Timing chain replacement: Suzuki SX4 VVT 1.6 (M16A)

🧭 Before you start

Remove the cylinder head cover, hoses, spark plug leads and coils as needed, the oil lines and the chain guides, then screw in the tensioner plunger, fit the retainer and remove the tensioner.

Turn the crankshaft two rotations by hand and confirm the position, refit the timing chain cover on fresh sealant with new O-rings, then the oil lines, coolant pump pulley, sump and head cover with new gaskets, tightening in the given sequence. Lock the crankshaft pulley with the special tool to refit it.
