I got a 04.5 cummins with 109k im having temp problems with it... The truck is mainly stock it has an edge 3stage 40, 60, 90horsepower and a performance muffler. but my problem is the temp I do alot of work with it hauling cattle and farm epuipment and my dad pulls a 32ft 5th wheel. The truck doesnt run hot until it gets a load on it... any suggestions please let me know.. what can i do to fix the problem. I also have a 98.5 cummins that im having some heat issues with to it has afe cold air intake 4in straight pipe waste gate closed and the only time it gets hot is when i load it with 17 round bales of hay. any suggestions let me know please.

 

what temp is it running? Serviced the cooling system lately?

 

X2 on the cooling system

 

I havnt serviced the cooling system but I have replaced the thermostat.

 

try flushing the coolant system. also, what temps this thing running? keep in mind that under sustained heavy loads, itll run a lot hotter then normal, our completely stock 99 that we use for towing runs about 170 degrees empty but with a fully loaded 26 ft cattle trailer or the camper, itll run about 200-205 @ highway speeds

 

My 98.5 runs about 190 which is its normal running temp but when i get it loaded it runs between 205 and 215... jus depends on the load. but is it going to hurt it running that temp? I was just worried because when it gets that hot i dont want to mess something up.

My dads 04.5 runs 200 at its normal temp and when its loaded it runs about 205 to 210 is that bad?

 

Its warm take a blow gun and blow out your radaitor its maybe clogged, i blow mine out ever other service, running hay around and other stuff it gets clogged fast mine get 205 pushing and 190 around town, flush the cooling system

 

i agree, flush the cooling system good. but 215 is border line, the question is if it stays up there or does it just spike for a little bit and then come down? it wont hurt it right away, but prolonged runs in that temp could. I would flush the crap out of it, new t-stat and see what happens. course my 99 with 150hp injectors runs hot unloaded anyway, 195ish even with a new radiator and coolant. but thats with a 450hp plus truck on stock turbo. totally different then our towing rig though

dumb question, whats the ambient temp outside when it hits 215?

 

I changed the thermostat yesterday and it seems to not take as long to warm up. and i wash the radiator out about once a week when hauling hay... when i get the time im going to flush it out and go from there.. Um the temp outside when it gets that hot is anywhere from 90 to 98 prolly.. but when it heats up i let off and it will cool down to about 200 but im affraid if i dont do something one day its not going to cool off and blow up or something.

Since things are kinda slow for me right now im going to do some work to it. I was driving it last nIght testing the new thermostat and the idler pully went out on me so i gota get that fixed. and on top that I have got to pull the transmission saturday so it can be rebuilt.. I hope to have it all straight before hay season starts.

 

Blowing out the radiator helps washing with water hose is good also but high pressure water like from a car wash works the best but be careful not to damage the fins on the a/c cond.
