mellonman Posted April 10, 2019 Share Posted April 10, 2019 Hi just a quick one I see the part number is 16100-49846 for my water pump on my car Jspec TT. but when searching I see a lot of 16100-49847 for sale , so before I buy I wanted to make sure what the difference is or if there is any between that part number and what is the actual correct number is thanks Quote Link to comment Share on other sites More sharing options...
Rob W Posted April 10, 2019 Share Posted April 10, 2019 16100-49847 is the part number I used. I remember the propeller was different, pretty sure my old one was metal and the new was plastic. Quote Link to comment Share on other sites More sharing options...
mellonman Posted April 10, 2019 Author Share Posted April 10, 2019 arh that might be what the deal is with the code maybe they swapped to prevent corrosion , it was a old thread that I got that number from Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted April 10, 2019 Share Posted April 10, 2019 Yes, one is metal and one is plastic. The plastic one distorts with heat. Quote Link to comment Share on other sites More sharing options...
Rob W Posted April 10, 2019 Share Posted April 10, 2019 16100-49847 is the revised 16100-49846 discontinued part number. I’m sure you could still get them from stock tho. Pretty poor if Toyota made the newer 16100-49847 version of the water pump less in quality. Quote Link to comment Share on other sites More sharing options...
mattdavies Posted April 11, 2019 Share Posted April 11, 2019 You can google Aisin WBT-038 and that will get you a new pump front with out the rear part Quote Link to comment Share on other sites More sharing options...
