Instructions on how too change the water pump(and therefore the timing belt)on a 97 Honda CR-V ... Is there any manuals posted online ... ??

Depending upon the authority of the person who told you the belt needs replacement, it may or may not be true. If your '97 CR-V is running with the original belt, it is way past replacement time.

Nancy, the Honda recommendations are to change belt 100,000 Km/ 60000 miles or every 7 years which ever occurs first. So if timing belt has not been changed, YES change it. Check the attached links,instruction and guides, Good luck

The TDC sensor (aka camshaft position sensor) is located under the same cover as the timing belt. Incidently, the water pump is also driven by the timing belt. The process for replacement of the TDC is not difficult, just involved. Here is a link that I hope you will find helpful; It gives step-by-step instructions with photos on how to change the TDC. This is for a civic, but the setup for the CR-V is essentially the same. If you have high mileage, you will also want to check the condition of the timing belt and water pump while you have everything apart. If you decide to replace the other parts as well, you will need the associated gaskets, timing belt, water pump and belt tensioner. http://www.civicforums.com/forums/7-honda-civic-diys-civic-tech-chat/323984-diy-tdc-sensor-cmp-sensor-replacement-w-pics.html?8caa1db9f40a1e09f200d7c940d8cc64

yes the water pump is rotated by the timmingbelt

Inside the timing belt cove, water pump is runed by the timing belt, also replace timing belt while in there will save you money and time in the long run, also this engine is an interference engine will cause major engine damage if timing belt goes bad.

You mean Timing Belt??? at 105K Miles. Be sure to replace the cam and crank seals and the water pump. And adjust the valves. I would recommend the dealer or a shop that does mostly HONDA.

if want to change timing belt it good to add water pump and belt tentioners.

Not going to like my answer here, but without any expertise in auto mechanics, I would caution you to let someone else do it. In most cases, (don't know this specific car), involves removal of water pump, pretty extensive work. And often should do other work at same time.

(as an example, in 1990s Honda Accords, it was advised to change the water pump when replacing the timing belt. All of the labor was already there, just a "relatively" small charge for the water pump itself.)

Instructions to change a timing belt would be to difficult to post here. If you have a strong desire to do it yourself, get a manual like Chiltons or Hayes with instructions and pictures.

It is recommended at 60,000 find a repubable repair facility we charge @650.00 for the service with water pump,all belts and front seals
