Start with tires and brakes
Check tire pressure when tires are cold, inspect tread and sidewall damage, confirm the spare/inflator situation, and listen for brake grinding or vibration before highway speed makes the problem expensive.
Fluids and leaks
Check engine oil level, coolant level when cold, brake fluid, washer fluid, and visible leaks. Dark, burnt-smelling, milky, or glittery fluid is a reason to ask questions before a long trip.
Electrical readiness
Weak batteries often fail during temperature swings. Slow cranking, flickering lights, corrosion at terminals, or a battery warning light should be checked before travel.
What to do if a light appears on the trip
Steady warning lights may allow careful triage; flashing warning lights, overheating, oil pressure lights, or severe drivability problems are stop-now signs. Continuing can turn a small issue into engine or catalyst damage.
When to call WrenchWiz
If the vehicle has warning lights, starting trouble, brake concerns, overheating, electrical symptoms, or an uncertain used-car history, call or text WrenchWiz Auto with the vehicle, symptoms, location, and photos. Educational tips are useful, but proper testing protects your wallet.
