BMW 740iL: Making Sure That the Engine Is in Great Working Condition
BMWs have this undeniable automotive sex appeal. More than just their sleek lines and curves that give them looks that kill, they also handle like a dream and have great power that can be unleashed from within. They're designed to give you the ultimate driving experience. If you want to keep your BMW 740iL going the extra mile, you must keep the heart of the vehicle pumping. Here are some basic engine maintenance tips to keep in mind:
- Remember to change oil as frequently as needed.
Don't let your oil level drop too low. Driving without enough oil can cause the engine to break down as the rotating and moving parts under the hood fail to get the much-needed lubrication, leading to mechanical wear due to friction. By changing oil regularly, as suggested by the manufacturer or as needed, you won't only keep the engine properly lubricated but also clean. This will also prevent the engine's lubricant from getting contaminated with sludge or carbon deposits, which could result in clogging. Feed the engine with just the right amount of high-quality oil to avoid problems such as rough idle, lack of power, and issues with drivability.
- Make sure your car's cooling system is doing fine.
Don't let the engine temperature rise beyond the safe levels. If it seems to overheat frequently or approach a critical temperature level quickly, then check for coolant leaks. If it's starving on coolant, top it off right away and bleed air in the system as needed. If there's enough coolant yet the engine gets too hot easily, then you may be looking at other cooling system defects such as a broken radiator, a busted thermostat, or a worn-out water pump. Fix the cooling problem right away to prevent serious damage caused by overheating.
- Check the filters from time to time.
Filters screen away gunk, dirt, debris, sediment, and other impurities that may ruin the different parts of the engine. After some, these filters may get clogged or fractured, unable to do their jobs properly. Before it comes to this, you have to check the air filter, fuel filter, and oil filter. By replacing a dirty air filter, you're allowing the engine to breathe more easily and run more smoothly. You'll also make sure that it's fed with clean fuel with a fuel filter that can effectively trap dirt and other fuel contaminants. The engine can work much better and last longer if the oil filter does well in keeping the lubricant free from grime and other particles that may contaminate other components. The filters can be checked during an oil change or a scheduled maintenance.
- Keep the engine regularly tuned up.
A regular tune-up will allow you to detect possible problems early on and fix them before they damage the engine and affect the car's drivability. The timing and engine driving belts can be checked and replaced as needed in case of defects and fractures or lack of tension. The spark plugs and wires, along with the hoses and seals, should be inspected as well and fixed to prevent engine problems and more costly repair. Think of the user manual as your automotive bible. Heed the warning signs and take note of the recommended replacement schedules.
BMW 740iL: The Superstar of the BMW E-38 7-Series
The BMW 740iL is one of the variants of the E38 model, which was actually the origin of the BMW 7 Series vehicles from 1995 to 2001. The E-38 models were available in five-speed manual or five-speed automatic transmission, but they are sold in different variants per country. Regarded as the superstar of the E38 models, the BMW 740iL is part of the E38 selection that was offered in the United States. Other options include the 740i and the 750iL.
The 3 Ps
The BMW 740iL spells POSH, POWER, and PROTECTION. Apart from its world-class style and elegance, which is expected from all BMW vehicles, the 740iL also boasts of its 4.4-liter V8 engine that ensures superior performance in all driving conditions. A limited edition Protection Line was also produced from 2000 to 2001 based on the 740iL and the 750iL platforms, which again proved the excellent safety and protection features of the 740iL variant. The existing safety specs of the 740iL were even more improved by the Protection Line’s run-flat tires, body armor, and bullet-proof glass. The limousine version of the 740iL variant proved the vehicle’s posh nature. This very rare European long-wheelbase model was known as the BMW L7.
The BMW 740iL over the years (1995-2001)
The production of the BMW 740iL started in 1995. Originally, the 740iL had an M60 4.0-liter engine. When 1996 came, this standard engine was dropped and replaced with the all-new 4.4-liter V8 engine. During the same year, the 740iL, together with E38 variants, received the traction control as well as the Steptronic as its standard features. The Dynamic Stability Control or the DSC III feature became available for the BMW 740iL in 1997.
The next engine upgrade after 1996 came in 1999 when all the 740 variants shifted to the VANOS-equipped M62TU V* engine. The horsepower stayed at 282, but the torque significantly increased to 324 lb·ft. The millennium gave the 740iL some new standard features. These include the enhanced audio entertainment system with DSP and 6-disc changer, Xenon HID headlights, GPS navigation, sensor-controlled windshield wipers, and headlamp washers. In the same year, the 740iL had a sport package, which had the same physical attributes as the 740i. BMW decided to stop the production of E38 models, including the 740iL and the 740i, in 2001. It was then replaced by the E65.
The 740iL’s rise to fame
Although its superb specs are enough to make it reach its superstar or celebrity status, the BMW 740iL still owes much of its popularity to the Hollywood films that featured its prowess. Some of these films were Fun with Dick and Jane, Invictus, and Enemy of the State. The most talked-about cameo of the 740iL is probably on the James Bond movie Tomorrow Never Dies. Although the label was 750iL, the vehicle that was used was actually a re-badged 740iL. The sixteen BMW vehicles used in the film were customized so that driving from the backseat is possible. Most of these cars were gone, but the sole survivor stands at the Museum Industriekultur in Nuremberg as part of the “Top Secret” exhibition.
