Good Afternoon People!

I have an 87 2.8 (stock) that I want to change the oil pressure switch on. Exactly where is
the little bugger? I know it's around the water pump somewhere,but, it's kinda hard to make out
much in the spaghetti of wires and hoses.....

Thanks in advance.

If you have AC, it is the metal canister next to the battery, between the thermostat housing and the firewall. If you don't have AC, it is next to the oil filter.

If it has AC it is on the AC bracket to the right of the waterpump about 10". If it does not have factory AC, it would be just above the oil filter, angled toward the rear upper firewall.........Paul

I have a/c.
Thanks again. There seems to be a big price difference too. I get ~$28 from Autozone and ~$7.60 from
an online parts house for an A/C Delco part. What gives?

Here is a pic if this helps.
