    Cooling Fan Removal

    New guy here. I am installing an 04 5.3L from a Tahoe into a 55 Chevy suburban. Have a couple of questions.

    How the heck do you remove the fan from the water pump? I assume there is a special spanner wrench required, but are they left or right hand threads?

    Thinking about using the gas tank with fuel pump from a Tahoe, pickup or suburban for my transplant. Does anyone have any dimensions of these tanks?

    Thanks for any help.

    hey welcome to the site..to remove the clutch fan you can use an air chisel or if you dont have that you can do what i did, i installed all the accessories, the belt, then took a open ended wrench then slapped the mess outta it with a BFH and it loosened it right up.

    It is a normal right handed thread, just like every other fastener on the truck.

    What myzterray said. I used a big adjustable wrench. Have it setting straight up an down in the 12 o'clock position, then I used a rubber Mallot and gave her little smack, Like you're hitting the wrench toward the passenger side. Worked like a charm for me several times. I'm sure this is the redneck way, and that's fine by me cause I'm a redneck, but there's tool made specifically for this.

    I bought a $15 strap wrench from sears (make sure it's a large one, I grabbed the biggest one they had) to hold the pulley and then used a big crescent wrench. In my experience the belt doesn't always have enough tension to hold the pulley. The one in my 03 wasn't that tight, but in my 00' it took some swearing and beating to get it loose.

    the easiest way by far is with the air hammer though, if you have one, or access to one

    Agreed, that's how I take them loose.

    i used a big adjustable wrench and a pair of vice grips since my motor wasnt in the truck and didnt have a belt on it. i had to use the rubber mallet to break it loose but it wasnt hard to get off. it turns counter clockwise to remove as stated earlier.

    Actually, off subject but I can think of some lefthand threads on the truck, can anyone guess where?
