overheating! - therefused - 13-06-2013
i am having overheating issues when im giving it some beans.
iv removed the thermostat to rule that out, opens fine though when i tested it.
normal running temp with no thermostat is 75degrees, runs perfectly fine.
problem is, as soon as i hit 100mph 5th gear 3.5-4k my engine temp flys from 80 straight upto 100degree's and beyond in a matter of seconds, and i mean litteraly seconds, it seriously overheats, heaters go scorching.
when i let off the throttle and drop my speed it cools back to 80degrees quite quickly.
could my fueling or wastegate adjustments be causing this??? or is it somthing more serious.
thanks for any help
tim

oh forgot say that my fuel is turned up 1 1/4 turns and my wastegate arm is all the way across at its shortest (dont know if it should be that far lol)
also theres a small arm on the back of my fuel pump, used to have a blue peice of plastic covering it, what does this arm do? i lenghned it a few turns but carnt say i noticed any differance.

Don't drive at 100mph and it will be fine

yeah ^^^^
(We dont mean to assume of course but we do assume you're doing this on a track or private road??)
fyi...know your pump and what to adjust before just trying something...like lengthening an arm

yeh its on a private road.
it shouldnt just go that hot tho should it? id have though it should sit at that happily, thats why i ask

What kind of condition is your radiator in? Mine used to get up to around 90* on a rag but never above it til the hg blew

Mine shoots up to 90 if i start working it...

i think iv cracked it, i had my wastewgate arm all the way across so where was no thread left, iv unscrewed it about halfway and theres much more power asnd it dosnt overheat. must have been runing super lean?

Odd. Very odd

You can't run a diesel lean
Heat in a diesel engine is from running excessively rich (billowing smoke)
