Many of you have recommended that the water pump on the V6 be replaced w/one w/a metal impeller.
I'm wondering about this. There might be a reason that a plastic impeller was used...I'm not so sure that it had to be to save $$$$...sometimes plastic is more expensive. We've been discussing this at Advance (3 of us have Contours), & some of us feel that perhaps a plastic impeller was used because it is actually stronger & more efficient, & switching to a metal one could cause problems(?), since this cooling system was designed using a plastic WP impeller.
I understand that the problem w/these WP's on the V6 is not just the impeller cracking, but hitting the housing. If a metal impeller hits the housing & shears, I would think that would be even more of a problem than a plastic one doing so.
So, I'm thinking that it may be best to stick w/a plastic impeller WP, but just replace it every 40K miles since they don't seem to hold up?
What da ya think??
