Oldsmobile Calais

changing the crankshaft sensor

They were almost naked, in their underclothes, and wearing nooses around their necks and holding the keys to the city and castle.

olds cutlass calias bolt removal. you must remove the air box, the radiator cooling fan and anything else that is in your way from accessing the alternator from the top, front of the car. a longer extension on a 3/8 drive ratchet and the proper size socket,13mm or 15mm should remove this bolt.

it has something to do with the passcode security feature on the car. To fix it you leave the key in the run position for about 10 minutes unitl the securtiy light shuts off and then start the car normally. This could be one of 2 things either the key is worn or the passcode module is shot. Get a new key before you go and spend $300 on the parts. There are more answers on www.automotive forums.com If it does not start turn the key all the way to off position then turn it to the on position, at this point the security light will start flashing for between 10-15 min. Once it stops flashing or goes away turn the key all the way off then try to start it. If passcode locks you out , security light will be on. I don't think that the engine will even turn over. It could also be fuel pump. When you turn key to on position , fuel pump in gas tank should run a couple seconds (hear a hum).

If you run your cars gas tank to almost empty alot, the electric fuel pumps fail because the fuel acts as a coolent. Also check the fuse block. The fuse block on my son's car was removed and it was found to be very corroded. The engine would turn over, but not start. The ODB II reader could not read any codes. The problem was worse when it rained. There must have been a leak that caused water to corrode the fuse block.

its the kick down solenoid on the transmisson try replacing egr valve or pcv valve

The price would depend on wheather it is a valve cover seal, oil pan seal, or a head gasket.

stick a siphon hose down the filler neck and start sucking.just don't sollow any, and then wash your mouth out. they stopped making the calais in 1991.....tuner1978

Remove the inside door panel and see what has happened. Only then will you know the problem.

if the car is a 95 and up, it under the exhaust crossover pipe

I have an 87 Calais automatic with a floor shifter. The console doesn't have to come out. The bezel around the radio snaps into the lower dash with 4 clips. Carefully pry out the bezel and then you'll be able to get to the mounts for the radio. I have pictures of the dash with the radio removed if it will help.

Rear end of the engine - front end of the transmission

This MAY be caused by the fact the cam shaft was binding from no oil and put added stress on the timing belt causing it to break. The camshaft will be first to starve from a LOW OIL or NO OIL state. Hope this was helpful.

I have a 91 calais. Oil filter is located in the oil pan. Just remove the large diameter plug, located next to the drain plug, and pull filter out with a pliers

My 87 had the same problem. I could hear the fuel pump but still no fuel pressure. I replaced the fuel pump and found the small black hose from the pump to the sending unit was rotted, desolved maybe from fuel additives? maybe from time. Then I blew out the fuel lines with low pressure air and found a wad of yuk in the line! I had the fuel filter off and the stuff splatted on my rear passenger tire. Worked fine after that.

It's on the passanger's side of the 3.8 engine, the biggest pully (crankshaft pully) on the towards the bottom, behind the tire.

You'll have to take off the tire to get to the crankshaft pully, and you'll need a 15/16 and possibly a "pully puller", I'm working on the same problem right now and the pully puller sucks so I'm trying to find another way to get the crankshaft pully off.

========================================

My edit:

On a 3.1 it is in the rear of the motor. (see how to change spark plugs on 92 olds cutlass supreme) to lean how to rotate engine forward to gain access.

My local GM dealer to me it was at the crankshaft pully, an hour later, it was not there! Went to the library and looked it up in a Chilton... yes it is in the rear of the motor! And yes, they (the old CKP sensor) often test good, within spec but are actually bad! I know from experience!

look in google images you should be able to find a diagram for you

on the back of the tach. is a special clip to change it from 6cyl. to 8 cyl. and i believe it is something to do with that. Dave

I took a look at doing this myself and backed out. The shop had to remove a engine mount and dismantle the A/C to get the job done. I think shop time was 3-4 hours. This car does not leave enough room for big hands. Also to give you a heads up on another issue I had. Leaves and debris enter by the wipers, clog up the A/C drain. The car starts getting wet on the inside passenger floor board. I though I had a leaking heater core. Replaced it. Eventually the water takes out the computer behind the glove box. HTH
