Wish I had an aircooled but since I don't I would like to get as much information about my "new" watercooled baby. Talking with a long-time 1.9L VW van owner the following opinions were expressed. Would appreciate the List's feedback. 1. The fan sensor switch is too low in the radiator to do a good job preventing overheating during low speed travel [therefore install a manual override switch]? 2. The water pump does not flow enough coolant during idling in stop and go driving [this guy installed a smaller pulley onto the waterpump shaft - is this recommended?]. 3. Radiator cooling capacity is insufficient during high ambient temps while endeavoring to climb 7% or greater grades [therefore install a larger radiator]? 4. Highway speeds of greater than 65 MPH will result in headgasket failure caused by overheating? 5. The factory temperature guage is not a reliable indicator of dangerously high coolant temperature - anything past half way actually indicates an over temp condition that should be addressed by pulling over and shutting down the engine immediately?
