Draining and refilling the coolant is one of the easier maintenance tasks you can do on most vehicles. In addition to saving money, doing your own maintenance is a way to monitor the health of your vehicle.
Coolant loses effectiveness over time, so it’s important to periodically drain and refill the cooling system. In addition, as coolant becomes dirty, and rust and particles can eventually degrade cooling system components, such as the engine and water pump.
If you drain the system and then pour coolant in, there is still air trapped within the hoses and components that hold coolant. That air must be removed. You’ll need to bleed out the air and then top off the coolant to the proper level.
Some car manufacturer refill procedures use a special tool that automatically fills the cooling system and bleeds any excess air. In most cases, if you don’t have the special tool, you can still fill the cooling system and bleed it manually. In rare cases, vehicles need to be serviced with specialized cooling system equipment, due to the complexity of the cooling system. Air will become trapped in the cooling system, and cause the engine to overheat! Check the service information before you attempt the procedure.
Research the vehicle’s cooling system.
Caution
Do not work on the coolant system when the system is hot and under pressure: Coolant can cause serious burns. Do not remove the radiator cap, cylinder block drain plugs, or loosen the radiator draincock, when the engine is hot.
1. Tighten the radiator draincock.

2. Tighten the cylinder block drain plug(s).

3. Fill the cooling system with the manufacturer-specified antifreeze. You can find the correct specification in your Chilton DIY subscription or in your owner’s manual. Because specifications change occasionally, such as with new technology, it’s a good idea to check the technical service bulletins in your ChiltonDIY subscription too.
4. Fill the radiator to the top and install the radiator cap. Add sufficient coolant to the overflow tank to raise the level to the FULL mark. Check your Chilton DIY specifications or the owner’s manual for the coolant amount including the overflow tank.

5. Run the engine with both the radiator cap and reservoir/overflow tank cap in place. Turn on the heat with the blower on high. When the engine reaches normal operating temperature, shut the engine off and allow it to cool.
6. Top off the coolant level to the reserve/overflow tank as necessary to bring it to the FULL mark. Only add coolant when the engine is cold. The coolant level in a warm engine will be higher due to thermal expansion – that is, hot coolant expands and so the coolant level will appear to be higher.
7. Repeat the procedure and recheck the cooling system level.
Throughout the history of American transportation, cross-country migration had been based on three things, imperialism — to conquer new lands and expand the country’s boundaries; on necessity — to farm land and achieve prosperity; and on recreation and education — to see the sights and explore new vistas. Late in the 20th century, a new aspect of cross-country travel emerged: racing, not just getting there, but going faster and getting there quicker.
The Cannonball Run
Dan Gurney and Brock Yates
Known officially as the Cannonball Baker Sea-to-Shining-Sea Memorial Trophy Dash, the unofficial race was run five times in the 1970s and was the subject of several movies in the following decade. Car and Driver editor Steve Smith and magazine writer and racer Brock Yates devised the event as a celebration of Erwin George “Cannon Ball’ Baker’s previous record setting trips, as well as a protest against the National Maximum Speed Law being enacted in 1974 (which Yates and Smith argued was slower than the average speed of Baker’s 1933 New York City to Los Angeles trek). Yates and Smith were also inspired by various “road movies” of the late 1960s and early 1970s, specifically Monte Hellman’s Two-Lane Blacktop and Richard C. Sarafian’s Vanishing Point (both released in 1971).
Cannonball Baker Sea-to-Shining-Sea Memorial Trophy Dash vehicle: a 1971 Dodge Custom Sportsman, called “Moon Trash II”
The object of the race was simple: Leave the Red Ball Garage in New York City and be the first person to reach the Portofino Inn in Redondo Beach in the shortest time possible. There were no other rules.
The first race began on May 3, 1971, using a 1971 Dodge Custom Sportsman van called the “Moon Trash II.” The race was run four more times over the next few years. In the 1975 running, Jack May and Rick Cline drove a Ferrari Dino in a record time of 35 hours and 53 minutes, averaging 83 mph. The second race was won by American racing legend Dan Gurney (winner of the 1967 24 Hours of Le Mans) in a Ferrari Daytona. Dan later remarked, tongue in cheek: “At no time did we exceed 175 mph.”
After five runs, the official record for the Cannonball was 32 hours and 51 minutes (about 87 mph), set in the final run by Dave Heinz and Dave Yarborough in a Jaguar XJS in April 1979. Over 250 racers participated in the Cannonball Run races in anything from a Travco Motorhome (44:42) and a Honda 600 (DNF) to a Ferrari 308 (35:58) and a Mercedes Benz 450 SEL (32:59).
The race entered mainstream consciousness after a series of movies depicting the Cannonball Run debuted, all featuring illegal coast-to-coast races. Cannonball was directed by Paul Bartel and released in 1976, the same year as Charles Bail’s Gumball Rally, a more accurate depiction of the event. In 1981, Burt Reynolds joined an all-star cast in the movie Cannonball Run, based on the exploits of the original race. Cannonball Run was followed up in 1984 with a less-than-successful sequel. Both movies were written by Yates and directed by fellow car enthusiast and career stuntman Hal Needham. The movie uses the actual ambulance they both drove in the 1979 Cannonball Run (complete with a “doctor”). Speed Zone, considered the final installment of the Cannonball Run series of movies was released in 1989, and has a completely different cast (with the sole exception of Jamie Farr).
At Tire Rack One Lap of America, May 2014, via Tire Rack
After Car and Driver succumbed to the risks of sponsoring an illegal event, the editors chose to abandon any further attempts and started a successor race, the “Tire Rack One Lap of America.” Instead of a coast-to-coast straight shot, racers must compete various time trials on public roads and/or racetracks around the country. Started in 1984, the length of a typical race can be up to 10,000 miles. The 2015 event features 7 days of competition over 3245 miles and begins in South Bend, Indiana on Saturday, May 2nd.
Further Attempts
With the Cannonball Run as its inspiration, one of its former racers, Rick Doherty, organized the U.S. Express with similar aims. The only difference is that the U.S. Express terminated at the beach in Santa Monica, making it slightly longer than the Cannonball Run. The results of the 1983 race broke the previous record, clocking in 32 hours, 7 minutes by David Diem and Doug Turner at the wheel of a Mazda RX-7.
Alexander Roy
Though the U.S. Express record was never official nor was it documented or confirmed, it was still regarded as the record. Alexander Roy is an American rally driver and winner of the very Cannonball-esque Gumball 3000 around-the-world rally from England. A not-too-serious event, Roy regularly attends the rally in various police livery (in 2003 he was dressed as a Canadian Mounted Police driving a 2000 BMW M5). Roy meticulously prepares for rallies with the goal of avoiding police stops by using maps, GPS navigation, and spreadsheets. During the 2004 rally, he impersonated a police officer complete with mounted lights that he used to perform traffic stops against his competitors during the rally.
After hearing about the U.S. Express record from 1983, Roy set out to break its record in 2006. A practice run in December 2005 yielded a finishing time of 34 hours and 46 minutes, and the addition of a spotter plane. The following April ended in a fuel pump failure. The successful run took place over Columbus Day weekend in 2006 with co-driver David Maher (another Gumball rally driver). He traveled 2,794 miles in 31 hours and four minutes with an average speed of 90.1 miles. From New York to Santa Monica, he only encountered four traffic lights and four toll booths.
Dave Black, Ed Bolian, and Dan Huang
A three-man team led by Ed Bolian claims to have driven the 2,813.7 mile route from the Red Ball Garage in New York to the Portofino Inn in Redondo Beach on October 19-20, 2013, in 28 hours and 50 minutes, averaging 98 miles per hour, including the 15 minutes it took to get out of Manhattan. Driving a 2004 Mercedes-Benz CL55 AMG, and stopping only three times for fuel because the car was equipped with two specially installed 22-gallon auxiliary fuel tanks in addition to its standard 23-gallon tank, Bolian offered GPS logs as proof of his accomplishment (read more about it here: Doug DeMuro, “Meet The Guy Who Drove Across The U.S. In A Record 28 Hours 50 Minutes,” Jalopnik, 30 October 2013, Web.)
It is interesting to note that Brock Yates, the original founder of the Cannonball Run doesn’t acknowledge any further attempts, claiming, “Someone was going to get killed.”
