7AM - Tepic
This morning MsTioga and The Team are heading up the hill to the City of Tepic. We have some shopping to do. We especially need to refill MsTioga's propane tank.

There is some thinking about staying in Tepic for a few days because of the upcoming holiday. It sometimes gets pretty noisy near the beach when holidays arrive.

11AM - Engine overheating
As MsTioga was climbing the mountain to the City of Tepic, her engine temperature rose to very hot. MsTioga has been having an intermittent problem with overheating. Her cooling system does not leak. The radiator is filled with engine coolant.

We believe that the overheating problem is caused by a faulty thermostat. So, we have gone to the Ford dealer in Tepic to have the thermostat changed out.

6PM - Engine still overheating!
The installation of a new engine thermostat is complete. However, the engine is still overheating. While the mechanic was checking out his work, I looked at the fan clutch using the mechanic's light. It appeared that although the engine was overheating, that the fan clutch was running slow!

This fan clutch observation means that it is very likely that the engine thermostat was operating correctly and that the overheating problem is likely caused by a faulty fan clutch. MsTioga will be returning to the Ford dealer in the morning to have the fan clutch replaced.

I am wondering if while having the fan clutch replaced, that the water pump should be replaced at the same time since the water pump is directly behind the fan clutch. I will ask the Ford service manager his opinion about the water pump.

The cost to replace the engine thermostat is $51US.

PS: Don't you believe that MsTioga has an extraordinary amount of engine cooling failures? Hmmmm?
