Truck won’t start… again? 🔋

A battery that keeps dying is usually caused by age, a drain, a charging problem, or loose or corroded connections. Louisiana heat is tough on batteries, too.

A dying battery can leave you stranded, so don’t just keep jump-starting it. Our Ross Downing GMC service team in Hammond can test your battery and charging system.

Towing, summer heat, stop-and-go traffic… your cooling system works hard. 🌡️

If your temperature gauge climbs, don't push through it. Driving while overheating can blow a head gasket, warp the cylinder head or ruin the engine.

Turn off the AC, pull over safely and shut it off. Don't open a hot radiator cap. Then have it towed or checked.

Our Ross Downing GMC service team in Hammond can track down the cause.

Is synthetic oil worth it? 🛢️

For most newer vehicles, yes, and many newer engines call for it. Pulling a trailer with your Sierra? Stop-and-go traffic? South Louisiana heat? That's when synthetic's extra protection matters most.

Check your owner's manual for the right oil, and follow your oil life monitor. Our Ross Downing GMC service team in Hammond can take care of it.

How often should you rotate your tires? 🛞

For most vehicles, about every 5,000 to 7,500 miles, and it often lines up with an oil change. Check your owner's manual for your exact interval.

Rotating evens out wear so your tires can last longer, and it matters even more on AWD and 4WD vehicles. South Louisiana heat and potholes are hard on tires, so check your pressure monthly when the tires are cold.
