99 corolla xe 1.3 atrocious gas mileage

[voltscastillo]

lovelife body...

kotse ng misis ko. 67,000km sa odo. absolutely stock and still sariwa. the only thing i've done is replace a stuck up a/c compressor with a surplus compressor. the a/c tech then said ayaw na mag automatic so nilagyan ng ibang thermostat that clicks on and off.

ito kya yung cause ng high FC? measured it 3 times already, it's only 4-5 km/lit. i might as well be driving an expedition.

at wala pa hatak.

something's wrong i know it... changed the filters, oil, spark plugs, alignment... ang hindi ko na lang nagagawa yung pa adjust yung valve tappets sa toyota, which the service advisor said was not unnecessary (?).

any ohter ideas? short of removing the temp a/c thermostat?

[kumagbehota]

ang coimpressor pag hindi tugma sa load ng makina talagang malakas sa gas, either overworked sya unnecesarily or underpowered yung makina relative sa compressor, pa check mo muna, at yung sabi ng SA mo?

"said was not unnecessary (?)."

pag ganyan necessary pala yun....

said was not unnecessary (?)."

pag ganyan necessary pala yun....

Hehehe, a clear case of double negatives, leading to a positive result.

Re: fuel problem, have another A/C technician double check your compressor. For sure, nandun ang problema.

kamusta naman ang FC kung hindi ginagamit ang AC?

[voltscastillo]

hehe. sorry i meant "not necessary"... typo my bad.

FC without a/c seems the same, but i haven't measured it yet. pero prior to the installation of the surplus compressor, ganda yung FC nya. nasa 9-10. yun nga parati namin gamit kasi matipid.

binalik ko na sa nagkabit sabi nya pareho lang daw sa lumang compressor yun, only diff was, surplus japan yung compressor. i'm guessing na baka compressor ng camry yun eh, kasi ang lakas talaga: bilis at consistent yung bomba ng freon kasi ang lamig lamig, beats the old old compressor even when it was new.

yun nga lang, lakas talaga sa gas.

may differences ba ang compressor power across all corolla model ranges ng toyota? e.g., higher power yung sa 1.6 engine vs. 1.3 engine? para kasing pare-pareho lng itsura nila sa akin eh.

Baka malaki ang inilagay na compressor sa iyo bro. The size of the compressor also affects fuel consumption . . . Compare mo sa iba repakol ang size ng compressor.

[speedyfix]

normally kahit gaano kalaki compressor mo di ka naman dapat aabot sa ganyan milage. have the carb checked. kung wala ka hatak it's normally that which causes it kung maayos naman timing and tappets mo.

[rion]

baka naman kumakabit parin yung compressor kahit naka off na yung A/C?

[speedyfix]

even then i don't think it should suffer that much.

hmmm... time to overhaul the carburettor na kaya bro?

and it is true na yung engine nito needs no tappet adjustment? parang hindi ako makapaniwala eh, considering it's still carbed, e yung hondas ko FI na lahat kelangan pa din i-adjust....

[voltscastillo]

baka naman kumakabit parin yung compressor kahit naka off na yung A/C?

yep i thought about this na... what i did was to turn off the main thermostat sa dashboard, and the thermostat installed by the aicon guy, then tried driving around. wala, compressor doesn't come on (a/c fan ON ha). when i turned on the main thermostat, wala pa din. when i turned on the aircon guy's thermoswitch, ayun, umandar, hehe.

na-bypass na talaga yung main thermostat nung aicon guy hehe.

[speedyfix]

yup i can be adjusted. have that checked narin baka maluwag na. if that still doesn't improve the milage then have the carb looked at na.

walang kwenta ang mga surplus compressors kasi you will just need to replace every time it becomes defective. palpak yang mga yan whether it's from banawe or evangelista. nakadalawang palit kami. yung 1st comp. namin tumatagas ang freon. yung 2nd comp. di rin namamatay para mapahinga yung engine. the same
problem that you have right now - an aircon that does not automatically turn off
after a few minutes of use. the aircon must also automatically turn off when you accelerate fast after pressing the gas pedal hard. that's why we opted to install a brand new compressor. talagang magastos yan sa gas kasi the engine no longer rests when it's turned on. mga 20thou nagastos namin kasi we had to replace some parts which were probably affected by the dysfunctional compressor. mitsu lancer auto namin
