Need some advice

[versitek]

I have the same old colant loss as most, and I am done messing with it!!!
My truck is a Job1 550 cc 4x4 with 200" wb. I have 75,000 miles on her, 65,000 of that with the spartan 250hp and 10,000 of the 65 with the TCM 250 tune. Now 90% of all miles on the truck are towing miles.(combind weight of truck and trailer is just under 40,000lbs)

I did have the leaking stock (3 rads, 2 lower 1 upper rad hoses and god knows what else) I am done with dealers! It is cheaper to fix it myself!

What should I all do to this truck with in reason knowing what I use it for!
1 headstuds and gaskets
2 egr delete
3 tq converter
I also have the airdog lift pump on now!
Any help would be great
Thanks Stan

If the EGR coolers are OK,
A tune will keep the EGR closed except at an idle, so that is an easy fix.. Closed there is no hot gas going through, but if you are going to pull the cab to do HG, probably kiss the coolers and EGR goodbye.

IMO: This is a really good engine, with only the emission control niggles... If it is HG, and you are going that far with it, Studs are probably a good idea while it is torn down anyway...

The lower end, with a (bed plate) split block to support the crank makes for a strong truck. You are asking a lot at 40,000 lbs and a big tune, over 500 HP... I might do it, and do the whole Enchilada. Face it, there is really no other truck in that Class..

I have an F-450 with a ten Metric ton so about 12 ton hitch, and air brakes added over hydraulic, for all the same reasons. There is no other truck with a luxury cab in this Class..

I would go the whole Enchilada.... But that is me...

You need to for sure get the coolers off the truck. I would do the gaskets and studs also. Wait on the Dirty Diesel wastegate kit. It should be a lot cheaper than the Elite. Their cooler removal kit is only $400.

I think it is just the cooler, but I dont want to take the chance if it has taken the gaskets allready. At idle she realy likes to smoke at times.

Is it ok to reroute the coolant from the coolers to see if it is the problem or will that cause other problems?
I will lose about a gallon of coolant in less then 5,000 miles! It will also lose some just sitting
