annoying sound: water pump or tension bearing or what???

civic esi

kakaayos lang ng crankshaft pulley bolt. but even before this, meron nang annoying sound (parang kumukulo type of sound) na dinig sa driver side kung nasa loob ka ng car or dun sa side ng power steering pump/timing belt pag sa engine bay ko papakinggan.

pinalitan na ng mekaniko yung tension bearing (sa timing belt) just 2 weeks ago pero andun pa din ang sound at lalo pa siya lumakas.

any idea kung san galing yung sound? iniisip ko kasi is baka naman sa waterpump??? possible kaya na sa crankshaft pulley siya?? wag naman sana....

tnx!!!

you can tell if the pulley is busted if it wiggles. if it does then this is probably causing the noise. it's easy enough to tell naman. just keep taking out belts one by one till the noise diasappears. once you've pinpointed the problem, fix it

try checking idler pulley bearing and a/c compressor bearing ... these were the items i replaced on my esi

a handy plastic tubing is useful for troubleshooting such noise ... you can locate the offending bearing with precision

ok tnx!!! will try the "stethescope" method para ma isolate yung source of the annoying sound.

suspetsa ko din pulleys pero wag naman yung sa crankshaft at mejo mahal siya. magkano kaya yung surplus nun???

yung sa compressor, pag sira ba yung bearing sisingaw ang freon??? kasi although nagpalagay ako ng freon some 5 days ago, ndi naman siya ubos talaga. mejo mahina lang lumamig kaya ako nagpalagay. so possible na ndi yung compressor bearing ang busted.

san yung idler pulley???

tnx!!!

tanong lang, nawawala ba siya pag inapakan mo ang clutch?

hindi pa sisingaw ang freon kung noisy lang yung compressor bearing ... but you have to replace the bearing asap before it disintegrates and damage the whole compressor ... if the bearing is available at hand, replacement procedure would only last a couple hours ... ibababa kasi ang compressor and of course freon/oil refill din ... mang mario is your best friend for this service

idler pulley is the one used to adjust tension for the aircon belt ... just look where the aircon belt runs ... you can see the adjusting bolt at the top of the idler assembly ... madali lang palitan ang bearing nito ... pwede diy

in my case, the compressor bearing was replaced after 10 years (160,000km), the idler bearing was replaced twice during same period ... note that if the belt tension is adjusted correctly, the bearings and the belt will last a long time

mr afrasay, automatic transmission po yung kotse. sorry, i did not mention sa previous post.

nway, salamat sa mga advice. ang plano ko is to check isa isa yung mga possible sources of the sound. maybe i can do this by loosening the belts then checking the moving parts one by one. ok lang ba ito lalo na kung start ko din yun engine (for a short period of time lang naman)???

dun pala sa compressor, andun pa din ang tunog kahit ndi naka on ang aircon. so possible ba na sa compressor bearing pa din ang problema??? dito ako prvince kaya baka malabo si mang mario unless sadyain ko siya.

will update about the situation after this weekend. tnx!!!

Sakin may humming sound PEro mawawala kpag na tapakan ko ng gas pedal.. parang ang baba lng ng MInor i think.. what do u think afrasay?

**seonadancing** · April 1st, 2006 04:26 PM

Yun pinaayos ko yun aircon ko, yun compressor oil seal yun sira and nung bago ko pa pinaayos meron sound na parang ungol tapos mawawala then minsan meron ulit. Nuubusan din ako ng freon nun e so baka pareho yun problema natin.
