Timing is usually checked once during a complete tune up.
The main features that determine whether an engine is air or liquid cooled include the cooling medium used and the design of the cooling system. Air-cooled engines rely on ambient air to dissipate heat, often utilizing fins to increase surface area, while liquid-cooled engines circulate coolant through a closed system involving a radiator and water pump. Additionally, air-cooled engines are typically simpler and lighter, whereas liquid-cooled engines provide more efficient temperature regulation and can handle higher power outputs. The choice between the two often depends on the application and performance requirements.
the first airplanes used engines very similar to ones found in automobiles, later aircraft often featured air cooled rotary engines for their light weight before being replaced by jet engines.
CR-V engines are equipped wiht timing BELTS not chains. The factory recommended replacement interval is 105,000 miles.
Most Subaru models use a timing belt, often referred to as a cambelt, particularly in their older and non-turbocharged engines. However, many of their newer models, especially those with turbocharged engines and certain boxer engines, utilize a timing chain instead. It's important to check the specific model and engine type to determine whether it has a cambelt or a timing chain. Always refer to the owner's manual for maintenance recommendations.
Timing belts are commonly used in internal combustion engines, particularly in overhead cam (OHC) designs. They synchronize the rotation of the crankshaft and camshaft(s), ensuring that the engine's valves open and close at the correct times in relation to the position of the pistons. Timing belts are typically found in four-stroke gasoline and diesel engines. Additionally, they are often made of rubber and reinforced with fibers for durability and flexibility.
Steam engines are typically cooled using a combination of water and air. The steam produced during operation is condensed back into water in a condenser, where it releases heat and is cooled by circulating water, often drawn from a nearby source. Additionally, in some designs, air is used to cool parts of the engine, particularly in the case of smaller or portable steam engines. This cooling process helps maintain optimal operating temperatures and prevents overheating.
Go to your library and see if they have a Chiltons manual otherwise go to a bookstore and buy one, they are cheap. I have never worked on one of the V-6 engines but setting the timing usually involves rotating the distributor and using a timing light. I am not sure if this is the case on computer controlled engines since I have never had to set the timing on any newer car I have worked on. If it is bad and you have a lot of miles, you may have a timing belt going bad. They get loose when they get old and often jump a notch. VBD
The 2002 Ford Focus Maintenance Guide shows ( 120,000 miles ) for the 2.0 liter engines ( SOHC and DOHC )
No, a fuel injection engine does not have points in a distributor. Traditional ignition systems used in carbureted engines often employed a distributor with points to control the timing of the spark. In modern fuel-injected engines, ignition timing is typically managed electronically without the need for mechanical points. Instead, these engines may use coil-on-plug systems or distributor-less ignition systems (DIS) for more precise control.
Up through the 2001 models CR-V's are quipped with timing BELTS that the factory recommends be replaced every 10 years or at 105,000 miles, whichever comes first. Starting with (and including) the 2002 models, the engines have timing CHAINS which do not require replacement.
I was looking at the 1999 Ford Escort scheduled maintenance guide and the Gates website ( they make timing belts etc . ) and both show to inspect the timing belt at 120,000 miles , replace if necessary ( that applies to both the 2.0 liter SOHC and DOHC engines )
Most oils nowadays are 50:1. The great thing now is that an air cooled engine two cycle oil often comes in a package that mixes a gallon of gas to the correct amount. Beware of outboard motor oil as those engines are water cooled, not air cooled (heat is different.)
