Renault/Dacia Sandero cars are equipped with an exhaust system made of a single welded element.
And individual parts of the exhaust system are supplied as spare parts.
To replace individual elements, you need to cut the pipes connecting the elements according to special marks.
After that, the pipes are connected with a clamp, which is also sold in spare parts stores.
To replace the exhaust pipe and catalyst, we measure the distance between the marks (it should be 80 mm)
The marks are located between the catalytic converter and vibration damper, under the gear lever.
Mark the middle of the distance between the marks
And make an additional mark with a felt-tip pen
We place a screen made of refractory and heat-resistant material between the pipe and the bottom of the car (you can use a thin sheet of metal)
Saw the pipe according to the applied additional mark
Unscrew the two nuts securing the intake pipe
Remove the springs
Clean the intake manifold flange from the remnants of the old gasket
Remove the pipe bracket from the pillow and remove the exhaust pipe assembly with the catalytic converter
Do not knock on the body of the converter.
The active mass of the neutralizer core is very fragile under mechanical stress
Install the parts in reverse order.
We install a new gasket between the intake manifold and the exhaust pipe.
We connect the elements of the exhaust system with special clamps.
The additional and main muffler are replaced in the same way.
To replace the main muffler, you need to cut the pipe between the marks located near the left rear suspension spring
To replace the additional muffler, you need to cut the pipe in two places:
- between the catalytic converter and the vibration damper (under the gearshift lever);
- near the left spring of the rear suspension.
If necessary, you can remove the vibration damper from the old section of the exhaust system
To do this, you need to unscrew the two mounting bolts, and install on a new section.
