Seals, Belts, Pumps, and Tensioners

Camshaft SealSo,  the time has come to change the timing belt on your ’95 Civic EX and you’ve made the smart choice of buying a timing belt kit from

You notice that the kit includes both camshaft and crankshaft seals, a water pump and gasket, tensioner, valve cover gasket,  valve cover bolt grommets, spark plug tube seals, drive belts, and timing  belt. Wow! And you thought you were just replacing a belt!

The fact is that replacing your timing belt is the perfect opportunity to replace all of these parts and that is why your timing belt kit includes them. These are wear parts (parts that are expected to wear out over time) and are easily accessible during a timing belt change.

Camshaft and Crankshaft Seals

Likely the most difficult to replace are the camshaft and crankshaft seals. While you may have read that you do not need to replace these seals, you should. If the seals fail, oil may leak onto the timing belt causing slippage and premature wear, and you will have to replace the belt again.

Water Pump and Gasket

Since the water pump is driven by the timing belt, if you don’t replace the pump now, and if it starts leaking later, you will wind up having to remove the timing belt again to replace the pump. Essentially paying the same labor costs later that you are paying now for timing belt replacement.


While your timing belt tensioner may not need to be replaced on your fisrt timing belt change, if you choose not to replace it, be sure to inspect it thoroughly, A loose tensioner, or one that does not spin freely will prematurely wear your timing belt and potentially cause it to derail.

We recommend replacing the tensioner every time you replace the timing belt. Ans if you do not replace it the first time, it should be replaced the next time around.

Valve Cover Gasket, Spark Plug Tube Seals, and  Bolt Grommets

Typically, you will need to at least loosen the valve cover to remove the timing belt cover. It makes sense to go ahead and remove the valve cover and replace the gasket. Naturally, if you remove the cover, you’ll want to replace the grommets as well.

The spark plug tube seals are designed to keep oil out of the spark plug wells and are easily replaced once the valve cover is off.

Accessory Belts (Drive Belts)

Drive belts run important vehicle accessories like your alternator, power steering pump, air conditioning and — in some cases — your water pump. In vehicle’s equipped with a serpentine belt, failure will leave you stranded.

Like the other parts in your kit, it makes sense to replace these parts when changing out the timing belt.


While all this will take a little more time, it is not overly difficult and could save you from having to access these parts at a later date. As was stated earlier, proper engine timing requires that many parts work together and failure of onwe part can cause the failure of others. We figure, better safe than sorry.
