ZR-1 1991

As title states , Does anyone know ?
1 How do you install the oil cooler ?
Seems like there is no way in the world to tighten the bolt at rear !
2 Do you have to remove driver side cat ? If so how do you get at front bolt ?
3 How tight does the plug that goes in the frost plug have to be ?
Thanks In Advance

If your talking about item #2, it gets torqued to 44 ft lbs.



Also, If you dont already have them. The installation iunstructions are posted here http://www.edelbrock.com/automotive_...rgers/1573.pdf

For those reading this, the Z06 kit is supplied with an oil cooler similar to that used on the new Camaro -

1 - Remove the manifold and cat
2 - install cooler
3 - Re-install Manifold & Cat

The "frost plug" you are referring to - is that the metric threaded plug with copper washer? If so, the torque is not high (under 25 ft lbs)

Hope this helps and merry christmas

thank you for posting , I have the instructions , no where is this in the instructions, Here is what it says.

95. Install the supplied threaded fitting into the hole

previously occupied by the freeze plug.

The other 2 bolts hold the cooler to the motor

101. Secure the oil cooler by tightening the bolts that
come with it into the flange on the oil pan, then install the
supplied bolt through the oil cooler assembly and thread it

into the bracket mounted to the oil pan rail.

No torque listed.

Thank You for reply , and MERRY CHRISTMAS to you too,
It's the plug. No 2 in picture . I have a Canadian Z06 , It came with a block heater , in that hole , instead of a frost plug .
I don't want to over tighten it , nor do I want it to leak either

I'll check the exact spec when I get to the shop and post back the correct spec
