low oil pressure switch
OK i'am stumped low oil pressure switch located right side of motor in back
of oil filter housing. I was able to remove the el connection,but how do i get that switch out. area tight as it looks like a thin wall socket might get it out. Not sure what size socket to use at this time. I'll pick up the new switch on Monday so i will be able to see what size socket to use. So far i have removed the oil cooler lines , oil filter , and center wheel housing. With that out of the way it looks like i could get a thin wall socket into the tight opening .

Re: low oil pressure switch
John,
I pulled out a housing I had laying around and looks like you can get a normal 3/4" socket on the sensor no problem. Rich Opps, sorry wrong sensor, disregard....

Re: low oil pressure switch
Hi Scrrem,
No problem found the answer by going to solutions by Dynomite. He shows a pic of oil filter housing with the oil pressure switch light on dash ( low oil pressure switch ) The best way was to go to FSM oil filter housing section and follow instructions to remove oil filter housing. Got the housing out and had to use a 1/2 drive socket to remove the defective pressure switch. I do not believe that i could have removed the switch with housing in the car ( hands to big ). The auto parts store has a new switch for me, i"ll pick it up Monday. Thanks, John Becker white/black 1990 #2546 one of a few auto (4L80E ) eq. ZR-1's |

Re: low oil pressure switch
Hi John,
Of course there is more than one way to do it. I like to remove the center wheel house panel. Then jack up the right side of the engine. The trick is to get a "sensor socket" when you acquire the sensor. The sensor has a special shape, for the tool, sort of a shallow 12 point shape. Best of luck. |

Re: low oil pressure switch
Well the job is done , but of course the lower samco hose (water pump )
stock hose clamp did not seat the first time. so took it apart 2nd time and got the stock house clamp to seat correctly , no more drips. While i had the oil filter housing out i installed a 3/4 in long pipe with a 90 deg. fitting. now the switch is out in the open and easy to get too. And of course it lasted for 120xxx miles before failing. so now i'll never? have to rpl it again. While i was in there i replaced the coolant with 50/50 mix of NAPA and distilled water plus one bottle of water wetter. Removing the left coolant hose and filling it until it ran out of the left cooler housing. Started the car i had coolant flowing into the tank and added more until it was full. I used a temp gun while running motor , checked both coolant housings and read temp of 175 deg temp. on both sides. Went for Test drive everything checked out ok. Thanks for your help John Becker 1990 white/black #2546 one of a few auto (4l80E ) eq. ZR-1's |
