Hi all Im new here and Have been reading threads for the past few hours and cant seem to find a list of answers. I have a 04 f250 Its Studded and those were put on around 90k miles ago (180k on the truck), EGR Delete, Has a coolant filter I installed AFTER flushing the cooling system. Im still puking coolant out the Degas bottle and the Heater hardly works. When Im running the truck around town i'll monitor it and it'll settle at around 176 degrees and the oil temp will be around 184 or so. Its rarely get past 10 degrees of each other So im thinking that rules out a bad Oil cooler. I can really really get on it (Running a SCT Extreme street tune) and the truck wont get hot. The truck actually cools off at while Idling. So to put in a list here is what Im experiencing
-Heater cools off at Idle
-Only warms up when I rev it up
-EOT and ECT are within 10 degrees of each other when I reach Operating temps
-I filled the DEGAS Bottle today and that Kinda helped the heater situation, even though it took around a gallon of fluid it was still puking coolant before then.
-I over filled the DEGAS a little today so some puking is expected.
Could it be something as simple as the DEGAS bottle cap? I put a new For one on there around 6 months ago and when I go to take it off, even if it's cooled off for a few hours it still lets off a bit of pressure and whistles at me.
Or could it be something as air in the system that causing it to burp and the heater to not work correctly?
Im sorry if when I typed this out its difficult to follow.
-I have the stock DEGAS bottle could I just have the coolant way over filled? even though I added nearly a gallon of coolant it's never over heated, but the heater not workin is something new that's seem to have happened.
Thanks in advance for the help guys, ive been thinkin about this all day lol.
