I am converting my 7's old R12 to R134a. When I put my new (rebuilt nippon) compressor on, I had to use my original manifolds. Does anyone know what to torque these guys to? The paper I got with the compressor doesn't say. My Haynes manual (worst in the world) doesn't even acknowledge that I have A/C.

I am thinking maybe 12 to 14 ft lbs but am not sure. I have the factory model, not the dealer installed. The dealers sits very low in the compartment and has 2 fan belts. Mine is right up on top adn has only one fan belt. Also, the dealers doesn't use manifolds. The lines screw right in.

I would appreciate info.

 

tight enough it doesn't fall off, lol. goodluck on finding an answer other then that. peejay is the only person that might know that. otherwise compare the bolt sizes to a similar bolt in the haynes manual and compare from that.
