Warm Weather Tips

As temperatures increase, so do the demands made on your vehicle. So make sure your vehicle is up to summer's challenge.

Check tire tread depth for excessive and uneven wear.

In extreme summer temperatures, you may have to change the grade of your engine oil. Check your owner's manual for the viscosity grade recommended for your vehicle's engine.

Check the cooling system – both hoses and radiator – for leaks. Check the coolant recovery reservoir under the hood when the engine is cold. Add the coolant if needed. Replace conventional coolant every two years or 60,000 miles (every five years/150,000 miles DEX-COOL®).*

Check the air conditioning system.

After a winter of coughing and sneezing, combined with allergens, bacteria, mold and other microscopic interlopers, you might need to replace your cabin air filter (if you have one) and thoroughly clean or vacuum interior surfaces.

Winter can take a bigger toll on your vehicle than you think. See your GM dealer for a springtime check-up.

* Maintenance needs vary with different uses and driving conditions. See your Owner’s Manual for more information.
