Expert: Rocky Racoon Date: 6/3/2007 Subject: 2000 New Beetle Cooling Problem
Question Hello,
I replaced the thermostat on the 2000 New Beetle 2.0 SOHC engine and read where the water pump impellers were possibly plastic. While having the thermostat "gooseneck" off, I was able to actually see the impellers of the water pump and they rotated as they should while bumping the engine. If the impeller is rotating I presume it should be pumping. This leads me to believe I may have blocked lines or a severely corroded radiator. Any suggestions? The coolant was filled with rust and I am now planning on a flush. Also, have there been reports of bad electric motors on the fans for the radiator?
Answer Bud..Hi there, did you do the thermostat replacement yourself? When you refilled the engine cooling system, did you follow the factory guidelines on evacuating the entire cooling system to a pressure of 2 bar, and then refill with fresh, low phosphate, pink coolant from your Volkswagen dealer? Since the gooseneck was off it should have been possible to feel the impeller with 2 fingers. I always feel them to see if they are still secure on the drive shaft. Cooling system problems are created, more often than not, by not getting the system filled with the right stuff, and not starting with a fully evacuated system.
