2006 Kia Sedona 3.8L VQ engine, I need to get in and replace the timing chain tensioner. Haynes manual says I need to remove the lower oil pan. When I lookup oil pan removal, it says I need to disconnect exhaust at the manifold (not enough space to pull oil pan out?). Several steps later it says I need to support the engine from below by placing jack with wood block and support the engine using the oil pan. Not sure what these guys have been smoking, but you cannot support the engine from oil pan when it is removed from previous step. Are they talking about upper oil pan? This is made out of aluminium. It does not sound wise thing to do. Is removing oil pan even necessary for this job? I am not planning on taking the timing chain out, I just need to replace the tensioner.

It usually isn’t necessary. There’s usually a handful of bolts that go up through the oil pan into the timing cover on cars where the timing cover meets the oil pan. They usually aren’t the easiest to get to, but removing the pan probably isn’t necessary. You might save some effort for yourself by jacking the engine up to remove said fasteners.
Getting your hands on the factory service manual may be well worth the effort/expense.

After extensive research I finally figured this one out. The lower oil pan is not in the way of removing the timing chain cover, it is simply not strong enough to hold the weight of the engine. Supporting engine by the oil pan is something I do without even thinking about on Japanese imports… but not these Korean cars.
My assumption was incorrect. The upper oil pan, which is made with aluminium is strong enough to support the weight of the engine. Looks like Kia technicians found this out through trial & error. The very first TSB they released, they tell you to just take the engine out of the car for this job.
Yes, factory service manual maybe worth the expense for doing complicated job like this, but I simply don’t have the money. I also don’t believe in getting illegal copies. What I am going to do is hit local library to access Alldata manual for this car. I am pretty sure it would be more detailed than Haynes manual.
thank you
