Review on Sierra International 23 3303 Impeller Kit by Roger Herch

As a loyal automotive customer i was very disappointed with this replacement part. As a result of my tests, I determined that it did not improve my engine cooling system. The kit seemed to be made of cheap materials which did not hold up to the stress of my vehicle's high temperatures. The only positive aspect was the easy installation, but it's not worth the price for the lack of performance .Overall, I would not recommend this kit for anyone looking to improve their engine cooling system..
