Hi sifus ..Need some advise ..Recently i had discovered some water mark (water puddle) right under the those tensioner belt area ... it seems like there are water dripped out from some area near those belt .. and i am sure its not from the radiator cause its not right under the radiator. It only happens after i had stopped my car for a while and after that it will not drip anymore. Tried to check the expansion tank water level after its cool down, and didnt notice any significant drop in water level too .. Do you think this could be the issue with the water pump? If yes, is it expensive to fix it? Do i need to change some other component too? especially when the water pump is removed?Thanks and looking forward to hear from you all soon Regards,JS
