Hello, Planning to change the water pump to avoid head gasket issues How do I know which one I can pick to be safe? AISIN WPT 190 is 150+ while AISIN WPT 190-A is 250$+
I've just replaced the impeller in the two that I had that are now blown up and gone but the pumps are still here laying on the ground not sure what the a is about I don't know if I really care. It's a MAG drive type pump so unless something burns up in the housing usually all that's happened is the skin is peeling off the impeller you get a new impeller strip that one whatever and then it'll spin again or a new one will spin in its place the housing usually doesn't get messed up it's the impeller so replace of it what you'd like I guess we're just trying to keep the water moving that's all not too much heavy science about it.
I’d go for Aisin WPT 190, it’s the established choice. Might be cheaper for you here: https://www.amayama.com/en/part/aisin/wpt190 ^ I’m seeing $134 USD, on my doorstep, west coast Canada.
No, but it’s the option I’ll likely go with, once we’re “close” to 100k miles. Currently at 104k kms, may never get there.
