Allow the exhaust system to cool completely. The temperature must be less than 35°C or equal to ambient. Prepare fixture «31.2.220» and remove the lower gearbox cover and stiffener plate. Disconnect the loops of the oxygen content sensors in the exhaust gas and unscrew the sensors (5, 6, 9 and 13, see fig. 3.29) oxygen content in the exhaust gas from the exhaust system.
Support the exhaust system with a tool «31.2.220» (pic. 3.172), by installing it under the front muffler.
Moisten all exhaust system bolts with rust remover. The product can be applied by spray or brush. Wait a while for the rust to dissolve.
Remove all nuts (4, see fig. 3.30) mounting rubber pads (19) and remove the cushions from the brackets.
Fix the color of the pillows. The rear muffler rubber pads on the axle beam are red. Remove bolt (6).
Loosen the nuts (4) and disconnect the exhaust system from the exhaust manifold. Remove complete exhaust system.
Before installing the exhaust system, replace the gaskets and all self-locking nuts, having previously lubricated the bolt threads with a high-temperature copper-containing paste of type «Liqui Moly LM-50B-ASC» or «CRC». When installing the exhaust system on the vehicle, first tighten the nuts by hand on the entire system.
When installing the bracket (17), fix it on the pin and align the exhaust system so that the gap between the body and the system is at least 25 mm at any point of its installation. Tighten self-locking nuts to 30 Nm (3.0 kgf·m). Start the engine and check the tightness of the exhaust system by closing it with a cloth gag.
