cam belt

[willie]

I want to change the cam belt and see several makes for sale out there, just wondering if there is a recommended make.. The car is 1990 but only 72K miles and i cant find any record of it being changed.

Also is there anything else i should change at the same time ? water pump ?etc

I find the Blue Print stuff for these cars to be pretty okay. The water pump should be looked at if you are doing the timing belt. A genuine Mazda cam cover gasket is recommended. And as you have the cam over off, it might be worth checking to see if the CAS seal is leaking.

Thanks , Can I ask what the CAS is ?

It's the cam angle sensor. It has a rubber seal that is prone to leaking. It is quite easy to do, especially when removing the cam cover.

Thanks once again.

Also, I think you mentioned your car is auto? If so, you may need a crank locking tool to hold it while you loosen/tighten the crank bolt.
