Pontiac Grand Prix Oil Pan

Oil Pan is also known as oil sump that is located in the Pontiac Grand Prix to store the engine oil, which is necessary to lubricate all the parts of an engine and cool them. The Oil Pan employs the wet sump system whereby, the oil is sucked through a pickup tube then pumped within the engine before falling to the pan. It is important that this design is in place so as to keep the engine in great performance throughout its use. Normally, the Pontiac Grand Prix has a stamped-steel oil pan, but with the current market changing there are cars with cast-aluminum oil pans. The general purpose of Oil Pan is not changed irrespective of the model, but there can be some changes in the manufacturing materials and the layout of the pan due to some change of the configuration of the engine or depending on the performance. On balance of things the Oil Pan is a very important part of the car and specifically the Pontiac Grand Prix cars.

Each OEM Pontiac Grand Prix Oil Pan we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: How do you remove and reinstall an oil pan in 2.5L four cylinder engine on Pontiac Grand Prix?
A: Before disposing the oil pan it is necessary to heat up the engine, to drain the oil, and to delete the oil filter. Pull the cable out of the negative terminal, while making sure that if the Theftlock feature is present in the audio system, it has been turned off. Then, drain out the coolant, unbolt the engine torque strut, unbolt the coolant reservoir, unscrew the air cleaner assembly, disconnect the air inlet tube and reach the drivebelt and remove it. Remove the dipstick tube, put the car on stands and place a floor jack on the front transaxle and wooden plank on the back of the engine. In the case of air-conditioned models, free the air-conditioner from brackets but do not unplug the hoses. Go on to take/undo the starter, lower bell housing cover, and the engine wiring harness retaining screws/removal of screws under the oil pan. There is no splash pan, but take off the bolts and nuts of front engine mount bracket, and transaxle mount nuts, then lift the engine and transaxle assembly up about 2 inches. Take off the front engine mount and bracket, free the frame bolts and the bolts and nuts holding the oil pan to the engine block. This gasket has a special seal that requires the pan to be tapped with a soft-face hammer before pulling it off-the other type of gasket can simply be pulled off without prying. After that clean the engine block and oil pan blunt by removing all the old sealant and make sure that the threaded bolt holes are free from it. For installation examine the sealing flanges for undue stress and use a punch to flatten if the case so requires. Scrub down the mating surfaces and then apply RTV sealant in a steady, unbroken line along the sealing flanges and front protective cover face, do not overdo the application of the sealant. It is necessary to put a thin layer of RTV sealant on the ends of the rear oil pan seal and then fit the oil pan on the block. When installing the bolts, begin from the center then progress in a circular fashion round the outermost edge to prevent applying lots of pressure. Last of all replace any component that may have been shifted for access, apply oil on any component that required it, fit the new filter, start the engine and inspect for any sign of leakage.
