Best Fan Clutch Replacement?

Best Fan Clutch Replacement?
I need to replace my fan clutch on my 2000 Blazer. My Blazer occasionally has some overheating issues but nothing too bad. The water pump is going to be replaced soon, but I want to replace the fan clutch also.
I would like to replace it with an AC Delco 15-40684 and was wondering if anyone else has had any experience with other brands.
A local shop sells a Hayden fan clutch for about 1/3 the cost of the AC Delco one which makes me wonder why there is such a large price difference.

I replaced one on a friends blazer, bought it at advance auto,, there is a way to test that fan clutch to make sure its working or not.. unless you wanna just repalce it while your in there, go right ahead.. Also just so ya know they don`t come off like the older clutches did with 4 nuts and washers.. you`ll need a large adjustable wrench and some elbow grease, and you`ll be able to get it off the water pump.. when i changed the one i did, i left the belt on till i got it loose enough...

heres where i buy most of my stock replacement parts - Amazon.com
everytime i need a part i check out the part number on the amazons website with auto parts webssite and i usually find it for cheaper on amazon. yeah i dont get get a warranty this way but........... when i bought a delphi fuel pump for $150 instead of $300 at auto parts stores and it solves all my fuel pressure issues ........ then im very very happy........

Why are you changing the water pump and fan clutch? You say you have an occasional overheating issue. Can we get more info? I hate to see you go through the trouble of swapping parts and the truck still overheats!

I will be changing the water pump because my Blazer is about to turn 90K and I would rather replace the water pump on my own time than have it fail when I do not have the time to replace it.

By occasional overheating I mean that when my Blazer idles during the summer the temperature begins to rise after ~2 mins rather quickly. So I figure I am going to replace the fan clutch and see if that helps the idle heat problem.

What I found out here was that mixing regular antifreeze with Dexcool creates globs of gunk in the block and radiator. Learning about it 2 years later didn't help but it's something I wont repeat. After replacing my radiator I continued to have overheating problems until by chance I had to replace my lower intake manifold gasket and found the rear water ports were almost plugged with cork like crap. Standard garden hose type flushing never gets that stuff out so a complicated chemical flush is required. The like below is mind blowing for something that seems so simple.

Simple if it is not broke don't fix it if your water pump is not leaking don't replace it water pumps are not a mileage replacement part.(I have 190000 on my jimmy and never replaced the water pump but I did have your problem open the hood cold engine spin your fan if it spins more than one time while cold replace the clutch fan a good air hammer and the right adapter makes this job very easy

using an air hammer on a shaft with bearing and seals is a really good way to screw up the water pump. I would use a strap wrench and a large crecent wrench.
