Avg coolant temp 6.9

[JAKRANCH]

I have an aftermarket coolant gauge. I have to run the truck really hard to get temps above 160. Is this a fairly average temp? Truck is t19 3.55s banks power pack. I can see it being normal just wanted to ask.

Normal temperature should be around 190. I bet your t-stat is stuck open.

Mine runs at 190* also with aftermarket gauge

Either thermostat is stuck open or your gauge is off. Where do you have the sender?

 

[Hydro-idi]

190 is where they should all be sitting during normal operation.

The stat starts to open @192. If lightly loaded it should be near this. The stat is fully open @212. Its not uncommon for a working engine to hit 220-230.

But remeber, unloaded cruising is not "working the engine", especially if your timijg is good and the engine's not using a lot of fuel to maintain speed.

Temps should be in the 180-195 range and stay there. If it quickly climbs to 160(within 10 mins of driving) and stays there..chances are your gauge may be reading low.

If it's slow to climb and varies quite a bit... thermostat, most likely.

Hmm well it is a slow climb and then it is steady. Stock gauge looks normal ..... I mean it is within acceptable range. Ill have to see where the sender is mounted. Is there a way to check t stat see if its bad?

My thermostat was stuck open on my truck, I ran at 160-170 all day. Changed thermostat now sit at 190 all day idling or driving. Warm or cold outside

motorcraft thermostat only if you change it. I am a firm believer in oem solves problems, especially when it comes to thermostats. IMO it doesnt matter if it is a honda or a interantional oem thermostats make them happy.

 

[JAKRANCH]

Ok just got done ordering motocraft t stat

"...a way to check t stat see if its bad?..."
I like bowl of hot H2O & thermometer, throw it in & watch 4 opening/closing

Even idling are your trucks maintaining 180?

 

[03wr250f]

mine idling, not even on high idle will over about 10-20 minutes make its way up to 190* depending on outside air temp

 

[Fordfan90]

Mine gets to 180 but once idling it starts going back down to 140.
