2003 Mazda Tribute, V6, 110,000 miles. ( Mazda Tribute is the same as Ford Escape And Mercury Mariner)

Overheating Happened on 23 Dec 2012
Checked:
Coolant - reservoir full but cold
Oil - levels are good
Cooling Hoses - no leaks but still cold as if coolant is not flowing through the engine
* Blows cool air through interior vents when turning on the heater during overheating
* Can drive it for 10 minutes before it starts to overheat

Please help...thank you in advance

It probably has air pockets in the system but it doesn't sound like you have even found the initial leak yet. You need to pressure test the system to finds the leaks and repair them.

Thanks for the suggestion but I have no leaks. I have been told maybe the thermostat is stuck on closed or my water pump may have gave out.

No, you don't know that at all. The system needs to be pressure tested before doing anything else.

If you don't find any leaks through pressure testing, you could have a water pump failure. If it is the original, it isn't uncommon for the plastic impeller to separate from the shaft. If the thermostat was stuck closed and you had no air in the system, your heater would still be blowing hot.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Well, overheating that fast after start does suggest a flow a problem...

I would remove or hollow out the T stat and see if that makes a difference.....No matter what you find you are going to what to change out the stat since you've overheated the system...If it still overheats then you are going to want to look at the pump..

If you can locate the inlet heater hose, you can remove that a run the engine to see if you are getting flow...If you have a bad impellar then there will be little to no flow....If the pump is good then make sure you have a good extention hose on the heater hose and a good way to contain the coolant or you will have a big mess to deal with.....

Nobody has pressure tested this system yet. It is full of air and that coolant went somewhere. Even a totally closed thermostat is not going to make the heater cold.

I may have misread this but it looks like the OP had the overheating problem, then checked the system and it was full....

Thanks everyone for the help, I will be taking this to the shop today and I will update you on what they say. Do you guys recommend system diagnostics to be performed? Last thing @ Sidom, you are correct that the coolant is not going anywhere as levels never changes, the reservoir and the radiator hose is cool to the touch when the car is overheated. Thanks again.

I was thinking that this system had a separate radiator cap but I see it has a pressurized bottle. I've seen a few of these DOHC engines with the impellers rotted off the water pump.

Just back from the shop, they are 100% sure that the waterpump went out and needs replacement because no coolant was flowing and the vents was blowing cool air when turning on th heater.

Went to Rockauto.com and bought new waterpump, waterpump belt and thermostat for safe measure. Labor is going to cost me $220 install everything...sounds about right? Thanks again...

My 03 Tribute is also overheating, I've changed the thermostat, water pump, water pump pulley and belt, radiator as well, My coolant is not flowing from the overflow bottle the top radiator hose gets rock hard and hot after 15mins of idling and the bottom radiator hose remains soft and cool to touch. If I remove the cap off the overflow bottle the pressure releases and the top radiator hose gets soft.
