If the engine was running and suddenly stopped of its own accord (excuse the pun), especially if accompanied by noise from engine, it is almost certain that the engine has been seriously damaged i.e. is the mechanic saying that the timing belt has broken or that you should have it replaced before it breaks?
If the mechanic's comment was made as an observation after curing the original failure to start - have the belt changed before you drive any further.
Wilke339's answer:
The Honda literature states that the 4 cylinder is an 'interference' engine, meaning damage was done to the valves if the belt broke. But there is plenty of info online that it is not actually an interference engine, and I'm familiar with at least two cars that broke belts that did not damage the valves at all.
when it needs to be replaced
No. All 4 cylinder Honda Accord's up to and including 2002 use a timing (cam) belt that must be replaced. 2003 and newer Accord 4 cylinders has a timing (cam) chainthat requires no maintenance. All V6 Accord use a belt that must be replaced.
Timing chains on Hondas are replaced at engine rebuild time, and no sooner.
On a 1994 Honda Accord, the brake lamp comes on when a tail light is no longer working. The burned-out bulb needs to be replaced. The brake lamp will not come on after the bulb is replaced.
it has a leak and needs to be replaced this may be due to corrosion
The manual states that the timing belt on a 2004 Accord V6 should be replaced at 105,000 miles.
No, it is mounted in the fuel tank and should last the life of the fuel pump. It is replaced when the pump is replaced.
You don't. It has a permanent fuel filter mounted in the tank. It is only replaced when the fuel pump is replaced.
Most small passenger cars are torqued to 80 ft/lbs by mechanics.
The mileage that a v6 Honda Accord will need to get its timing belt changed is between 90,000-100,000. However, some mechanics recommend 80,000-90,000 miles.
Reasons your 1999 Honda Accord is overheating can include a leak in the water hose, a blown head gasket, or the radiator cap needs to be replaced.
You need to have the main relay replaced. I did that with my 1992 accord. ask around if you don't believe me. good luck. ro
