2008 Ranger, 2WD, 3.0 liter 6 cylinder.
90K miles.
So, I followed coolant flush directions from chrisfix on youtube who is pretty good, he's got like 10 mil subs.
I:
1) Drained the radiator and reservoir.
2) Filled radiator with just distilled and drove about 30 mins with heater on (heat was really hot). Noticed some dripping from radiator after parking and couldn't trace location.
3) drained and refilled with coolant flush + distilled. Drove for 3-6 hours as per flush label, with heater on often (also used AC sometimes because it got really hot in the truck). Noticed some leaking again when parked and cold engine radiator level was down a couple inches and not much left in reservoir.
4) Drained and REMOVED THE THERMOSTAT. Refilled with just distilled.
5) Idled for 10 minutes with heater on thinking it'd be enough to get temperature gauge %50 but it only ever got about %20 instead of in the middle. So I drove it about 30 minutes with heat on but heat wasn't that hot and gauge still only got to about %20.
6) Parked and noticed AC accumulator was cold and condensation despite didn't use the AC. Noticed about 1-2 cups of water leaking from where seems to be the AC Evaporator. (as shown in photo the circled area it seems to be coming from).
Figured it was running hot/high pressure and busted some sorta seal, so I figured I'll finish the flush process until the water drains clear, fill with 50/50 coolant/water so I can actually drive for work etc, and then I'll try and find the leak problem and reuse the 50/50 if I have to drain it all to fix/replace parts.
7) drained that round of water and refilled again with distilled and drove about 15 mins with heat on and same thing happens, only %20 temp gauge and heater not that hot. Check Engine pops up P0128 COOLANT THERMOSTAT ) COOLANT TEMPERATURE BELOW THERMOSTAT REGULATING TEMPERATURE).
8) drained that round of water and now wondering what to do.
Someone said it's because the engine is running too cold because the thermostat was removed and not keeping the water in one area to heat it up long enough, that the radiator heatsink grill and fan is cooling it down too much.
I'm hoping the 1-2 cups water leaked from where seems to be the Evaporator is some sort of pressure release valve or something but IDK. If I have to replace parts I will.
I guess now I'll reinstall the thermostat, and keep filling and draining distilled water until it runs clear, using the heater on and off while driving about 10-15 minutes between rounds. And then refill with 50/50.
THANK YOU
