Hot weather can stop your vehicle just as dead as a burst of hot steel—it takes a bit longer, that’s all. Summer-wise GI’s will bear down early and often on vital items like these:
- COOLING SYSTEM—Drain antifreeze, flush system, install rust inhibitor. Check cylinder-head and filler-cap gaskets, thermostat, fan belt, pressure-relief valve, hose connections. Police up that radiator core. Look for leaks everywhere and always.
- AIR CLEANERS—Keep elements clean—with solvent. Maintain proper oil level (if any).
- FUEL FILTERS—Drain and clean element frequently.
- MANIFOLD HEAT-CONTROL—Switch valve to summer position.
- ENGINE—Wipe off heavy dirt and grease.
- VALVES—Adjust timing and clearances with extra care.
- BATTERIES—Watch electrolyte level. Water must be added more often in summer months.
- TIRES—Keep air pressure what it should be. Check tires when they’re coolest—and don’t bleed them when they’re hot.
