truck was sitting for a couple years, it needed a new e4od trans which I just finished replacing this summer, As well as disassembling, ultrasonic cleaning, and pop testing my injectors, and replacing the return line system. It is now running nicely.
EDIT: I also have an isspro trans temp sensor/gauge, that I installed alongside the new trans. After 30 minutes of driving or so it will report about 115-120 degree, which is still VERY cold for the e4od. It never gets above this temp, although I have only driven about 120 miles so far, since getting it back up and running.
I am going through everything little by little, my current issue is that I have barely any heat from the defrost.
I replaced the thermostat with a Motorcraft RT1049 / E5TZ-8575-C, I figured might as well because I had no idea what the previous owner had in there, what came out appears to be a china copy the Motorcraft, it was much shorter in total height. I also installed a new radiator cap because the rubber seals were dry rotted and cracked on the old one.
I still just barely have heat from the defrost, if its 60 degree outside, then the heat feels maybe 65-70? just barely warmer is all.
I hooked up my garden hose to one side of the heater core, and unhooked the other side, when I turn the garden hose on I get a full flow from the heater core, so it does not appear to be plugged up.
I use my infrared thermostat to check the the thermostat neck, water pump, and the upper and lower radiator tanks.
The thermostat neck, water pump, and upper tank read about 138 degree. the lower radiator tank reads about 70 degree.
so the bottom of the radiator is waaaaaay colder, I drained a little bit from the radiator and looked into the top tank through the radiator cap hole, it looks a little bit gunky, but all the rows/holes are visible, none of the holes appear blocked off entirely.
My next test was to shut the truck off and see what the temps do. once I shut the truck off the temp at the thermostat housing and water pump went up until around 185 degree.....
so that tells me that the engine is much cooler while running, so I am suspecting the clutch fan. I do think I can hear it while driving, and it seems to be pushing a good amount of air at idle..... I have heard one that is fully locked up before and mine is not quite that loud, but its also louder than normal *i think*
I have seen plenty of posts that say DO NOT try to stop that fan with anything.... so I don't plan to.
just wish I could know for sure if its the fan clutch, if it were a plugged up radiator then it wouldn't stay so cool at the thermostat housing and water pump while running would it?
I would kinda think that even with the fan clutch running the fan way more than it should, that the thermostat would still get the truck to operating temperature, but maybe not? can an overactive fan clutch really stop these trucks from reaching operating temperature?
