over heating

[smokin dually]

I am working on a 95 F350. I replaced the oil cooler about 3 weeks ago. After 3 days of driving it started over heating. I have already replaced the the t-stat. I let it run for about 45 minutes and the heat hand never got over half way. Both radiator hoses got warm half way to the radiator but the radiator never got hot. The heater hoses were very hot. Does this sound like a clogged radiator or maybe a clogged oil cooler. Any help is appreciated.

not to judge your ability but did you put the t-stat in upside down. That will really cause problems...i assume that if you changed the oil cooler you know what you are doing. Are you talking about the oil cooler on the side of the engine. Water pump could be toast too but im not really sure how to test it...did you pressure test the system after you changed the t-stat...if there is a pressure leak then the truck will over heat because by pressurizing the system it lowers the boiling point of the coolant...Hows the radiator cap if that is bad then you can have problems too. Just some thoughts.

I had the radiator flushed. The guy said it was clogged up, so I will see if this fixes the problem tomorrow.

I ran the truck this morning and it does the same thing. After about 20 minutes of driving the trucks gets hot. The radiator hoses still only get warm about half way up. The heater hoses are still too hot to touch. The radiator is still cold as well. The water pump does not make any abnormal noises, but is the only thing that has not been changed. Please help I am at a lose and out of ideas.

about two months ago ,i had a water pump that the fins were spinning on the shaft not flowing coolant , if engine is getting hot and radiator is staing for the most part cool ,sounds like a flow issue

I pulled the water pump off this morning and it looks perfect, no play at all. I was wondering if a clogged oil cooler could cause this problem. I thought that the coolant flowed though the the block then into the oil cooler, but after looking at the casting of the front cover, it looks like it goes though the oil cooler first then into the block.

i thought you had replaced oil cooler already
