Electric fans on my 2000 GMC Sierra 1500
Is it worth the upgrade and if so what's the best/easiest route to go to install some? Mine has a 4.8 but I'm planning to build and install a slightly cammed 5.3 in the future. TIA

Reliability? Ill tell ya whats not reliable is the darn fan clutch! I replaced at least 5 of them the first ten yrs I owned my truck. Swapped to "BeCool" fans and a good harness ran thru the computer and have not had an issue the last 3 yrs.. Not to mention you now have two fans and the chances of both going out are slim to non! Although the gas savings is minimal, there still a slight gain in mileage and no drain on the motor which has to be worth something.. I say go with the fans. The way it should have came from the factory to begin with!

I also did the efan swap. I just bought a 34" core radiator like from the newer trucks equipped with efans and then bought the e fans from ebay that go with the newer models. All in all i had about $400 tied up in it and it totally chenges the way your engine compartment looks, it cleans it up a lot. This isnt one of those modes where you will pick up 20 hp and 3 mpg but it is one one of those mods that adds to the overall package. Its a good supporting mod to do along with other things. I also used the blackbear efan harness

If you are lucky you might be able to find an 05-06 truck in the junkyard. I was able to get the fans and the factory fan relay for <$100 which is wayyyy cheaper and factory than those flexalite fans. Assuming that you have the 34" radiator (get it with the fans) and a blackbear tune (efan tune only is $55) in that might cost more.
