Wish I could help but ...............
$490 for a water pump ????!!!!The only water pumps worth that kind of money are industrial grade that can pass a house cat if they have to - not some pump the size of my son's fist. When I retire, a small machine shop could make these things and give me an income probably exceeding any salary I've EVER made.One COULD rig a water pump from the car market (small 4 cyl water pump) for a pulley, some brackets etc. and replace the #$%^& thing twice a year for 5 years and NEVER hit $500.00 !!!!!!!!!!!!Just a thoughtReminds me of the piece of rubber to seal my sail drive for which Volvo wants almost $500. No Thanks, I'll make something before I go that route !!!
