Question about 2000 Mazda MPV
It appears that you have a viscous fan hub. Fan is mounted to a hub on the end of the water pump IT will have a big aluminium centre to which the fan is bolted. The hub is designed to start to lock up when the radiator gets hot and they were introduced to save fuel. However they will fail and when they do you will get an over heat situation at the lights. IT is best to replace them with a new item After market will be about 1/3 price of a genuine item and will be made by the same manufacturer. I have added extra silicone fluid to my Mazda fans but it is a time consuming job. However there may be shops that can do the job in your area. So yes it is a sign of a problem fan as when the engine is hot you would have difficulty holding it but not when it is cold.
