ok the oil pressure sender is just beside the oil filter needs a 17mm spanner and the oil temp sender is beside that think its a 12 or 14mm spanner. Not a bad job if your fairly handy on the tools, spanner will only have enough room to move 1/4 turn or less at a time. Also do the job when engine cold as some oil will come out of both holes. Check thread of both new sensors if the have like a sealant of some sort all good if not put a very small amount of plumbers tape of equivalent thread sealer on. Be careful not to block the hole or put too much on. Good luck!
