Running hot
 

Added 90 hp injectors along with throttle plate to my 98 2500 5 SPF. Have plenty of power pulling 10k on gooseneck, but runs hot pulling. 4 core radiator,4:04 rears. What can I do to help cooling ?

Either add more air into the cylinders to help pull more cooler air, adjust timing so you are not burning so much diesel unburnt fuel equals more heat. Id you can ad your mods to your signature so we know what ya got.:c:

Do you have guages?

Just stock gauges. Was pulling same hills with same load,no problem. Installed 90 hp injectors,now the heating starts. Gauge gets up to 190-200 then in seconds,buzzer sounds,gauge pegs. Drop down to 3rd gear,crawl to the top of grade.

do you have a temp cycling thermostat if u do it will heat up to almost the red zone and drop back down. try looking into a non temp cycling thermostat

u need an egt guage before u melt a piston.
