Had a heater hose blow on me Wednesday, b4 that
happened my oil pressure switch worked good.
After cleaning off engine the oil pressure stays at
0. Do I need a new switch ?

1 Answer

On 5/2, Antifreeze was coming out from the back, come to find out my heater core connection popped. I cleaned off the engine with water. B4 this happened,my oil pressure switch/gauge worked good. Afterwards, my oil gauge on dash wont go any higher than 0. I just changed the oil today.5/3/2018, Still no change and now on the dash read out, it says low oil pressure. Is this a bad switch because I cleaned off the engine ?
