Anyone have to change the coolant union under the intake on a Z22 motor? Its a 1982 720 king cab.

Truck sat for 6 years behind my house. Drove it to work to drain the gas and found that fitting spitting coolant out.

The union is a 3 way connector that is a 27mm wrench. Is it easier to pull the intake or remove it still attatched to the intake?

I dont own a 27mm swivel socket, so going underneath appears impossible and my 27mm wrench only leaves a half inch to turn either way against the fender well which means it would take forever to turn out and tighten back in.

The intake is simple to remove... Just go that route

It doesnt look hard to take off at all but the bolt heads dont look in the best of shape. :frown:

Have a lot of cosmetic stuff and these minor problems keep popping off. :mad: Dont need to shear off an intake bolt. lol.
