in? Have you had it running long? Did you get all the air out of the engine?

I've had it running about 2 months now. All the air is out. It's a 6.0 lq4. The dual fans are EBay fans and are supposed to be 1400 cfm each. Not sure if they really are. I need to tune my fans to come on sooner too. They don't turn on until about 210.

If they don't come on til 210 that may be it..what thermostat do you have?

In traffic with a stock stat I idle around184-190. On a 102* on an asphalt lot I saw 214 while still, but cooled immediately under movement.

160 t-stat

Mine seems to cool pretty quick while driving too. That's what makes me think the fan is either not powerful enough or it's coming on too late and it's harder to cool down.

Mines got a 160 tsat to..I think my fans are like 2600 cfm each..they told me to get the biggest fans i could fit and thats what i did..on the other side my 2013 gmc everday truck runs 210 all the time..

where do you guys check to see what temp it is? I'm running 2 fans its 102 today and I notice my gauge started to mark the half point. I've only been driving the truck a few days but its usually at the 1/4 point. I also seen something about air in the system. how does one bleed the air out? thank you

Some scanners will show you the temp the pcm is reading

[lowrodderchev]

those scanners aint cheap LOL I still haven't bought a code reader few people told me I should get one if I'm doing this swap

[mongocanfly]

Lowrodder..I assume you have a gauge that don't have numbers...i don't like em..hard to tell what ya got numerically..you need to get a temp number first then go from there..getting the air out of a ls engine is done simply by taking the top hose loose from radiator and filling the engine completely with coolant..that's how I did mine anyway..

[lowrodderchev]

yes sir no numbers just Cold and hot (75 chevy blazer) I filled mine up from heater hose to so I'm guessing I'm good. going to purchase a infrared thermo today and see were I'm at just wasn't sure if there's a certain spot to get a reading from.
