It is most likely that the pumps for standard and reverse recovery continue from each other. But to be sure, you should check with your dealer or manufacturer more often to get accurate information on your engine and water-coolant models. If you have an engine serial number, you can use it to find information about the water cooling pump for your engine. This usually leads to significant results on water cooling pump installation and replacement, including how to tell the difference between standard and reverse pumps. If you don't have the ability to get accurate information about his pump, you can install a sample and see if it works in the right way. However, this can be unexpected because an incorrectly installed pump can lead to engine failure. It is best to get help from professionals who determine the right pump for your engine.
