1978 Toyota Corona Service and Repair Manual

Model-year accuracy matters most on a carbureted car, and this factory service and repair manual is tied to the 1978 Toyota Corona alone, so the clearances, adjustment settings and torque figures it gives are the ones Toyota published for the 1978 car and its sedan, wagon and Custom variants rather than values carried over from the years on either side.

Known issues on the 1978 Corona. One recall is on federal record for this model year, filed against the engine and exhaust system emission control and gas recirculation components. Under extreme temperature conditions, the fuel system pressure relief valve causes the valve spring seat to dislodge, and the fuel supply to the carburetor then decreases. Toyota has issued 3 technical service bulletins.

Whether you are chasing a fuel delivery fault at the carburetor, working through the emission control plumbing or setting a routine service interval on the automatic or standard-transmission car, it keeps you on Toyota's own procedure and the correct 1978 Corona figure.
