I have a 1994 ford f-150 5.0 with a serpintine drive belt. the engine is out of a ltd car. he said it was getting hot. i found out that the water pump is spinng the wrong direction. how do i change it to run the other way? If i run the belt the way the 1994 ford f-150 5.0 diagram shows it spins the water pump backwards?
If in fact it is pumping the coolant backwards then it should also be getting hot
maybe not overheating but good and hot for sure
the only senseable soultion is to switch the drive belt to turn the pulley in the oppsite direction...@ least this way you`ll know if it was pumping backwards or not....
Question?
how did you come to find the pump running backwards???
to switch the pumps flow direction.....
most likely, you`ll need a longer drive belt to do this...
because
you dont want to switch the direction of any other part
like the alternator or smog pump....so probably you`ll have to go most of the way around the water pump pulley to accomplish altering its direction .
I`ve seen this exact problem before,but on a mustang 5.0ltr with the aftermarket performance pulley upgrade.....
even the pulley route sticker (provided by the pulley upgrade company) was incorrect....
so be careful and make sure you test..... only when the vehicle is cold
I recommend removing the thermostat prior to altering the serp.belt route...this way you can see the difference instantly...you may also find that a stuck thermostat could cause the appearance of the coolant flowing the wrong direction....boil the thermostat in a pot on the stove until the water is @ a good rolling boil....this is a grerat test for the thermostat you can clearly see a full open thermostat(GOOD) or no change in the thermostat indicating (BAD) replace defective and recheck coolant flow direction
i hope all this helps
if you need anything else
just ask
Good Luck
& be careful
