Jacking points on a C4.
Somebody is always asking about where to raise a C4 with a floor jack.I was changing the oil and thought Id get a few pictures.I use the pinch weld in the frame,front and rear.The only problem with the rear is you need to watch for the E brake cables.I made these aluminum jack pads and then put some polyethylene plastic on that that.[IMG]

That's nice but it is overkill. After crawling under the car to place the floor jack in various locations, I finally just used the indicated places on the side. No problems. In fact, the front location can be used to lift both tires off the ground on that side. That makes switching wheels and tires easier.

Does that lift the entire front end? And where are you putting the jack stands when you lift the front?
As I plan on pulling the knock sensor and oil cooler hoses on my 89 so I can do a coolant flush.
I didn't want to lift one side, then put a jack stand, then lift the other side, then put another jack stand.
I bought one of those low profile GM jacks with the light. I say it would be good to at least use a piece of wood inbetween the car and the jack pad? It so, how thick should it be and what type of wood?

Where do you put the jack stands at? And do you put anything on top of the jack puck and jack stands like a piece of wood? I'm assuming from the above post that is used to keep from causing marks into the car.

I put the jack stands on the pinch-welded section near the towing hooks. My floor jack has a rubber pad on it, but my stands don't. I would imagine it wouldn't be hard to glue some kind of thin rubber cushion to the stands. The only time I've used wood with a jack was when I jacked up the engine slightly to remove the balancer pulley - I used a 2x6 between the jack and the oil pan. Otherwise I don't think I'd recommend using something that isn't physically attached to the jack.

Most will see this as overkill but the way I see it,why leave a mark on something if it wasnt there before.This is how I work on my car,at least my ZR-1.When I place a jack stand under the car I do the same with some aluminum blocks.Ive seen pictures of that 89,very nice.
