Question 1

How to remove and reinstall an oil pan on V6 engine on 2002 through 2006 Toyota Avalon?

Accepted Answer

Start by removing the hood, disconnecting the battery, and elevating the vehicle. Remove engine splash shields, drain oil, and remove oil filter. Disconnect front exhaust pipe from catalytic converter and remove flywheel housing cover. Detach the oil pan by removing bolts securing it to the transaxle and block. Remove oil pump strainer/pickup and oil pan baffle plate if present. Clean mating surfaces and apply RTV sealant to the aluminum pan section. Inspect and clean oil pump pick-up/strainer assembly, install it with a new gasket. Apply sealant to the steel oil pan section and position it on the aluminum section. Reverse the steps, let sealant set before adding new oil and filter. Run engine and check for oil pressure and leaks.

Question 2

How to remove and install an oil pan on Four cylinder engine on 2007 through 2015 Toyota Avalon?

Accepted Answer

Disconnect the cable from the negative battery terminal. Set the parking brake and block the rear wheels. Raise the front of the vehicle and support it securely on jackstands. Remove the two plastic splash shields under the engine, if equipped. Drain the engine oil and remove the oil filter. Remove the oil dipstick. Remove the bolts and detach the oil pan. If it's stuck, pry it loose very carefully with a small screwdriver or putty knife. Don't damage the mating surfaces of the pan and block them, or oil leaks could develop. Use a scraper to remove all traces of old sealant from the block and oil pan. Clean the mating surfaces with brake system cleaner. Make sure the threaded bolt holes in the block are clean. Check the oil pan flange for distortion, particularly around the bolt holes. Remove any nicks or burrs as necessary. Inspect the oil pump pick-up tube thoroughly for cracks and a blocked strainer. If the pickup was removed, clean it thoroughly and install it now, using a new gasket. Tighten the nuts and bolts to the torque. Apply a 3/16-inch-wide bead of RTV sealant to the mating surface of the oil pan. Carefully position the oil pan on the engine block and install the oil pan-to-engine block bolts loosely. Working from the center out, tighten the oil pan-to-engine block bolts to the torque in three or four steps. The remainder of installation is the reverse of removal. Be sure to wait at least one hour before adding oil to allow the sealant to properly cure. Run the engine and check for oil pressure and leaks.

Accepted Answer

Remove the hood. Disconnect the negative cable from the battery. Raise the vehicle and support it securely on jackstands. Remove the engine splash shields. Drain the engine oil and remove the oil filter. Disconnect the front exhaust pipe from the catalytic converter, the two bolts and the support bracket, and the nuts holding the pipe to the front and rear exhaust manifolds. Remove the flywheel housing cover. Remove the two bolts holding the aluminum oil pan section to the transaxle and air conditioner compressor bracket. Remove the 10 bolts and two nuts securing the steel oil pan section, and detach the steel pan. If it's stuck, pry it loose very carefully with a small screwdriver or putty knife. Remove the oil pump strainer/pickup. Remove the bolts securing the aluminum oil pan section to the block. Remove the oil pan baffle plate if necessary. Use a scraper to remove all traces of old sealant from the block and oil pan. Clean the mating surfaces with lacquer thinner or acetone. Make sure the threaded bolt holes in the block are clean. Check the flange of the steel pan section for distortion, particularly around the bolt holes. If necessary, place the pan on a wood block and use a hammer to flatten and restore the gasket surface. If the baffle had been removed, reinstall it now. Clean the mating surfaces of the engine block and aluminum pan section, being careful not to gouge the soft metal, which could lead to leaks. Apply a 4 mm wide bead of RTV sealant to the aluminum pan section. Install the aluminum pan section within five minutes and uniformly tighten the bolts. Work from the center out towards the ends of the pan. Inspect the oil pump pick-up/strainer assembly for cracks and a blocked strainer. If the pick-up was removed, clean it with solvent or thinner and install it now, using a new gasket. Tighten the fasteners. Apply a 3 to 4 mm wide bead of RTV sealant to the flange of the steel oil pan section. Carefully position the steel pan on the aluminum section and install the bolts. Working from the center out, tighten them. The remainder of the installation is the reverse of removal. Be sure to add oil and install a new oil filter. Run the engine and check for oil pressure and leaks.

If the pick-up was removed, clean it thoroughly and install it now, using a new gasket. Tighten the nuts/bolts. Apply a 3/16-inch wide bead of RTV sealant to the mating surface of the oil pan, following the groove but going to the inside where the bolt holes are located. Carefully position the oil pan on the engine block and install the oil pan-to-engine block bolts loosely. Working from the center out, tighten the oil pan-to-engine block bolts. The remainder of the installation is the reverse of removal. Be sure to follow the sealant manufacturer's recommendations for assembly and sealant curing times. Run the engine and check for oil pressure and leaks.

Question 5

How to remove the Oil Pan on V6 engine on 2007 through 2015 Toyota Avalon?

Accepted Answer

The manufacturer recommends removing the engine and transaxle assembly to perform this procedure. To begin, drain the engine oil. Next, remove the bolts and nuts securing Oil Pan No. 2 to the larger cast aluminum oil pan. If it is stuck, tap it loose with a rubber-tipped mallet or carefully cut the sealant with a putty knife and hammer. Remove the oil pump pickup tube/strainer assembly and then the bolts and nuts securing oil pan No. 1 to the engine block. Carefully pry the oil pan loose from the engine block, being cautious to only pry in the designated areas. Remove the O-rings from the bottom of the engine block and, if necessary, the sheet metal baffle plate. For installation, first install the baffle plate if it was removed. Clean the mating surfaces of the block and oil pan and ensure the threaded holes in the block are clean. Install new O-rings on the block and check the flange of the steel oil pan for distortion. Flatten and restore the gasket surface if needed. Inspect and clean the strainer before installing it with a new gasket. Apply RTV sealant to the upper oil pan flange and position the pan onto the block, tightening the fasteners in several steps. Apply RTV sealant to the flange of the No. 2 oil pan, position it on the upper oil pan, and install the bolts. The remainder of the installation is the reverse of removal. Add oil, install a new filter, run the engine, and check for leaks.

Question 6

How do you remove the oil pan on Four cylinder engine on 1997 through 2001 Toyota Avalon?

Accepted Answer

Remove the engine splash shields, drain the oil, and remove the oil filter when servicing the oil pan. Detach the exhaust pipe from the manifold. For installation, get rid of the old gasket material from the oil pan. Apply specific RTV sealant to the oil pan flange, put the oil pan on the engine, and tighten the new bolts to the proper torque.
