ASRDogman .......do I remember correctly ......that you are running an aftermarket waterpump rotor/impeller?.......if so, would you mind telling for how many miles? ......Thank You
100,000 mi. WOW! ......thank you soo much.......I have this gut feeling, that a high % of head gasket failures are the result of a compromised water pump, due to a dragging impeller/rotor (not yet locked/up) ........I would be interested in your take on that theory......thanks again
I believe it is a combination of things. And it seems those that drive mostly highway miles go a lot further than those who drive mostly city driving. 301,000 miles for me. I was getting parts together and was going to set a date to replace it before it failed, but it beat me to it. It was a simple knock after sitting 20 minutes after a 20 minute drive. Then about the same thing a few days later. The coolant had only gone down very slightly. I had changed the impeller long before that though. And I only changed it because when I removed the pump the impeller was fine. But I dropped the pump as I was putting it back in place and broke it.
Fair enough! .....I'm going to change the impeller in my wife's 2010......130,000 mi. .....just because......Thanks again!
If it is the original one, and it is not cracked and spins freely, you don't need to replace it. But it's up to you
397,562 miles and I still have the original Traction battery on my Gen 3 2010 Prius 5 trim. I replaced the engine with a JDM 45,000 mile engine in March of 2021 at 268,000 miles on the original engine due to hydro-locked blown engine. New engine is doing fine with zero oil consumption at 129,000 I added plus the original 45,000 for a total of 174,000 miles total on the replacement engine.
