Hi Folks - I'm at a bit of a loss on this one... Hoping you might have some insight to share.
2004 Ram1500, 5.7L 4x4.
Here's the story and symptoms -
Temperature gauge reads good while driving. Slowly wavers a bit around the midpoint on the gauge. But when idling, it creeps up towards the red line. !!!
Less than adequate heat coming from the interior vents.
Getting a cylinder 5 misfire code periodically...
Losing a bit of coolant very very slowly, but can't find a physical leak.
I felt as though I might have a small head or gasket leak, so I treated it with this stuff https://rislone.com/ca/wp-content/uploads/2018/09/31136-PDS.pdf
Also changed thermostat... with 203 deg.
Top Rad Hose from stat is quite hot. Lower Rad hose is quite cold. Rad itself seems quite cold. Fairly certain it's not getting warm enough to engage the fan-clutch.
Parked Truck on incline and went through several cycles of heat-cool-squeeze hoses-start-stop-rev up, etc.. to burp.
Rad is not plugged... I can easily move coolant back and forth through it, when squeezing top hose.
There is no bubbling in reservoir..
No Steam from tailpipe.
Nothing has changed. All symptoms are the same as above.
I read somewhere that there is an air vent port plug somewhere....(removable with allen wrench) but I'll be darned if I can find it... Any help pointing me to it would be great...
I could be wrong, but it seems like I have poor circulation. (if any?)
Pump Problem?? I've changed a few water pumps in other vehicles over the years... typically because they started leaking through the seal.... Not the case this time... Is there a chance that a coolant pump would just stop pumping?? Impeller spun off shaft? I think it's likely the 2004 original pump. Doesn't look like an easy job to replace. I'd like to exhaust other options or prove it somehow before I go tearing into the pump.
Any and all advice will be greatly appreciated....
Thanks Folks,
Wayne
