K5L cooling fans

[Doubeleive]

So the K5L 700w motors are the same motors used on the 6.2l with 9 blade fans?

There is not a 9/9 setup, something to do with harmonics or something like that. I could also be mistaken about which side the fans go on and confused that with relay activation and wiring.

you are probably right because I think if anything was going to have a 9/9 it would be the hummer and it only showed 7/9

I was just going by the part numbers James listed above.

K5L 700w motors are same part numbers as 6.2l 9 blade motors

From the shop manual:

The electric cooling fan assembly uses a 5-blade fan and a 7-blade fan. It does not matter which side the fan blades are installed on. DO NOT install two 5-blade assemblies or two 7-blade assemblies, as this would cause a noise issue.

Thanks for all the info guys, I'll take a look tomorrow and count the blades. If I need to I'll pick up the one that doubeilve listed and the new motors for cheap insurance

Apparently I already have the HD cooling fans, thanks again for the clarification
