You may have a defective thermostat. Also check all the radiator hoses. If one or more are pinched and/or collapsed internally that to could cause the circulation problem. The last option is to consider a blockage in the engine block or heads.

Water not circulating radiator engine running hot

Hi ytabaja97,
Sounds like the thermostat on the hose that goes to the top of the motor is stuck closed, or does not open completely. Try replacing the thermostat. Make sure it is correct for your Jeep, and that the seals on the thermostat housing are replaced correctly.
Hope you have no more overheating problems.

Heater only blows cold air. I have replaced the thermostate and blown clean the heater core. also replaced a control switch ($280). Sick of getting ripped off.

When the van is warmed completely check the top radiator hose by squeezing it together. If you can squeeze it without any resistance replace the radiator cap. The coolant is not circulating properly and can keep the heater from working. If you cannot squeeze the hose together than you may have a bad water pump. The water pump has fins inside of its' case. Those fins may be rusted completely off to where the water cannot circulate. You can check the circulation by feeling the top and bottom hose coming off of the water pump to the radiator. Both those hoses should be the same temp. If not I would consider changing the water pump.

I put on new water pump.Motor still gets red hot.could it be rad.

You need to make sure the coolant is circulating. Check to make sure the top and bottom hoses are hot and firm to the touch. If the bottom hose is not hot and firm the water isn't circulating which means the thermostat is stuck in the closed position. Also check to make sure the radiator isn't clogged or doesn't have to many crushed fins that prevents the air from properly cooling it.

2001 kia sportage is over heating but has no leaks. the radiator has been flushed but is very rusty inside. The water is rusty inside the radiator. We have checked the resevoir, it is fine. the water...

Rusty is from running a bad or no mix of coolant. (PH level is off) You may have a water pump that has corroded impellers, and can't move the coolant as well any more. I would start by making sure to flush the engine block again, and make sure you flush water through every possible hose, and where you can get at it.
