“Dylan’s” 89. Back at it!

[Abusfullofnuns]

I don't have all those options b/c I don't have a pressure sensor wired in. The sensor is disabled in hp tuner, so I'd have to guess that's why I don't have the same settings available. I was a couple degrees off earlier in my description.

The fan runs when the a/c clutch is engaged, but the harness was originally done by speartech. Fan #2 is set up as serial cycling when a/c is on and has tps and rpm limits set.

What is that ignition off temp?

I’m gonna make a post in the garage and see if we have any HPtuner experts

 

[nvrenuf]

Any luck with the fans / overheating issue?

 

[chris85]

He’s coming this afternoon to make the changes. Hope that does the trick!

 

[chris85]

Ok. We got the fans to come on. But it’s still getting hot at idle. He noticed before ever cranking that the sensor was reading 140. The truck sits out in the sun right now but I wouldn’t think it would be that hot just sitting. The saga continues

Turns out the fan 2 fuse just had a bad connection but we still changed some parameters.

Sounds like you need independent verification...

Translation?

 

[Fastereddie]

That’s gotta be inaccurate. I’m in vegas and my truck bakes in the 110* sun all day and the “cold” temps are between 112-117. Trans temp, coolant, oil temp etc... all within a degree or two.

Separate temp gauge or IR temp gun versus the sensor reading

 

[Abusfullofnuns]

Dash matches laptop? How about tempmof radiator
In and out?

Also agree that it’s not 140F at rest.

 

[chris85]

Ahh! Yeah I meant to get a IR gun.

 

[Fastereddie]

Separate temp gauge or IR temp gun versus the sensor reading

I vote separate gauge. I find ir not very accurate for determining coolant temp. It is good at finding temp differences but not actual number. At least in my experience.

 

[chris85]

So trans temp reads 80 at rest. Definitely a discrepancy.

Dash matches laptop? How about tempmof radiator
In and out?

Also agree that it’s not 140F at rest.

Both read from the OBD II so yeah they match. The temp sensor came with the Dakota Digital gauges.

 

[Fastereddie]

Just to make it more cunfusled, the LT swap we just did has a summit electric gauge and it almost exactly matches the ect reading up to 180. After that it skews off. 210 on the gauge = 189 ect.

 

[Fastereddie]

Maybe you have a ground offset.

 

[chris85]

So where could I put another sensor?

 

[Abusfullofnuns]

I plugged a port on passenger side block when I went to Dakota digital. If I remember right, it has a funky size. 12mm or something. Not a common size but one of the cheapy gauges at the auto parts store had an adapter that size. If I remember right, I ended up cutting down a bolt and usiing a brass crush washer.

 

[Fastereddie]

You could always try one of those radiator caps with a thermometer in it...

 

[Fastereddie]

I put our sensor here in the block.

 

[Justin V]

I argue the other way.

IR lets you check anywhere throughout the system which is good for finding potential problems clogs in heater cores or radiators. You do have to be careful because certain surfaces will give a false reading. Painted things, rubber, polished things and more can throw a false reading.

Plus they are useful for so many other things.
