***ECT & EOT While Towing...

[rb12405]

Hey fellas. I'm on the road headed towards Hunting Island in SC, and have a golf cart alonh with our 30' travel trailer. Total wgt is estimated @ 7,500lbs. I am seeing deltas of 10 to 12 degrees (ECT: 200; EOT: 212) Is this normal? We run @ 65 to 70 mph. Also, I noticed up a long grade, my EOT started flashing red and hit 221 degrees. I recently switched to Rotella T6 with revx, and went to Zerex red ELC HD coolant. I am also running Matt @ gearheads 8k towing tune. I should also add that during normal driving while running matter SRL tune, the EOT is ~192 and the ECT is ~188. Thanks in advance.

Looks about the same temps my truck runs pulling a simalar load with the same tune

Your good to go. I wouldn't worry until it hit 230 and stayed there

Deltas don't matter when towing or going any faster then 60-65 mph... more stress= hotter oil.

not until they get over 230-240*

Your good to go

Ditto. If you only hit 221* after a long grade, I'd say you've got a pretty healthy cooling system at the moment

Not to hijack, but if you were unloaded at 75 then your deltas could be more than 15* and it would be ok?

When is the fan supposed to kick on for ECT?

[jetjock15]

fan kicks on soley based on ECT at 230, but there are many other variables and/or combination of variables that turn it on for other reasons.

You guys are funny with your temps. Try towing a 42' toyhauler with with an off road car in the back. Can't even tow level in the 220s. there is no "break point" at the numbers you list. They just fall into the extreme duty category- Talk to your ford dealer, even running constant 230-240 all the recommend action would be to increase your oil change interval. Truck starts to "prevent" heat issues from occuring by reducing power when you reach 250s, limp mode kicks in high 260s. Let her cool down, and she is ready to roll. Diesel equipment in Iraq runs 24/7 in the heat, constant 280 range, yes its different engines and all, but seals ect are all the same. Go to the track some time and see what the race engines run. mid 300s EOTs..... The level attention this issue gets with no real facts starts to get annoying after awhile, people seem to develop OCD on EOT and blame the 6.0 issues on it. 6.0 issues caused by faulty EGR components and overpowered tunes for heads, not to many directly related to high EOTs. But I digress...

Wouldn't you say his unloaded temps seem low? Doesn't the thermostat open at 193?
