There is also a V- belt and serpentine style that both use the 4-bolt mounting of the fan clutch - that setup would be easier to swap back and forth. The different style pulleys change the distance from the engine the belt runs, so changing from one to the other is not easily possible.

All the bolt holes are the same on the blocks of 1st & second gen engines - only difference is 1st gen is SAE threads, 2nd gen is metric. Everything will bolt right up from one to the other - you just need the hardware .. and on a second gen you;d have to remove a stud or 2.

Again, just FYI for those who want to know. Buying the correct pump for your year-model is the easiest way to ensure a bolt-on-and-go setup with no modification.

Different brands, different numbers, the pulling or pushing type - on man.

I just uploaded some photos of my pump to: Blazer - Blazer

Hope it will be clear enough to see what exactly I have. I don't have that hexa bolt like some have.

Sure would like to finish this ordeal.....

At this time it doesn't matter if they ship to Europe or not - I just need the exact pump.

TIA
