Overheating Problems

I own a 1999 Dodge Dakota. I am having overheating problems. I have a new water pump and t-stat. The temp goes up whenever anything but the heater is on. Once I turn the heater on the temp goes back down. The water is clean and so is the oil. There is a little foam in the water but that is it. I recently took it to a shop and they did a pressure check and lost no pressure. They did a block check and it was OK. They said nothing was wrong with my Head Gasket. I'm totally comfused.

[quote=gshafer5571]I own a 2001 Dodge Dakota. I am having the same problems. I have replaced the stat and the fan clutch with know changes. Please contact me at [email protected] if you figure out your problem.

Me 2. im glad 2 c im not the only one w this problem. i replaced the fan clutch, thermostat, radiator cap, hoses, even put a helper fan on the front of my tranny cooler. Im stumped and dont know what to do about it anymore.

maybe air in system or more realistic fan relay bad,is fan operating?

HELP. overheating the history is i have a new heater core, water pump, thermostat, today a hose blew off. fluid flows well through the system.

I think the radiator core is plugged up. Feel the top and bottom hoses and they should be hot indicating good circulation. Do the hoses have springs in them indicating they won't collapse.
A friends son had a Dakota and this was the problem.
