2003 E350 5.4 van engine fan is not working and maybe the 2 year old thermostat is done as well...
Water pump has not been removed. Fan clutch is attached to the water pump. O'Riley's rents a tool that is composed of multiple spanner wrenches made from 1/8" plate. I spent two hours trying to remove the fan clutch with the spanner wrenches and a 2# hammer wielded laterally and got nowhere.
youtube videos show some guy using a pipe wrench and a hammer to get the threads on the clutch to break free. I have a 14" adjustable wrench attached to the clutch "nut". Hitting the wrench handle with a 2# hammer does not free the threads. The belt is not tight enough to hold the water pump shaft from turning. Even when using the spanner to keep the water pump pully from turning, the threads will not break lose. No torch available.
Also...the bolt head on one of the bolts that holds the thermostat cap in place no longer has a 6 point head. Got the first bolt out but it was torqued over 40#. The crown on the second bolt has been stripped. Tried a bolt extractor but the extractor cannot grip what remains of the bolt head.
Anyone able to surmount either of these problems?
