Coolant temp

Pwrcummins · Mar 28, 2014

Ok so I haven't gone around to getting my fan clutch replaced yet. Driving today I hear my fan roaring. Iv never heard that before. So that tells me my fan clutch is working. Could there be something else heating me up?

I'm bout done with this truck. I can't have a vehicle that doesn't get hot. I want to fix it but funds are tight. Is there an easy was to pull the radiator and maybe I can fix the fins on it? Will plugging in my egr valve make the fan work 100%? I know Iv prolly asked the same question earlier I'm just stressed with this issue.

Your radiator is possibly clogged. Can you. Measure the inlet and outlet temp?

Temp gun at both hoses. If there is a huge difference, iirc 20* or more, there is a flow issue

Ok I'll give that a shot

Well no flow issue. The pressure in the hoses are firm. Both feel the same temp. Don't have a temp gun unfortunately.

The fact that coolant temp was reading 30 degrees hotter than ambient temp and 20 hotter than oil after sitting over night makes me wonder if the coolant temp sensor isn't reading hot.
