A sealing gasket is installed between the flanges of the cylinder head and the manifold, made of two thin molded metal strips, interconnected by spot welding
If the gasket is leaking, the exhaust gases will burst outward, accompanied by a characteristic sharp sound.
If the malfunction cannot be eliminated by tightening the collector fastening, replace the gasket.
You will need: wrenches "for 10", "for 13", socket head "for 13", pliers, ruler, blade probe.
Disconnect the wire from the negative terminal of the battery.
Remove the decorative engine cover.
Disconnect the exhaust pipe of the additional silencer from the collector, to do this, unscrew the nuts securing the exhaust pipe flange to the collector flange, disconnect the suspension cushions from the silencer brackets and remove the exhaust pipe flange from the studs of the collector flange.
Remove the additional muffler.
Press out the clamps of the harness block
Disconnect the wiring harness connectors for the control and diagnostic oxygen concentration sensors from the engine harness.
Press out the tendrils of the holders
Disconnect the harness holders for the control and diagnostic oxygen sensors from the steering gear heat shield.
Unscrew the bolts securing the collector to the bracket with a “13” socket head.
Using a 10 wrench, unscrew the three nuts securing the heat shield of the steering gear to the engine shield (two nuts are located under the steering gear)
Remove the shield
Unscrew the two nuts securing the water pump inlet pipe bracket with a 13 wrench
Remove the bracket.
Unscrew the eight nuts securing the manifold to the cylinder head with a 13 wrench
Remove the collector
Remove the gasket.
Install the new gasket and all removed parts in the reverse order of removal.
Check the flatness of the collector flange surface.
To do this, place the ruler with an edge on the flange surface and measure the gap between the flange plane and the ruler with a feeler gauge.
Grind the flange surface or replace the collector if the gap exceeds 0.1 mm.
In order to prevent the gasket from sticking and to increase its tightness, we recommend lubricate the gasket on both sides with a thin layer of graphite grease.
Lubricate the exhaust manifold mounting studs with graphite grease.
