So how long do they last?.I bought my 94 S10 in 1997,I think the dealer threw in a new battery,not sure,but it's still got the same Delco battery in it,nearly 8 years.
I just replaced the water pump,the seal failed ,140,000 it lasted.Did the gas sender too,10 years of rough NY winters did it in.Other than that,only the alternator need a bearing and the usual brake job every 50,000 miles.
I been driving used Chevy trucks since the mid 70's most were rusted high mileage bombers ,but none of them gave me any problems other than the rusty brake lines and a radiator or two.
My only non Chevy was a beater 74 Dodge van with a Slant Sludge engine.It had so much blowby,water vapor would freeze in the oil pan,darn engine wouldn't pick up oil pressure on a cold start.I would start it,run for a minute, shut it off,wait a few minutes,do it again until the little bit of engine heat thawed the ice in the pan.Other than typical Mopar starter and alternator problems,it always got me to where I wanted to go.
