560 0 Posted July 8, 2006 when oil temp gets to around 85c the first oil pressure buzzer is sounding. it stops when it switches to the higher rpm switch. The car has 10w40 semi synth oil and a recent oilchange which helped cooling. Was worried about the high temps. thought at first the oil was thinning at these higher temps causing reduced pressure. The cooling system seems to do it's job but as my water temp guage isn't working i cant be sure of what temps its getting to. the rad fan works fine and no water is being lost. Has any one had a similar problem. i've heard the oil pressure switches are a known problem??many thanks. Quote Share this post Link to post Share on other sites
