Rarely have had to replace a water pump on any of my vehiles. My 1990
5.7L Suburban needed a new one at 109,000 miles and my 1985 2.5L Celebrity got over 102,000 miles on its water pump. The 1987 2.8 Liter Blazer needed a new pump at 120,000 miles and now has 90,000 miles on that pump. The trick is to maintain the cooling system as well as you maintain the engine oil or transmission (do it on a regular basis).****************************************** I would rather be exposed to the inconveninces attending too much liberty than to those attending too small a degree of it. ~ Thomas Jefferson ~
