Do i need to remove both drain plugs for oil change?


Recommended Posts

I started on my oil change for my 05 CS, and i find that my upper 8mm hex bolt isnt coming loose but its starting to strip!!!!

I can loosen up the lower one no problem.

I was wondering if it would be an issue if i just drained from the lower drain hole and left the upper one?

Thanks

I drained the oil out of the bolt closer to the filter and when it was done draining I was able to drain about another quart from the second drain plug near the differential plug. So if you don't drain both, you would probably have at least a quart of old oil in there.

On a side note, I stripped one of the bolts that holds down the driver's seat when I was changing the battery under the seat. I had to use a bolt extractor to get it out but it worked after hitting it in place a couple times with a heavy mallet.

Something like this tool to get out the hex bolt. http://www.irwin.com/irwin/consumer/jhtml/...IrwinProd100509

Good luck.
