: High Engine Temp Low Oil Pressure

04-10-11, 09:33 PM
When at idle or going slowly (revs under 2 grand) in my 2001 Catera the oil pressure would suddenly drop and the Engine temp would rise. As soon as I build up revs they return to normal. What can be causing this? How much is it to fix? I'm hoping its just the themostat not sending enough coolent at low revs but with a Catera its never the easy fix so I figured I'd ask.
