These fantastic engines, are very widely fitted to many car makers, as GM added to its stable of makes.  So over time, even the sump plug got changed a few times.

Is there an easy way to tell which sump plug is fitted to my car?
Fortunately, there is. Rather than looking at loads of tables with engine numbers etc, and then still getting the wrong one, because the table wasn’t 100% right, just follow the these simple steps:

 

Have a look underneath the car at the sump, locate the sump plug and see what it looks like.

 

  •  Does it have a round conical head (26.5mm dia.) with a 155mm Hex Head on it?   Then it is an SP15:

  • Does it have a round smooth outside (25mm dia.) with a 45 Torx head inside?  Then it is an SP6:

  • Does it have a round smooth outside (26mm dia.) with a 13mm Hex Head on it?  Then it is an SP14:
