How do you prime the oil pump?

Answer 1

Well that's a rather vague question and it depends on where the oil pump is, and what type of pump it is.

If it's a automotive mechanical oil pump in a rebuilt or new engine that has never been started, then you can do as follows. I'm going to assume that you've put oil in already. You might want to check to make sure you have adequate oil prior to proceeding.

1. remove the spark plugs.
2. using the starter turn the engine over for 20-30 seconds.
3. wait a minute (to allow the starter to cool)
4.repeat steps 2 and 3, 3-5 times.
5. put the spark plugs back in.
6. Check the oil level and add as required (the oil filter when filled can hold about a quart of oil. Circulating the oil as you have been doing will cause the filter to hold some oil.)
7.start the car. Follow the manufacturers procedure for the break in period for your engine.
