Fiero oil


On some 4 cyl models, the oil filter is in the bottom of the oil pan. It is a large round metal plate with a nut in the middle.
Removing the filter also drains the oil. It can be very messy.

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

Why does my low oil pressure light comes on when making left and right turns


Oil level is probably low. When you turn, your oil splashes to the right or left and your pump is not able to pick up the proper amount of oil to pump. If the level is proper, you might have the wrong grade of oil. Check your owners manual for proper weight for the driving sonditions you are in.

I have a 1987 pointiac Fiero. It has the 2.5L 4


if you've added the oil and started the car and the oil level is at the add mark with the engine off, allowing a minute or so for the oil to drain back down to the oil pan, add 1 more quart

Does fuelpump have to go to oil senser


Are you reffering to the conection ? If your oil sending unit senses your oil pressure is low, it will in turn open the circuit to your fuel pump relay.
Please let me know.

Hello, I have a 2007 GMC Yukon with around 47K miles.All service has been done at a GMC dealer on schedule and a oil change was done about 1500 miles ago. My question is that this week the oil low/check...


Probably just the oil sending unit internally defective.Just have them install a pressure tester and make sure the pressure is good.I`m sure this will be the sending unit.Hope this helps.Good luck.

HOW DO YOU TURN THE OIL LIGHT OFF


If the oil light is on, Don't drive your car until you've checked the oil level .
The oil light is an indicator that warns you when the oil level has dropped to an unsafe level and will not allow proper oil flow thru the motor because the oil pressure is dropping.

Don't take a chance! Check the oil level. Make sure it's between the full and add 1 quart line. If you don't see anything on the dipstick, it's really low... If you run your car with low oil, you're going to freeze up the motor.

If the oil level is ok and the oil light is still on, have the pressure sender checked to make sure there's proper oil pressure. The light will stay on if there's a problem..

88 fiero starts on it own, but wont stay running.


the brain is not sending the proper fuel pressure codes to the fuel rail to evenly distribute the fuel to the intake and fuel rail.
perform a fuel pressure test check on it ok? also run a diagnostic scan on it and see what codes come out.

Try replacing the Idle Air Control Valve. If that does not work (which it should) try fixing the Throttle Postion Sensor.

Low oil pressure in 1998 camaro ls1


First have your oil level checked and make sure that it is at the right level. If not that's your problem, if your level is good you may have a bad oil pressure switch. This can be checked by using a oil pressure guage. If switch is bad replace and solve the problem. However if your vehicle has alot of wear and tear on he engine and you were using 20w-50 oil and it was replaced with 5w-30 that oil may be too "light" for the vehicle and you would get a low oil pressure reading. Good Luck
