I have a 1989 F150 with a straight 6 4.9L engine. I had the a/c serviced and was told if I did a lot of city driving I needed to replace the missing fan shroud to improve cooling. I ordered one off Ebay, it came with no instructions. Do I remove the fan clutch and blades and then slide it all back in together? Thanks for your help. Also, this truck is a short bed 4x4 5 speed with 130K miles. I only get 13 miles per gallon. Is this about normal for my truck? Thanks for your help.
I know on my truck it was not possible to pull the shroud without pulling the fan. Just separate the fan/clutch assembly from the engine AT the engine pulley, pull the fan out, position the fan inside the shroud and drop both of them in together. The shroud should drop into 2 clips at the bottom of the radiator and will bolt to the truck in two places at the top. Good luck.
What is the easiest way to remove fan & fan clutch?
Thanks for all the help. Could you tell me the quickest way to remove the fan & fan clutch? I tried taking off the serp belt and removing 4 bolts from pully the fan clustch is attached to and only the pully itself loosened up. Am I supposed to leave those 4 bolts in place, wedge a screwdriver across two of them and try to loosen the large nut on the clutch shaft itself? Any help appreciated. Bill
The pulley should be sandwiched between the water pump and the fan mounting thingy. You should only take out those 4 bolts and the entire fan and clutch should come off. It may take a couple of taps of a hammer to knock it loose.
You have an 89 .... I don't know if they still used the bolt on clutch .... but on my 90 4.9L it has the screw on clutch .... it requires a special tool ... and sometimes a 25CFM 150PSI compressor and an air chisel to break it loose. If this is the one you have, I would suggest removing the radiator to slide the shroud around the fan and clutch assy .... then reinstall radiator and clip/bolt shroud in place as the easier route to take, who knows, you may need a coolant change anyway.
