walkerstrider Posted June 3, 2015 Share Posted June 3, 2015 Does any body know how many water pump variations were fitted to the na? I ask because I've bought a new gasket from Toyota going off my chassis number. This however doesn't match up to the water pump housing on a separate na lump ive bought to do a turbo build. The water pump housing on the spare lump seems to match the tt water pump! Going off pics online. Cheers for any input. Quote Link to comment Share on other sites More sharing options...

Scooter Posted June 3, 2015 Share Posted June 3, 2015 I have an NA and TT registered on TOYODIY and the 46041 is the NA gasket, 46030 the TT one just so you can check against what you have. Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted June 3, 2015 Author Share Posted June 3, 2015 Cheers mate, I'm guessing regardless which water pump it is, it'll still work? Quote Link to comment Share on other sites More sharing options...

It ends 46041, so it's definitely an na gasket. Someone must have replaced the water pump for a tt one in the past. I'm just gonna replace like for like.

Chris Wilson Posted June 4, 2015 Share Posted June 4, 2015 The NA and TT pumps are similar, but the mounting bolt pattern differs, one will NOT fit the other. Quote Link to comment Share on other sites More sharing options...
