Don't start the water pump of Dongfeng sprinkler. What happened? The throttle doesn't move.

Two judgment methods: release the power take-off, close the vehicle, and turn the transmission shaft by hand. If it can rotate, it means the idle speed is low. If not, please enter the second method.

Second, the water pump is loose, indicating that the power take-off is crushed or the gasket is rotten. Please replace it. If it can turn, it means that the secondary impeller of the water pump is crushed to death. Please remove and inspect the vehicle.

Note: Generally speaking, the bearing unit of water pump is not easy to be damaged, but the power take-off is different.

Still can't solve it, you can contact me.
