E) Coolant Level: Have the coolant level checked during each stop at the gasoline station. Add water to bring level to about 11,4' below the bottom of the filler neck. Overfilling will dilute the anti·freeze and also result in coolant loss through the overflow tube. CAUTION: Driving In heavy traffic, at high altitudes, or in very hot weather may build up pressure in the cooling system. When removing the cap place a cloth over the cap, turn left to first stop, allowing steam to escape through overflow tube, then remove cap.
Thermostat Your new car is equipped with 180 degree thermostat for use with perma· nenl-type anti-freeze. If you later prefer an lcohol type anti-freeze use only a 160 degree thormoslat.
Manifold Heal Control Valve_ A cold engine will warm up faster and accelerate more moothly if the valve that controls heat flow In the manifold works freely. It is normal for I d deposits to accumulate in time on the y lve shaft causing it to tighten up'. Manifold II t Control Valve Solvent, available from your dealer, should be applied a t six month lnt Iva Is. Slide shaft in and out and rotate a
, w times to distribute the solvent. Apply only when manifold is cool.
The Carburetor A ir Filter. The special easy to change fire-resistant filter installed in your carburetor should be cleaned and inspected every 6 months and replaced once every two years, to assure good fuel economy. Clean or replace more often when car is driven in dusty or sandy areas. Replace filter if damaged. DO NOT wash or oil. Simply remove the metal container, unscrew the wing nut and lift out filter. Clean with compressed air, holding nozzle about two inches from filter.
Fuel Filter. Your new car has a filter in the fuel tank to prevent water and foreign material from entering the fuel system. There is also a fuel filter in the fuel line at the fuel pump outlet. If this filter is plugged it can limit car speed and cause hard starling. Under normal operating conditions the filter should be changed at 20,000 mile intervals, or every two years.
011 Cap Filler. The cap on the oil filler tube is a combination ventilator and permanent filter. The filter inside the cap should be kept clean to allow clean air to remove combustion product s from the crankcase. To clean the filter wash the entire cap periodically in k ero sene and relubricate with SAE 30 engine oil.
ENGINE PERFORMANCE EVALUATION
Engine operation efficiency depends on correct ignition, carburetor adjustments, and on valve lash where applicable. To obtain best engine performance, Chrysler Corporation recommends that the engine be evaluated every 10,000 miles and tuned, if necessary. Services performed during this evaluation should include the following:
SPARK PLUGS-Remove and inspect each spark plug. Most plugs can be cleaned, adjusted, and reinstalled. Rough idle, hard starling, frequent engine miss at high speeds, or apparent physical deterioration, are indications that the spark plugs should be replaced.
DISTRIBUTOR-Clean and inspect the dis· tributor cap and rotor if required (wash cap in household detergent and water solution). Check breaker points for abnormal pitting. distributor secondary wires and tower caps are clean and connected properly. See that ignition timing is set to vehicle specifications.
CARBURETOR-Remove and clean air filter. Check operation of manifold heat control valve and choke diaphragms, use solvent recommended. Clean crankcase ventilator system. Check and adjust choke fast-idle cam and fuel mixture.
BATTERY-Check specific gravity. Clean and tighten terminals; apply grease to post and terminals. Check circuit voltages.
