Question to everyone out there with the 6.5 .... what sort of temps are you running. With the old ZD30 I would sit at 90 to 92 degrees and it would be rock solid. I am finding with the 6.5 that driving around town I am typically sitting in the mid 80's, but the slightest hill, or if off road when in low going up a relatively steep hill I am going over the 100 to 110 mark.

I am sure that the engine has no issues with this but with the mother of a radiator that BD put in, I am amazed that the temps seem to go up so high. Is this the norm??

Kindest regards

G'day Rainsey,
Those temps were the norm for me, last summer pre GM-ACDelco TS's. Can't advise true tests for another few months sorry.
Having owned a 3.0L Trol also, not sure if comparing temps is going to help you sleep old mate. Top query for all, I certainly haven't worked it out yet either. Cooling of modified truck/donks has huge questions and each and everysetup appears to be different:

1) Do you have grill/radiator free flow, and or giant spotty's like I had with a wind blocking BBQ plate bulbar also?

2) What temp thermostats did they install and what is your climate now ?

3) Was it fitted out with an oil cooler, where'sabouts and guesstimated size?

4) Is yours a 'V' belt or 'Serpentine' , water pumps differ I have read ?

5) Without scrolling back here, I believe you have a turbo too (lucky bugger) although how close does the 'V8' crossover pipe come to the sump maybe?

6) I'm running out of theory's:-)

Cheers Mb
