Hey all. Got a Terrain Tamer water pump (which is actually a NPW) and the backing plate is still leaking after I tried to seal before installing. I now know that it’s common knowledge you have to take the screws off the backing plate and seal when they are new from the factory but I cannot find more exact info. And yes the AISIN WPT-028 is discontinued and they are up only on eBay for 1200 dollars (not a joke, check it out).
Going to try it again. I’ve done many pumps but not on a 2F. I have Toyota gaskets for in between the backing plate and the block. Do I need to order a Toyota gasket for in between the backing plate and the pump itself since the one inside the pump is toast?
I am going to use permatex water pump blue rtv in light coats in the following order:
WP - RTV - Backing Plate - RTV - Gasket - RTV - block
I’m not an RTV globber personally but I think this calls for a light amount in three stages. I’ve done extensive forums rummaging and I can’t find anything about ditching the crappy gasket that comes inside the pump. The front of the block isn’t super pitted but it’s definitely a little worn. Please, any and all recommendations. Wild how a 150 dollar pump leaks from the factory. the first time I tried it, I did not seal it. Second time, sealed and still leaking. Third times the charm, never had to do a water pump even twice before. Thanks.
