This info is regarding 8v version - 12v may be different.

O2 sensor is threaded into the lower part of the exhaust manifold. Some newer cars might have an additional one near the cat. Be sure to saturate it w/penetrating oil(PB blaster,wd40,etc) before attacking it.

On my 8v 4G15, the temp sensor is threaded into the intake manifold near the t-stat cover.

Torque recomendations for O2 sensor is 33ft lbs and for the coolant sensor 19ft lbs.

Be advised that the O2 sensor can be extremely difficult to remove!
