What is code E-32 on a Nissan forklift 5,000 lb. LP gas truck? Code comes up on the dash after the forklift is running for a while, then the thing does not run good at all. Do you have a fault code list with a descriptions or at least point me in the right direction of what could be wrong. Thanks.

Hello and welcome to fixaforklift

E-32 is an overheat code. See Error Code Chart
Before you start replacing any parts or what not, its best to follow the following steps.

• Blow out the whole truck especially the radiator because it is easily clogged and can throw that code.[

• When the truck is sitting and its cold check the radiator antifreeze as well as the coolant in the overflow tank.

• Coolant is 50/50 green. After you blow that out and refill fluid, then perform the foot stomp method or disconnect the battery for 15 minutes to reset the computer.

• If computer is reset and code comes back, it is possible that your thermostat is not opening or the radiator cap is not holding pressure.

• The radiator cap should test at 16 PSI if anything is less than that replace ASAP.

One way to test the thermostat is to use a Laser temperature gun. Let truck idle until it reaches operating temperature then check the upper and lower radiator hoses for temperature. The upper hose should be hotter then the lower since the radiator has taken the heat out of the coolant and it is going back to the engine through the lower hose. If they are at around the same temperature it is possible that the thermostat is stuck closed.

What is the "foot stomp methed"?
