MG Montego

The Austin Montego is a British family car that was produced by the Austin Rover subsidiary of British Leyland (BL), and its successors, from 1984 until 1995. The Montego was the replacement for both the aged rear driven Morris Ital and the front driven Austin Ambassador ranges to give British Leyland an all-new competitor for the Ford Sierra and Opel Cavalier. On its launch, it was sold as an Austin and also an MG. From 1988, it was sold without a marque following the phasing out of the Austin name. The Montego was launched on 25 April 1984. It was initially available as a four-door saloon only, filling the gap in the range left by the discontinuation of the Morris Ital saloon two months earlier. However, it would be produced alongside the Ital estate until that model was axed in August 1984.

MG Montego FAQ's

How do I check and adjust the tire pressure in my MG Montego?

To check the tire pressure in your MG Montego, use a tire pressure gauge and remove the valve cap from each tire. Press the gauge firmly onto the valve stem and read the pressure displayed. If the pressure is below the recommended level, add air until it reaches the proper PSI. If the pressure is too high, release some air using the tire valve. Repeat this process for all four tires.

How do I check and top up the engine oil in my MG Montego?

To check the engine oil level in your MG Montego, park the vehicle on level ground, wait for the engine to cool down, and locate the dipstick. Remove the dipstick, wipe it clean, reinsert it fully, and then remove it again to check the oil level. If the level is below the recommended range, add the appropriate type and amount of oil as specified in the owner's manual. Be careful not to overfill the engine oil.

How do I replace a blown fuse in my MG Montego?

To replace a blown fuse in your MG Montego, locate the fuse box, which is usually located in the engine compartment or under the dashboard. Identify the fuse corresponding to the malfunctioning component by referring to the fuse diagram in the owner's manual or on the fuse box cover. Using a fuse puller or a pair of needle-nose pliers, gently pull out the blown fuse and replace it with a new one of the same amperage rating.

How do I reset the maintenance light in my MG Montego?

To reset the maintenance light in your MG Montego, turn the ignition switch to the "ON" position without starting the engine. Locate the "Reset" button or knob on the instrument cluster and press it for about 10 seconds until the maintenance light starts flashing. Release the button and start the engine. The maintenance light should no longer be illuminated, indicating the reset was successful.

How do I troubleshoot a dead battery in my MG Montego?

If your MG Montego's battery is dead, first check the battery connections to ensure they are clean and securely attached. If the connections are fine, jump-start the vehicle using jumper cables and a working battery. Once the vehicle starts, drive it for at least 30 minutes to allow the alternator to recharge the battery. If the battery continues to lose charge, it may need to be replaced.

How often should I change the engine oil in my MG Montego?

The engine oil in your MG Montego should be changed every 5,000 miles or every 6 months, whichever comes first. Regular oil changes are essential to maintain proper lubrication and protect the engine from premature wear. Neglecting to change the oil at regular intervals can lead to engine damage and decreased performance.

How often should I replace the air filter in my MG Montego?

The air filter in your MG Montego should be replaced every 12,000 to 15,000 miles or as recommended by the manufacturer. A clean air filter is crucial for proper airflow to the engine, ensuring optimal fuel combustion and performance. Neglecting to replace a dirty air filter can lead to reduced fuel efficiency, decreased power, and potential damage to the engine.

How often should I replace the fuel filter in my MG Montego?

The fuel filter in your MG Montego should be replaced every 30,000 to 40,000 miles or as recommended by the manufacturer. The fuel filter plays a crucial role in preventing contaminants from reaching the engine, ensuring proper fuel flow and combustion. Neglecting to replace a clogged fuel filter can lead to fuel delivery issues, decreased performance, and potential damage to the fuel system.

How often should I replace the spark plugs in my MG Montego?

The spark plugs in your MG Montego should be replaced every 30,000 to 50,000 miles or as recommended by the manufacturer. Spark plugs play a vital role in the ignition process, and worn-out plugs can result in misfires, decreased fuel efficiency, and engine performance issues. Regularly replacing the spark plugs is essential to maintain optimal engine performance.

How often should I replace the timing belt in my MG Montego?

The timing belt in your MG Montego should be replaced every 60,000 to 90,000 miles or as recommended by the manufacturer. The timing belt is responsible for synchronizing the engine's camshaft and crankshaft, and a worn-out belt can lead to engine damage and complete breakdown. Regularly replacing the timing belt is crucial to prevent potential engine failure and costly repairs.

What is the recommended tire pressure for my MG Montego?

The recommended tire pressure for your MG Montego is typically listed on a sticker inside the driver's side door jamb or in the owner's manual. It is important to maintain the recommended tire pressure to ensure proper handling, tire wear, and fuel efficiency. Incorrect tire pressure can lead to uneven tire wear, decreased fuel economy, and compromised safety.

What type of coolant should I use in my MG Montego?

The MG Montego requires a specific type of coolant, typically a 50/50 mixture of ethylene glycol-based antifreeze and distilled water. It is important to use the recommended coolant to prevent freezing, boiling, and corrosion within the cooling system. Improper coolant can lead to overheating, engine damage, and potential coolant leaks.

What type of transmission fluid should I use in my MG Montego?

The MG Montego requires a specific type of transmission fluid, which is Dexron III/Mercon ATF. It is important to use the recommended fluid to ensure proper lubrication and smooth operation of the transmission. Using the wrong type of fluid can lead to shifting issues, increased wear, and potential damage to the transmission.
