2 technical questions about Enclave- exhaust and rear suspension - MuddyZ chime in here if you can:

1. Does the Enclave (and other Lambdas) have a catalytic convertor? If it does, I haven't seen it. The exhaust appears to start off from the 2 manifolds (one for each side of the V), then goes through a special mesh pipe (seems to allow system to move with car movement), then to a large muffler (that doesn't appear to be a catalytic convertor, but very well could be), and then to a split Y to 2 smaller mufflers.

2. Rear suspension: Are they struts or shocks? I thought I remember reading somewhere the car had all struts (the front is definitly strut). The rear looks like shocks, not struts. This make a big difference to extended warranty coverage. GMPP only covers struts, not shocks.

Unfortunatly the person who originally answered this is no longer on this forum and has removed all of their posts.

The answers were:

1: The catalytic convertors are actually connected directly to the exhaust manifolds (there are 2) They are difficult to see but are right under the engine.

2: It is unclear if the rear suspension using struts or shocks. Waiting on release of service manual to find out

I did my first oil change (1800 miles) I like to change the oil in a new car earlier then prescribed. I will do the 2nd change over a longer period.
With the enclave up on ramps (does make the job a lot easier), it was quite easy to do the change. The hardest part was getting the filter off from the top. The engine factory (not LDT) seems to put the filters on too tight. In any event draining the oil was a breeze.

While under the engine I finally found the catalytic convertors. MuddyZ had told me there are two of them, one for each side of the V6 exhaust manifolds.

I am glad it went well. I hope I helped in some small way at least.
