Oil & Air Filter Change:

It is recommended that you have your oil changed every 3,000 miles. While your oil change reminder light may not activate until it reaches 7,000 or even 10,000 miles, the excessive amount of sludge buildup may cause some issues with the engine later down the road. Instead, having it changed every 3,000 miles means keeping your engine running smooth and limiting potential repair issues to the valves, push rods, rocker arms, crankshafts, and more. It is a small price to pay to keep from big expenses later.

In the Johnson City, TN area, the dust and dirt from driving on both city and dirt roads can build up in your air filter over time. This means that during regular inspections we can replace your air filter and cabin air filter so that you and your engine can take in the air that it needs.

Spark Plug Replacement:

Changing out the spark plugs every 60,000 to 100,000 miles can keep your engine firing properly which means that it reduces wear and tear. While some studies suggest that 100,000 miles is recommended for the iridium-tipped plugs, practical experience has demonstrated that the buildup in engines can begin to affect their performance much earlier.


Timing belt needs replaced

Timing Belt

The timing belt undergoes a considerable amount of wear in your vehicle as it is being turned by the engine when in operation, undergoes the heat that is inside the engine compartment, and subject to the temperature extremes of summer and winter. A timing belt that breaks may cause considerable damage to your engine because the pistons may collide with the valves and put the critical components of your engine at risk. By replacing your timing belt before it begins to wear down, you may avoid an expensive repair. Most timing belts last from 60,000 to 90,000 miles, so be sure it is replaced before the worst can happen.


Sludge build up can result from dirty oil and oil change procrastination or extended time between oil changes.

Timing Chain

If your vehicle has a timing chain, then it is not subject to the same stresses as a timing belt which is made from rubber. However, timing chains can slip or jump a chain link, we are seeing more tensioner and guide issue causing damage to the engine.

Water Pump

The water pump is subject to many different stresses and often will need replacement at some point in the life of the vehicle. The changing temperature that the anti-freeze undergoes in the summer and winter along with the stress of operating in a hot engine environment. Some water pumps with a plastic impeller become damaged or break loose from the shaft, will not circulate coolant any more, causing the vehicle to overheat.

For timing belt engines it is recommended that the water pump be replaced along with the belt so that it prevents slippage from occurring. For timing chains, the water pump should be replaced when there is coolant leakage visible or timing components are being replaced.

Head Gasket Replacement

Head Gasket damage is usually from engine overheating which results in the head gasket leaking and the cylinder heat possibly warping. The head gasket keeps the engine coolant, oil and combustion gasses in the cylinder head from making contact and mixing, causing a mess. This a commonly referred to as a blown head gasket. This is a fairly in depth repair and needs a mechanic shop that is familiar with the procedures and comes with a great warranty. Subaru head gasket replacements are fairly common and just one of the many car, truck and SUV’s we can repair.

Since overheating is a major cause of blown head gaskets your coolant system needs to be checked over for weak hoses, gasket or other coolant system leaks. This along with coolant flushes will help prevent this type of damage. All head gasket repairs come with a 24 month 24,000 mile Nationwide Warranty!

Major Damage

If your engine suffers major damage, such as a blown head gasket, American & Import Auto Repair can either repair or replace the engine. The main enemy of engines is excessive heat which can damage all the parts and even the core of your engine. The head gasket is designed to keep the separate cooling elements which include the anti-freeze and engine oil from mixing in the cylinder combustion. If they should mix, it spells disaster for your engine and replacement may be recommended.

If your vehicle starts to overheat, pull over and shut off the engine as soon as possible. Call a tow truck and have your car, truck or SUV taken to our shop. The expense of the tow is quite small compared to the potential cost of having major repairs or replacement of your engine. This also means that your engine should be checked for any coolant leak during regular maintenance and you should have regular coolant flushes to avoid problems. Going over the radiator and radiator hose is also recommended so that any early issues can be detected and repaired before they become major problems.
