Towing temps too high help

[lovndcummins]

I have towed several time with my 2001 7.3 "X" same load same trailer. This week-end thou she got hot trans and engine. I don't have money for fancy gauges, so these reads are off the factory gauges only. Trans got up to just a hair before yellow, and eng temp shot up to about the same hair before max. Is there a better coolant I can be running (I have the green stuff)? Or anything else I can do to insure safe temps?

i plan on changing coolants i run the green crap also. i did a search and found a bunch of good topics about coolant for the 7.3. i dont know how to post links but just type 7.3 coolant and lots of great info comes up about coolant and they rite way to flush the system

sorry i couldnt be of much help.

any shifting problems or trans trouble codes? a slipping trans could cause higher than normal on both. I doubt a different coolant will cure your problem.

dont believe that stock gauge. get a trans gauge. You can get an autometer for about $60. How heavy was the load? You should also look into a 6.0 trans cooler. the stock 7.3 is a joke.

A $200 dollar gauge might be worth it as an alternative to a $2000 shop bill...just sayin. The guys on this board made me a believer, and I've never had a hiccup w/my rig...don't plan on having one, either...but at least I'll know when trouble's comin' before it's too late.

Nope no shift problems, or codes that I know of.

Your 2002 might have had gold stuff in there before and if you mix the green and the gold...it doesn't come out pretty. At minimum I would flush the coolant, replace the thermostat and flush the trans.

DIY trans flush...works great!
