Honda Civic, 30K Timing Belt Replacement
Q:
I’ve been advised
to replace the timing belt on my ‘95 Honda Civic. I have 30k miles
on it. I know that if the belt breaks, I'm in trouble and the service
manager is insistent upon replacing it. This will cost $400 and includes
replacement of the water pump. I've talked to so many people and they
all tell me that it isn't necessary at 30k miles, regardless of the time
indicated in the service manual of 72 months. I've been told by the service
dept that the belt can have dry rot at 6 years, and friends of mine who
have Civics tell me that's not possible as it's enclosed and not exposed
to the weather. They advise going by the mileage recommendation of 60k
and not the age of the car. I'm so confused! Can you give me any advice?

A:
Let’s put it this
way, if you were my wife or daughter and were driving this vehicle you
would have a new timing belt, water pump along with a new camshaft and
crankshaft seal. Honda engineers are a pretty sharp lot and when they
say a component should be replaced, replace it! Timing belts not only
wear they rot/weaken with age. More often than not, the cause for timing
belt failure is not because the timing belt is worn, it has broken due
to age rot. The plastic cover over the timing belt does not stop the heat
of the engine from baking the belt and belt fibers. Over time this heat
and the constant flexing of the belt takes its toll. A new timing belt
is in order. If money is tight just change the timing belt and gamble
on the water pump. The cost of replacing the timing belt is small money
compared to the possible costs if the timing belt should fail and damage
the engine.
