Knowledge of fountain pump belts

Old models of fountain pumps generally use ordinary V-belt, and the new model of the fountain pump may use a serpentine belt. If the old model of the fountain pump installed in the new models, there may be some problems. Because the serpentine belt may drive the fountain submersible pump impeller in the opposite direction with the V-belt, thus causing the fountain pump to rotate in the reverse direction, resulting in overheating of the coolant.

Now more and more engines use the timing wheel of the camshaft to drive the fountain pump. The advantage of this is that the fountain pump does not rotate, and the car can not be driven and the engine length can be shortened. It must be emphasized that after a suitable period of time, the timing belt should be replaced. Sometimes see such a situation. The fountain pump is damaged in a very short time after installing a new timing belt, which is generally due to increased belt tension. Therefore, when installing a new pump, do not rush to switch to a new belt.
