Yes, if the new rad does not fix it then the 4 core is fine.

Well not like I am going back to it. I will keep it since it has 6000 miles on it and someone with ac I'm sure would be fine with it.

Doesn't sound right. My money is on head gaskets and this is just the start of the longest overheat thread ever.

I have gone thru most of the threads on radiators on here and some on head gaskets and I don't think I have a head gasket issue. There is not one thing that points to that. Truck never overheats, just gets warm on long climbs. When I got the radiator I thought 4 core would be better but when you take into account that the radiator itself isn't larger and all you are doing is making the cores smaller it seems to make more sense. Now if I got a high flow water pump it would have compensated for moving the water through the smaller cores.

My shop didn't really know what to do. They also work on Mark's truck and our trucks are set up exactly the same except he has a original radiator.

A guy who sets up racing BMWs was in the shop and was looking at my car and he brought up the issue with four core radiators and how he sees the issue in race cars all the time. Remember I only have this problem when I am sitting on a hill. With gravity and the four core the water pump isn't moving fast enough. To me it makes sense but until the truck comes back and I can test it who knows. I know the new t stat fixed half the issue.

Because its generating excess heat that the system can't cool. The heat has to come from somewhere. A tiny head gasket leak could inject that heat ...

Everyone else I assuming that the problem is inadequate cooling. I'm suggesting excess heat. And there is a difference.

I could detect neither on mine ... But when I took the head off I found leakage between a cylinder and waterway.

Started as occasional over heating ...then became loss of cooling water. I could never detect gas in the water.

Nothing is easy. Of course my oil lines won't work with the new radiator. Fixed vs not fixed fittings. Need to see if Eric has adapters. My oil lines are Eric's first design before they became red and blue.

Except I have never lost coolant and I don't over heat. I run hot sitting on an angle. After replacing the tstat I don't run hot climbing.

Did you ever have coolant leak from the coolant reservoir overflow tube (in the fender well)? I have had a similar symptoms to what you're saying, except I have on two separate occasions had a pretty significant coolant leak from this overflow tube when my truck has been running for a while and I put it in park/shut it down. I've never noticed it while in motion and have had my wife drive behind to see if any fluids splattered on her car. Same situation though, shop can't find any issue. I've replaced water pump, no head gasket replacement and no radiator replacement as far as I know.

Aren't you loosing coolant? Sounds like your system is over pressurized.

You either have a faulty radiator cap or have a head gasket leak.

Yes, I'm losing coolant, it's not quite like a gusher, but I'm certainly losing fluid.

------ Follow up post added October 25th, 2012 09:55 PM ------

What's a fair price for parts/labor to replace a head gasket?

My shop quoted me 1800 with a valve job.
