The engine sound is very loud. My mechanic told me the water pump is not function well.
The replacement for changing water pump - OEM is about $400. Have someone replace new water pump? My mazda6s, 06 has only 55000 miles.

 

water pump, belt and tensioner install

FYI, dont use a jaw puller to remove the pulley. Use a pulley remover.

Enjoy!

 

My car still in my mechanic shop. He could not find the tool remove water pump. He told me he is going to buy used tool to remove the water pump.

 

The dealer told my mechanic order the special tool cost $400 and need 10 working days. He did not buy it since I am the only mazda6s driver in his shop. He found the information of tool from web. Someone made new tools for him which cost $200. He charged me $417. I think the parts from dealer is around $200-250.

Just don't understand why Mazda 6s (v6) need buy the special tools to remove old water pump. I think the most expensive items for v6 maintenance are water pump and fuel pump. I replaced both items. I hope both new parts can last 5 years.
