So did he replace the fan motor because there was power and ground to the motor and it was inop?Or was that just a wild guess?What gasket is he talking about replacing?Also why does he think the gasket is bad?Does the radiator fan motor work now?Does both upper and lower radiator hoses get really hot?

You rent the tester by the chemical run the car with the tester sitting in the radaitor where the cap goes with the chemical in the tester. If it turns a certain color you have exhaust gases in the cooling system.

I dont know what a dodo dooo noise is i cant hear it and dont know where on the car its coming from.Also a chemical test is the best way to verify that you have a bad head gasket cracked head etc.So if it were mine i would use the chemical test to see if there were exhaust gasses in the coolant.

Heres a couple guides on overheating, read them and it may help shed some light on what you are trying to describe

Engine Cooling problem
2005 Nissan Murano 6 cyl Front Wheel Drive Automatic 53K miles

I have a 2005 Nissan murano that started overheating when we were driving through Texas. We had it towed to the nearest Nissan dealer and they told us that it was the radiator cap. So, they changed it and the next day we started driving again and it did the same thing. Anyways we have gone to 3 Nissan dealership and a local mechanic and they seem to not be able to fix my car. Basically they've changed the thermostat changed unnecessarily things and the problem still persist. I drive about 65-80 miles with ac on at about 71 and up degrees and the car starts overheating. When I stop and turn the car off I can hear bubbles sound under the hood and all the coolant comes up. Please help........... We have spent about $1500 on this car and all these darn mechanic don't know whats wrong with the car well they say they fix the problem but, once we get the car back it does it again.

Hi there,

make sure that the A/C condenser fan is turning on, have the radiator cleaned & flow tested, make sure that there is no build up of debris between the radiator and the condenser blocking air flow, check foe any external coolant leaks, start here.

It is never a good idea to drive a vehicle that overheats. Maybe, if you know what is causing it to overheat, you can drive it a short distance. Maybe. But I would not even suggest that. I would suggest diagnosing the problem before you turn a simple problem (maybe a bad $10.00 thermostat) into a big problem, like a blown cylinder head gasket that could cost you over $500.00 to fix.

First thing's first; when the engine is cold, check the coolant level. If the coolant level is low, then borrow a cooling system pressure tester from your local AutoZone, Advance Auto, or O'Reilly Auto Parts store. Hook up said pressure tester and pump it up to see where the leak is.

Here is a how-to guide: https://www.2carpros.com/articles/radiator-pressure-test

Do not pump it to more than 23psi, as that could cause more problems. 14 psi should do it, really.

Let us know what you find.
