ect vs. eot

[scha0786]

is ect of 174 and an eot of 183 acceptable? air temp was 30 all temps in F

thanks

no, it seems like your thermostat is stuck open, both temps should be in the 190's

[scha0786]

is that going to hurt anything? leaving for wy on sat. should i replace the t=stat before then

[pizza pig]

no It shouldn't, i've been too busy the past 12k miles to do mine, mines stuck open as well. The truck just wont get up to operating temps, it'll be less efficient on mileage too Ive heard some say, but i haven't noticed a difference at all and we've had an absolutely crazy winter.

You should be fine

[scha0786]

well thats good news....I'll probably end up replacing it this week cause I have time....I guess this would explain why my heat output all winter has been lacking.

[pizza pig]

My heat has been fine all winter

Do you think I would be alright to drive out west with the thermostat like that?

[scha0786]

called boyer truck service and the service manager talked with two diesel techs.

Both agreed that 174F is little low on the temp. One tech said to replace stat to get a little warmer temp while the other tech said it is fine. Both didn't really seem like it was a big deal.

And both said my EOT was acceptable.

Got a price qoute to replace stat ($198.17) out the door!

I'll be tackling this myself tomorrow night, let you know what my temps are after that.

Expect your EOT to rise up to near or just over 200. You may have a slightly clogged oil cooler. Keep an eye on it.

I hope not, just picked up the thermostat from ford.

$22.00 out the door. plan on swapping it out tonight.
