Common Lincoln LS Faults
The Lincoln LS has a number of issues that limit its sporting and touring capabilities. Just browse the forums to get a clearer idea. We have compiled some of the common Lincoln LS failures.
1- Engine shutdown problems
Engine problems are fairly common on the 2004 Lincoln LS. Many owners have reported their engines shutting down without warning. There are several potential causes. The first is low fuel pressure.
If the engine is not getting enough fuel from the tank, it may stall at low speeds. The problem may be a broken fuel pump or a dirty fuel injector. Another possible cause is a bad oxygen sensor or air mass sensor. These components determine the amount of oxygen needed for the engine to run.
If there is too much or too little oxygen, the engine will not have much power . A Lincoln LS owner mentioned that the catalytic converter on his had to be replaced. If the catalytic converter becomes clogged, exhaust gases can build up inside your car and cause your engine to stall from exhaust pressure. If you’re looking to buy a 2004 Lincoln LS, be sure to ask the seller about the car’s engine history.
2- Engine failures
Several 2003 Lincoln LS owners have complained of engine failure at about 80,000 miles. An owner of a Lincoln LS discovered that his engine problem was caused by a blown valve gasket . When the gasket breaks, motor oil can leak out of the engine and onto hot vehicle components, producing an unpleasant odor.
Engine oil can get on the spark plugs, causing the engine to misfire or run rough. If the valve gasket is not replaced, it may cause a fire. It is important to maintain and follow a regular maintenance schedule to prevent this from happening. Ideally, include a routine inspection of engine parts with checking your engine oil every two weeks.
3- Overheating problems
Many owners have reported overheating problems with their 2002 Lincoln LS. One owner complained that his cooling components became brittle after 110,000 miles. This probably means that your coolant overflow tank has been compromised.
If the overflow tank fails, the excess coolant has no way to get out of the cooling system, so it spills out of the radiator cap and corrodes metal parts. The engine relies on the cooling system to control its temperature, so it will eventually overheat when its cooling components rust.
Overheating can also occur if there is a coolant leak from a punctured radiator hose or a broken water pump . Cooling system problems often occur during heavy traffic situations, as there is not enough air flowing through the system when the vehicle is stationary.
If you’re thinking about getting a 2002 Lincoln LS, be sure to check your cooling system to avoid unexpected overheating issues.
4- Timing chain failure
Some 2000 Lincoln LS owners have reported engine problems caused by bad timing chains. Over time, timing chains can become loose from normal operation, causing them to skip a tooth or break.
A bad timing chain can hit engine timing and lead to numerous problems, including engine misfiring and decreased fuel economy. A bad timing tensioner can also be a factor causing engine problems.
Without the tensioner, timing chains can fail prematurely. These are just a few examples of 2000 Lincoln LS engine problems. If you’re experiencing any of the symptoms we’ve listed, we suggest you take your car to a shop for a full diagnosis.
Overall, the Lincoln LS remains an excellent choice for drivers who want luxury without paying 5 Series prices. We hope this helped you decide if this luxury sports sedan is right for you. Before finalizing your purchase, we encourage you to do your own research and ask sellers about your car’s repair history, so you can determine potential issues.
