Tons of problems, not sure if they're related or just bad luck.

I bought an 08 in June that had 84,000 miles on it, and since then I've had nothing but trouble and I'm considering getting rid of it for another F250. The main reason I'm posting this is to see if anyone can see a pattern or if it's all just coincidence. The problems started 4 days after I drove it off the lot, and I haven't even put 8,000 miles on it yet.

1) Replaced Oil Cooler. 2nd time this has been replaced. The first time was 10,000 miles before I bought it.

2) Replaced Radiator. Happened 3 weeks after the oil cooler.

3) Replaced heater hoses and some sort of heater valve. This has still not fixed my heater and I can only get heat if the temp setting is under 85 and I don't turn the fan up all the way.

4) Dealership is telling me the heater core is bad and needs to go for only $1500. I've decided not to replace the heater core at this time.

Any ideas on how these could be related? I've had several coolant flushes done and there doesn't seem to be any trash in the lines, but I don't really know what else to do. Is there another component that I need to look at next before something goes out?

everything you listed is coolant related. your oil cooler is plugged, maybe your heater core also. dont know about your rad.

get yourself a coolant filter and go from there or you will be replacing everything in a couple of months.

Any advice on brands?

Ya i would do a good flush and use some ec-1 rated coolant. I went with the diesel site coolant filter. So far so good

I recently had a flush done when my heater hoses were replaced, but I'm thinking they either forgot or just didn't do it right. In my past experience when a heater core goes bad you can smell the coolant. Is the filter something that I can do in my garage?

[04hdfatboy]

Yes the coolant filter is an easy install. Its possible they didnt do a good flush. I wanted it done right so i did it myself. Its a long process but worth it.

as far as coolant smell goes, you will only get that if its leaking in the cab. if its plugged, you will get less flow and no heat like you have.
