I bought a new water pump for my 89 S10 Blazer with the 4.3 V6. The guy at Autozone wanted to know if I wanted a standard one or the heavy duty. I bought the heavy duty one because it was only $5.00 more. Are they just built stronger or do they actually move more water?
Same thing, may have a cast impeller instead of aluminum. You wont benifit from it at all, and even if it did move more water it really wouldnt do you any good anyway, its not necessary
The intense flow in simple terms strikes greater water in line with revolution the a manufacturing facility pump. Heavy accountability must be the comparable because of the fact the hi-flow, whilst the electrical powered pump would not use the fan belt to coach the pump, this is have been given a small electric powered motor to try this. See if there is any distinction between hi-flow heavy accountability, get one in all those.
Mistake #1. Auto Zone doesn't stock anything close to the quality as an OEM part. If you want a better than average OEM water-pump get an aluminum Stewart Stage 1, 2, 3 or 4. The impeller builds more engine and cylinder head coolant pressure which prevets steam pockets in the heads. Little does Jason know that not all water-pumps created equal.
