Should we wait till a 15degree delta to change cooler?

[Hardline]

I have an 04 F550 that weights about 14,000 lbs. at cruising speeds of 65 it will bounce around 10-13 degrees.

This truck has 4.88 gears and weights a little more than a pickup so are the deltas at a point that I should go ahead with the cooler now or wait till I see 15 degrees? Thanks JJ

I would flush and switch to elc and get a coolant filter. 500 miles later change oil cooler AND EGR cooler because it is just a matter of time.

How many miles on your truck?

[osue077]

The sig say 193k

I agree with changing over to ELC and a coolant filter is one of the best investments you will ever make.

I cant find any writeups about how to change your oil and egr coolers. Is this a big job or something we can do at home without much of a problem?

Flush it change it and add a coolant filter JJ

It is a big job, but something that you can do at home. Just take your time-it will take a full weekend even if you have everything lined up and ready to go.

Sorry I guess I should have included a little more information. I have had a coolant filter for about the last 20K miles. I did the VC-9 flush, restore flush, distilled flushes and then the distilled and ELC 2 weekends ago. Did not get any changes in the delta so I was wondering if the 10-12 delta was at the do it now point or if I should wait till I get to the 15 degree. My plan is to install a EGR cooler that has the ends welded up and a factory oil cooler.

This engine was replaced at 65K so if this next cooler will get the truck to last another 130K esp with the ELC in there that will get it to the 300K mile mark and that is what I think the life span of me having this truck.

i see you guys are talking about coolant filter and some other stuff, do you have to worry about these things if you have the egr delete on the truck??
