Sorry for the long post.
Dakota getting hot. here is the history
Late last fall had to fix a heater core that was stopped up.
Took off heater hoses and mixed 1 bottle CLR to gallon of water and poured in heater core.
Then water hose to wash out CLR mix. Then air hose.
Repeat until gallon of CLR was gone.
Reattach heater hoses.
Then Prestone Radiator Flush per directions on bottle.
Then flush until all clear. (Just found out about the block drain bolts a week ago)
New T-stat and filled with antifreeze.
No trouble out of heater or truck getting hot until about a month ago. When dash cluster had issues.
Month ago or so got hot. BOILING hot not a bad gauge or sending unit coolant
actually over flows the overflow jug.
I'd say now it's more water than antifreeze.
New 195 T-stat.
New pressure cap 16lbs
2 new clutches got at advance 90 day warrenty . thinking bout MAKING them get a better one for same price 50.00
FYI 10% discounts to Vets.
Was working OK after the 1st clutch fan. Then was a little late for a job and had to make up some time.
Running hard up steep grades then started getting hot. turn on heater again to cool down.
If I stay around 2000 RPM temp will stay about 210. limped home.
Changed clutch (to 2nd one) two weeks later and was OK on trip to another job was cool outside about 78 and stayed about 2000 RPM
Today running late high RPMs again and got hot. was about 90 0utside
I did notice at a red light it was about 240 so I revved engine and could not hear fan.
stopped for gas popped the hood and could feel the fan blow but not like (what I think) it should .
I don't think it is the water pump cause runnin the heater cools down the temp hand.
If it was the water pump not circulating water the heater blower wouldn't cool it down.
Don't think the radiator is stopped up but might be. Brother said the mechanics on the strip job he worked on would pour a box of cascade in the radiator of triple 7's and run them a shift to clean them out.
Dude at advance already said he would have to order another fan clutch if this one did not work.
Any ideals? I think it is the POS fan clutch from advance should have got it from Rock but had to have it yesterday.
