No matter how much oil you have stored in your oil reservoir and no matter how good the quality of that oil, it won't do your vehicle engine any good if such oil is unable to reach the engine's various moving parts. In short, the oil will be useless if your car's oil pump is malfunctioning.
What is an oil pump?
The pump is the mechanism that creates pressure in order to drive oil into the nooks and crannies in the engine, lubricating metal engine parts as they work and carrying heat away from the combustion area. In such manner, the pump is able to protect the engine from damage caused by heat and friction.
What types of pump are available today?
If you are in the market in search of a new oil pump, you'll find that there are different types in use today. The most common are:
- Rotary pump. This pump is composed of two rotors: an inner and an outer rotor that mesh against each other. Oil flows through the pockets between the two rotors, in such a way that the oil is squeezed and then forced out into the engine under pressure.
- Gear pump. Similar to the rotary pump, this type of pump also works using two components, these time gears. They mesh against each other, and it is the action of their teeth coming together that draws oil and then drives it out under pressure.
Despite the differences in their technical composition, both types of pump achieve the same purpose. So how do you find the right pump for your ride? If you're looking at price and getting savings, you can choose from these:
- New oil pump. As the name implies, this comes brand new right out of the box. It might be costly (price ranges from a little below a hundred bucks to almost a couple of hundred), but you get complete warranty and brand new parts.
- Remanufactured oil pump. This kind of pump is usually created out of a used and damaged pump. The damaged component is removed and replaced, then the pump is rebuilt to like-new condition-ready for use again. It is generally cheaper than a new pump.
- Salvaged oil pump. This is a second-hand pump, used but still in good condition. You'll find this in a car junkyard, or from a friend who might be doing an upgrade and discarding his old but still usable pump.
With all these choices available, you're sure to find an oil pump that will match your need and your budget.
