Question 1

What steps should be followed to safely replace an exhaust manifold in the 3.0L V6 engine on Mitsubishi Montero?

Accepted Answer

Before beginning the procedure, the engine must be totally cool. First, disconnect the battery's negative cable, and then raise the vehicle and support it properly on jackstands. Use penetrating oil on the exhaust manifold fasteners and allow it to soak before disconnecting the oxygen sensor elctrical connector. Take off the bolts and nuts holding the front exhaust pipes to the manifolds and lower the pipes. By unbolting the left manifold, detach the EGA tube followed by unbolting the nuts near the cylinder head to remove the heat shield(s). Thereafter, unscrew the nuts that hold the manifold to the cylinder head and lift the exhaust manifold off. Examine via inspection the manifold and fastening devices for damage. Using a scraper, you must remove all previous gasket material and carbon build-up from the surfaces of the manifold and cylinder head. If a gasket leak is indicated, have the manifold checked for warpage and resurfaced as needed. To position the new gaskets, place the marked gasket (1-3-5) on the right cylinder head and a second marked (2-4-6) gasket on the left cylinder head over the cylinder head studs. Fit the manifold and screw on the mounting nuts, tighten the nuts from the centre outwards in three or four equal steps to the specified torque. Reattach all the remaining components in a reverse order while replacing the exhaust pipe gaskets. Finally, start up the engine and look for any leaks.

Question 2

How to remove and install the exhaust manifold in the 2.0L and 2.4L four-cylinder engine on Mitsubishi Montero?

Accepted Answer

Before detaching the exhaust manifold, first, disconnect the battery's negative cable. Engage the parking brake, block the rear wheels, lift the vehicle high enough to work on it, and support it with jackstands. Detach the exhaust system from the exhaust manifold by removing the nuts underneath, using penetrating oil on their screws to loosen them. For carbureted engines, remove the air cleaner assembly. Disconnect the oxygen sensor wire. If a secondary air system is fitted, apply penetrating oil and unscrew the flare nut on the air injection tube, before removing it from the manifold. After, unscrew the three bolts holding the heat shield to the exhaust manifold and lift the heat shield off. Use penetrating oil on the threads and take off the nuts, brackets and emission components holding the exhaust manifold. Now, slide the manifold off the studs and pull it out of the engine compartment. In preparation, clean and examine all threaded fasteners and repair. Ensure any gasket material is removed from the jointing surface and check for damage cracks. A new gasket is placed on the studs, and the manifold is fitted with the nuts tightened in stages, starting at the centre and going outwards to torque. In reverse of the removal process reinstall other parts and run engine to check exhaust leak.
