Where is the oil sending unit on a 1995 Buick Skylark 3.1 V6?

I can't find where the oil sending unit is. I know it's near the oil filter but I can't pinpoint it.

SOURCE: 1995 Buick skylark overheating

there could be several resons for the overheating:


1. water pump doesn't circulate properly

2. Bad thermostst

3. fan clutch/radiator fan are non operative

4. relay is bad

5. clogged system

6. clogged radiator

to check on the the specific problem first power wash the radiator to remove bugs and road grime. they block the air from flowing over the fins and coil of the radiator thus not allowing the heat to disapate from the coolant. next install the good thermostat and make sure the spring part of the thermostat is facing down.next fill the radiator with coolant all the way up to the neck of the radiator and leave the cap off. next turn your heat setting to max fan and max heat temp. start the vehicle let the vehicle heat up and keep watch for the the flow of coolant soon as it goes down you should feel the upper radiator hose get real hot this indicates that the thermostat is working. now if you have a fan clutch for a conventional rear drive vehicle once the temp reaches 180 degrees the fan should no longer free spin it should start spinning faster if it is working like it should. if you have a transverse mounted engine for front wheel drive you will have a fan unit mounted to the radiator. these should be spinning when the engine reaches temp of 180 degrees. If they are not open the junction box and located the fan relay. switch out the relay with another one( I use the a/c clutch relay)if the fans kick on it's the relay that is bad, if it doesn't then either it's the fan unit itself or the temp sensor on the fan unit.now after you have done all these checks and everything is in order check the hoses going to the heater core at the fire wall they should be hot to the touch if they are not you have a clog at the by-pass of the water pump or manifold inlet.if the hoses are hot and you still have no heat then it's a bad valve inside the cab near the heatercore or a defective climate control module. check the fuse first to see that it is good.after the engine has been running a while the level of coolant should have gone down and then refill to proper level and replace cap after all of this if you still don't have heat and it overheats you have a bad water pump.... please rate this thanks

The error that I'm showing for error code P1133 is 
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank).  I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done.  Hope this helps.  Thanks for an honest rating and for using FixYa.

No oil pressure


Does the engine make a bad noise, like it is not getting oil? If not, I would try replacing the oil pressure switch. I have had to do this twice in the past three years that we have owned my wife's 02 Buick.

Will a 1995 Buick Skylark leak oil if the Oil Sending Unit is burnt or bad?


Yes the sending unit will leak oil if it's bad. It will leak where the electrical plug clicks into the unit. If you disconnect the plug and remove the unit, you can see on the plug end where the oil leaks thru.

96 buick skylark runs about 3 seconds then dies.whats wrong?


Fuel pumps don't slowly go out, they either work or they don't. I recommend replacing the mass air flow sensor, which is the square metal piece that's mounted in the middle of the big air tube that runs from the air filter housing to the intake. I replace the front head on mine and during the reassembly, I forgot to plug the wire back into the MAF sensor and had a similar problem. I would have it tested first if possible. If u have any other questions abt this car, feel free to send em to me directly, especially if yours has the 3.1 V6.

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.

I have a oil leak on my 1990 buick skylark 2.5 motor coming from the back side of the motor i replaced the oil pan gasket the sending unit what could it be and how can i find it


I've had the same problem on other GM V6 motors. You need to have the rear main seal replaced to fix the leak. GM was notorius for oil leaks in those motors since the mid-80's and never did anything to fix the problem.
