Engine Sender Unit Replacement

Drain engine cooling system to a level below unit.
2.

an exhaust port on L-6 engines and in the inlet mani-

fold near water pump housing on V-8 engines).

tion of unit.

DIRECTIONAL SIGNAL

Directional signal assemblies provide as standard pro-

duction equipment a lane changing feature and hazard

warning system on all model applications. Two different

design switches are used as shown in Figure 55. Major

difference between the two units is that one type has can-

celling and detent springs which are serviceable, other-

wise both units are not repairable and must be replaced

as an assembly in service.

Due to the integral design relationship of the signal

switch and the energy absorbing steering column, refer-

ence should be made to Steering, Section 9 of this manual
whenever any service operations are performed on the

steering column. The directional signal switch replace-

ment procedures covered in this section are intended to

supplement the detail service operations outlined in Sec-

tion 9.

Special note should be taken of the fact that different

signal flasher units are used in Chevrolet models depend-

ent on the number of lamps to be operated. The hazard

warning unit, even though an integral component of the

directional switch assembly, requires the installation of

an additional flasher unit in the fuse panel capable of op-

FUSES AND CIRCUIT BREAKER

A circuit breaker in the light control switch protects

the headlamp circuit, thus eliminating one fuse. A

separate circuit breaker protects the power window,

seat and top circuits. On Corvettes the headlamp motor
circuit is also protected by a separate circuit breaker.

Where current load is too heavy, the circuit breaker

rapidly opens and closes, protecting the circuit until

the cause is found and eliminated.

louses located in the Fuse Panel under the instrument panel are:

Wiper (Chevrolet, Chevelle, and "F" Car) 3AF/AGC 20 Amp.
