HT4100 engine
I live in Bulgaria and just bought a Cadillac Eldorado 1983 with HT4100 engine. A very rare car for ths region. The engine of my car is dismantled and the head gaskets repaced. Unfortunately my technican do not know the exact torch that is reccomended for the bolts on the head. At least you may know where I can find such data in the web.
Urgent help needed. |

Re: HT4100 engine
I already bought a manual but it's not shipped yet.
Torque spec is needed urgently. So is the sequence of tensioning. |
