Overheating after Thermostat Change out
I got the impression from your 1st post that the T-stat change was routine maintenance that backfired on you. Was the new water pump identical to the old one? Fins facing same direction etc...?? Can you get a true temp reading with a thermometer for us?
Thermostat was changed just for the heck of updating (car would start running hot on medium trips 30miles+). Worst mistake ever.
I would believe it to of been the original or at least last replaced before 1984 when my Gpa parked the car.
After a few returns to the auto store I got a 180 that opened at the right temp yet still overheating.
Next logical step I thought was the water pump. Changed it real easy for someone with no prior experience. No leaking. good seal. Matched 110%. Noticed lots of tan calcium looking gunk (Rust?) in the engine block ports while changing it though (not blocking, just if I stuck my finger in the holes residue from the bottom)
Still overheating.
While trying to burp air from the lines after the Water pump change I notice there wasn't any movement in the fluid in my radiator.
One would think there would of been some movement in all the fluid I lost from the Water pump change.
Overheating.
Now. Not a blown head gasket. I had No trace of oil in my rad fluid.
This would lead me to believe that my Bottom hose or radiator is clogged with junk (assumption piecing the tan stuff in the block and looking into the radiator top)
SO. All along I think maybe my Radiator (Original one, never been flushed sat for years) is possibly clogged down by the Bottom hose.
ALSO noticed. Bottom hose was Ice cold by the radiator but Unable to touch HOT up by the water pump.
Still haven't purchased a thermogun to check temps.
Something is up because the radiator pukes after runs. - Another thing that leads me to think clog.
Added some Radiator seal a month prior to fix a small drip - Another thing that leads me to think clog.
What do you think?
