Holden Z22SE Engine Parts

The Holden Z22SE is a 2.2 litre DOHC 16 valve inline four from the Ecotec family, naturally aspirated on multipoint fuel injection and built from 2000 to 2005. Holden fitted it to the Astra TS, Vectra ZC and Zafira TT; it is listed here for the Frontera too. The Z22SE uses a timing chain, not a belt, with a second chain for the balance shafts.There are 18 parts listed for the Z22SE.

Z22SE timing chain kits and balance shaft guides

A FAI timing chain set with gears, an NVP screw type camshaft chain tensioner, a timing cover seal and three NVP balance shaft chain guides. The guides come as two different part numbers, not a matched pair, so compare the worn guide against both listings before ordering.

Z22SE bearings and rings

TDC main bearing sets, ACL conrod bearing sets and NPR ring sets in 0.5mm oversize. The mains are also listed for the LE5 and LE9, the 2.4 litre Ecotec from the same family.

Z22SE head bolts, gaskets and water pump

NVP head bolt sets, a Victor Reinz lower gasket set, a Permaseal exhaust manifold gasket and an NVP water pump. The manifold gasket also suits the Z22YH, the direct injection 2.2 from the later Vectra.

Also listed for the Z22SE

Two camshaft and valvetrain parts and one piston set complete the page. The head bolts are stretch bolts, so buy a set with the gasket rather than reusing them.
