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?

Thats easy to check with a chemical tester you can rent those for free from auto zone you just have to buy the fluid for it.

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.
