How to Remove the Exhaust Manifold on a 1993 Camry

The 1993 Toyota Camry base model came with the 2.2-Liter In-line four-cylinder 5S-FE engine. The exhaust manifold is attached to the cylinder head and routes toward the bottom of the engine, where it connects to the exhaust down pipe. There are no special tools required to remove the manifold; however, the six manifold mounting nuts, exhaust manifold gasket and exhaust pipe gasket all need to be replaced when installing the exhaust manifold to the engine and exhaust down pipe.

Instructions

Removal

1

Open the vehicle hood and support it with the hood prop rod. Lift the vehicle into the air with the floor jack. Place jack stands under the front frame rails of the vehicle. Lower the vehicle until it rests securely on the jack stands.

2

Lie down under the vehicle. Unplug the oxygen sensor wire harness from the oxygen sensor by squeezing on the plug and pulling it apart from the oxygen sensor pigtail without pulling on the wires.

3

Remove the nuts and bolts holding the exhaust manifold to the exhaust down pipe with the socket and ratchet. Remove the exhaust pipe gasket and dispose of it.

4

Remove the the six bolts that hold the upper heat shield to the exhaust manifold. Remove the heat shield. Remove the exhaust manifold mounting nuts with the socket and ratchet and ratchet extension. Remove both exhaust manifold stays with the socket and ratchet. Remove the bolts securing the lower heat shield to the exhaust manifold with the socket and ratchet. Pull the exhaust manifold from the engine and discard the engine-to-manifold gasket.

Installation

5

Remove any leftover gasket material from the cylinder head and exhaust manifold with the gasket remover and razor blade, if necessary. Set the new exhaust manifold gasket over the manifold mounting studs on the cylinder head.

6

Set the exhaust manifold onto the mounting studs on the cylinder head. Hand tighten the new mounting nuts to help hold the manifold in place. Install the lower heat shield mounting bolts and tighten with the socket and ratchet.

7

Set both manifold stays into place and hand tighten the nut a bolt. Tighten the nut and bolt for each stay to 31 foot-pounds of torque with a torque wrench.

8

Lie under the vehicle. Set a new exhaust pipe gasket onto the exhaust pipe and attach the exhaust pipe to the exhaust manifold. Tighten the mounting nuts to 46 foot-pounds of torque with a torque wrench. Plug the oxygen sensor wiring harness into the oxygen sensor pigtail.

9

Tighten the exhaust manifold to cylinder head mounting nuts to 36 foot-pounds of torque with a torque wrench. Set the exhaust manifold upper heat shield into place and tighten the bolts with the a ratchet.

10

Shut the vehicle hood. Lift the vehicle off the jack stands with the floor jack. Remove the jack stands and lower the vehicle to the ground.
