I have got a honda 97 vti. Napansin ko lang lately na after a long drive, kumukulo yung tubig sa water reservoir esp at day time at tirik araw. Though yung temp ko kalahati parin just like before.

This does not happen pag gabi.

I noticed that after nag cooldown na, babalik tubig sa radiator at halos wala na laman yung reservoir, what could be wrong here? Seems like I am loosing water along the way.

I checked my fan mukhang ok naman, nag au automatic
Malamig pa rin naman AC ko

- Could it be baradong radiator? (at least yun ang sabi ng mekanik). how do I know na barado nga radiator?
- Or sirang water pump? how do I know na water pump sira?

Pansin ko rin na madaling tumaas sa half ang temp ko,,like siguro after 10 mins....ganun ba talaga?

thanks mga peeps..

Appreciate your feedback.
