I've had a temp problem with my jeep almost as long as I've owned it. I thought I fixed it when I found my water pump impeller completely rusted off. When I replaced the water pump, I also replaced the radiator, and thermostat. The thermostat is 185 degrees. I know a lot of you say the 185 is a waste but I ought it before I knew about the water pump. Since those 3 items were replaced, I've had no problems. This weekend I made a far drive and I had some problems. While running 70-75 mph at 2000-2200 Rpms, the engine slowly starts to gain temperature to the point you will have to pull over. As long as I'm below those speeds and Rpms I'm fine. This is pretty mind boggling to me. Anybody have any ideas?

I wonder how much rust is still in the block if the cooling system was so bad the water pump impellers rusted off.

If you own a Renix Jeep, you'll want to check this out.

While I had everything apart, I did my best to pump as much rust out as possible. I feel like I did a pretty good job but who knows

It would be cool if ou could pull one or two of the block drain plugs.

Sorta. On the driver's side behind the exhaust manifold. Pipe plugs with a 5/16" square drive. A ***** to get out. I had a really rusty block and I flushed it on an engine stand. Without removing those plugs I neveer woulda gotten all the rust out.

Ill take a look at that when I get home later on. The strange thing is this only happens when I'm consistently running it. My 20 min drive home from work is just enough to get it just above 210. Any other time it pretty much stays at 185
