Repair Mistakes & Blunders
Repair Mistakes & Blunders

One icy winter evening, the family set out in our ’68 Catalina. The Pontiac had a “miss,” which we noticed before, but had not diagnosed. After a few miles, the miss became more pronounced and rather than chance breaking down on a cold night, we decided to return home. Once home, my dad opened the hood, saw dripping fuel from a fuel line burst into flames and quickly ran for a fire extinguisher. Unfortunately, it was too little, too late. By the time the fire was doused, the wiring, tires and everything else in the front end had gone up in flames. The keys even melted in the ignition. We reported the incident to the insurance company, and they agreed to send a tow truck sometime in the next day or so.

The following morning, our next door neighbor was having trouble starting her car and called her roadside assistance service to check the battery. Later that day, a tow truck came up our driveway, and the driver asked my mother, “Is this the car?” while pointing to the burned out Pontiac. She said "yes," thinking our insurance company had come to tow the car. He pensively walked around the Pontiac's carcass, looked at the burned tires and melted dash, lifted the scorched hood and replied, “Lady, I don’t think I can get this started.” The tow truck driver was at the wrong house.

Frozen Batteries
Tom's Story

Battery charger owners manuals warn, "Do not charge a frozen battery." The altered chemistry/conductivity inside a frozen battery may trick the battery charger into indicating the battery is fully charged and healthy when it is actually discharged and full of ice.

But, when does a car battery freeze? The battery does not freeze when I leave my car parked outside when it is 40 below. (-40 F happens to equal -40 C, and it is also frequently the temperature in my wife's home town in northern Minnesota.) Do I need to drive north in Canada until I find temperatures that will freeze a battery?

Inside a conventional car battery is a mixture of acid and water. When the battery is fully charged, the acid/water mixture will not freeze as long as the temperature is above about -70 F (-57 C). In a discharged battery (anything below 12 volts), pure water separates out from the acid/water mixture. The temperature only has to drop to 32 F (0 C) to freeze that water.

AutoMeter and Bosch battery chargers

If a conventional car battery is likely discharged and the temperature is below freezing, then assume the battery is frozen. Remove the battery from the vehicle and take it somewhere warm where it can thaw out before trying to charge it with a battery charger.

The absorbed glass mat (AGM) car batteries RockAuto sells do not have that acid/water mixture sloshing around inside and are much more resistant to cold, even when the battery's charge drops below 12V. Something that avid shoppers may have noticed is that the AutoMeter and Bosch battery chargers we carry (under "Tools & Universal Parts") have "AGM" charging modes. The AGM mode on the newest battery chargers often (photo on right) is for AGM batteries OR conventional batteries at cold temperatures (Bosch defines cold as less than 41 F (5 C)). In AGM mode, the battery charger creates a slightly higher voltage to help the AGM or chilly conventional battery charge a bit faster.

Brian's Factory Five Racing Mk3 Roadster
Brian's Factory Five Racing Mk3 Roadster

This is my Factory Five Racing Mk3 Roadster built in 2009. I purchased it in 2017 from the original owner. My wife supported this endeavor in celebration of my recent advancement to Chief Petty Officer (E-7) in the US Coast Guard. She said it would also serve as my birthday, anniversary and holiday gifts for the foreseeable future, which was absolutely fine by me.

Like most hobbyists, I wanted to freshen up a couple things and change others to my liking. With the drivetrain and suspension primarily comprised of 1987-2004 Ford Mustang parts, RockAuto has been an excellent source for high quality parts at low prices. I have purchased engine gaskets, spark plugs, hoses, clamps, belts, a speedometer cable, sensors/solenoids and brake pads. Thank you again for offering a wide variety of quality products for the budget-minded consumer.
