toledo 0 Posted May 15, 2011 Picked up my water pump from TPS on saturday , taking it out of its box i see it has a plastic impeller. Is it a bit anal to be worried by this as i know there are aftermarket ones available with metal impellers ( i paid trade so cost was about same for the genuine one ) I'm also replacing the top radiator flange as it weeps but would you guys recommend doing the thermostat or / any other flanges at the same time as i don't want to replace the old G12++ too many times . I need to get this sorted so i can start procuring the bits for the 288mm front & mk4 rear brake upgrade. Cheers Quote Share this post Link to post Share on other sites
boost monkey 0 Posted May 15, 2011 Yours is a VR6 isn't it? If it helps a number of newer VAG engines have plastic impellers in the water pumps. Quote Share this post Link to post Share on other sites
toledo 0 Posted May 15, 2011 Yeah it's a Rado VR6 , i know lots of VW group vehicles are built with plaggy impellers but some guys seem to have a real distrust of them ? A search for a Leon Cupra on autotrader or pistonheads shows lots with the water pump changed for a metal impeller type. Quote Share this post Link to post Share on other sites
dannyboy 0 Posted May 16, 2011 some of the early 1.8t engines had the platic impeller water pumps which the impeller rounded off on the pump drive shaft.get a metal one for better insurance Quote Share this post Link to post Share on other sites
Supercharged 2 Posted May 16, 2011 Plastics fine, more likely to do damage with a metal one... Yeah change all the plastic bits like the stat housing and the crack pipe Quote Share this post Link to post Share on other sites
