Having problems with your 1988 Ford F 250 ?

1989 Ford F250 Diesel is spiking to red in temp gauge

\015 I just purchased an 89 F250 diesel (new to me). Seemed to run fine - have run it uphill once or twice with no problem. Last week, ran uphill turned off, truck sat for 1/2 hour and then, going back downhill, engine light came on. Three miles or so later, temp gauge spiked from "normal" to redline. \015\012\015\012Have tried to duplicate the problem - letting truck run, running across town - with no success. Until today. Ran it across town (on the flats), guage was reading normal. Then ran it uphill - got less than 1/2 mile, was shifting from 3rd to 4th, I think - and the engine light came on and the gauge spiked red again.\015\012\015\012I have fluid, the truck is not leaking fluids, and the truck is not overheating, in the conventional sense (steam and fluid flying everywhere).\015\012\015\012PLEASE HELP? This is very frustrating, as I live in the moutains and not going uphill is not an option...\015 Posted / edited by AnonymousUser on : 20-05-2019

Just take it to autozone or just about any autoparts stores, they will check your code for free, then you will know what you need.
Normalle a vehicule that goes in the red like ours idle or running slow is ok the radiator is not cooling that big engine enough just good for slow speed im sure if the faster you go the hotter or going uphill or pulling something heavy the radiator is not doing is job our asking more from the engine and the engine need more cooling radiator not good= overheat redline hope it make sense to you thank you pierre p.s l dont like to say like that but like toddg say our not been spoiled by expert here so let me know
