This engine sits sideways so do you mean "behind" as in the front is where the serpentine belt is and the back is where the trans-axle is? Or "behind" as in the dashboard side (back of engine compartment) and "front" the radiator side. Or did you mean I need to remove the starter/manifold to get to them? This engine is totally new to me, but I do like to do my own work so any help is great. The Haynes Manual doesn't mention them.

I would really recommend going over to EBAY and getting a factory service manual for your car. They are a little higher than Haynes but there is no comparison. They generally come in a set of two or three.
