An oil pump is a mechanical system that strikes oil from the oil pan to the engine’s shifting elements. A correctly functioning oil pump is important for engine lubrication and cooling.
There are a number of methods to check an oil pump. One widespread technique is to make use of an oil strain gauge. An oil strain gauge measures the strain of the oil within the engine’s oil galleries. If the oil strain is just too low, it might point out an issue with the oil pump.
