post icon 1999 Chevy Venture Oil Pan removal Sign In

1999 Chevy Venture
3.4 V6 extended van (doors on both sides)
199,000

I have removed all the bolts out of my oil pan and the pan will STILL not budge. its so tight just like the bolts are still in there. I have double and triple checked and I have them all removed that I can see. I have removed the starter to get those bolts and on the passenger side near the tire the plastic covers and have full access. I have got 2 different stories on how to remove the oil pan. One says I have to lift the engines after loosing the lower engine mount and more people saying no just need to remove the bolts and use a rubber mallet. please help if you know.

Don't forget to take the six bolts out that are on the sides of the oil pan.

They are in there. The bolts have their own gaskets and fasten the sides of the oil pan to the main caps. The ones on the transmission side are a pain.

I don't believe you will get that pan out without supporting the engine from above and lowering the sub-frame even after you get all the bolts out..

Re: 1999 Chevy Venture Oil Pan removal Sign In

HT is right. You need to support the engine using a support adapter, so you can get the mount bracket out and to hold the engine up with the pan off. You don't have to lift the engine, but you can lower the right side of the subframe down enough to get clearance to remove the engine mount bracket. Don't use a mallet.




Got confused because I thought you were at the point where you were unbolting the pan to remove it.

Yes, because the right engine mount is bolted to the oil pan. Without that mount there is nothing to hold the right side (front) of the engine up.

I was waiting for an answer like that but it's not accessible any way.

Re: 1999 Chevy Venture Oil Pan removal Sign In

I just did an 02 Venture awhile back. I'm not positive if they are exactly the same but I'm sure they're close. Like HT and DS mentioned, where are you going to put the blocks to support the engine? The only place to support the engine from underneath is the oil pan. You HAVE to support it from above because you have to remove the motor mount as it connects to the oil pan. I'm with HT in that I don't see you getting the pan off without dropping the frame. It's only held on by 4 bolts. Two in the front and two in the back. Once the frame is off you better make sure you have it supported good. They make a special engine support fixture. You might be able to borrow one from a local parts store. You just have to put down a deposit that is returned when the bracket is returned. I ended up making one. Don't try and rig anything unless you're absolutely sure the engine is supported because you'll be underneath the engine. I had to remove the ac compressor to get my pan off. I just took the bolts out and left the lines attached. Once the frame is off things are much easier to get to and you'll probably be able to get a better look at the 6 side bolts. Trust us, they're there. They're towards the top right below the gasket. They are probably covered with crud so clean up the outside of the pan real good. Just to reiterate. Don't try and take a shortcut on supporting the engine without the fixture. You'll be replacing a lot more than the oil pan gasket and that's after you're released from the hospital!

I don't think you have to remove the catalytic converter like it says although I can't say for sure without crawling under mine and looking. I don't see why you would need to.
