Thanks guys for the advice. Had the maintenance done at Speedyfix last saturday. I bought the original parts from HRC. Aside from those required for the 40K maintenance, I was able to replace the ac/alt belt and front disk brakes. I had my motor oil and ATF changed and used RP. With all of these, Php 9K lang ang nagastos ko. OK yung RP !!!

.. ganda ng takbo ng CRV ko now ...
