Heres a weird one... :dizzy:

3rd gear (o/d off) 70mph i saw my temp going up, hit around 230 according to OBD and torque before i backed it of. seemed good otherwise, average was around 212-220. Water pump was replaced last year, coolant flushed then, checked to see if the fan was OK as well.

Any thoughts? at what temp should i get worried when it hits?

Ive got 135k on the stock tstat so im thinking of changing that out in the not too distant future as a precaution (and replacing it with a 180 degree one if its available)

Could be thermostat

1st why are you doing 70mph in 3rd gear?

Changing the t-stat is a very good idea but will most likely not help,do not use a 180 degree t-stat as it will create more problems then solve.Could be a ECT sensor that's going bad or the bigger tires and stock gears.

Im not a mechanic, but going 70, your fan has nothing to do with it.


Thats a thermostat, radiator blockage either inside or clogged fins, maybe air in coolant..

Id start there.

I'd think running hot in third gear at 70 would be the cause. How many RPM's are you running at that speed, 3000? I get wary running mine over 2000, maybe I'm just a baby.

I run 3000rpm's at 70mph,granted I'm geared way lower also.

It's not the rpm's as 3000rpm's is really not that high but no point to do so when you got OD,unless your towing then keep OD locked out but keep the speeds down also.

Wow, ok. Must not get that great of mileage at 70 either. I have to use mine for work as well.
