HOw to install vacuum gauge

[adventure]

mga friends tanong ko lang po sa inyo kung puwede po ang vacuum gauge sa diesel engine gusto ko po kasi kabitan kotse namin by the way makina po pala namin in 4d55 mitsubishi san po ba ikakabit yung vacuum hose

while engine is running, unplug and check small hoses and check if it's vacuum...

then you can hook it there with a "T" or better trace it up to the source (vacuum pump) and hook it there... the "T" comes free when you buy the guage...

make sure you buy a vacuum/boost gauge. so dual purpose...

para san bayun vacum?

dun sa idle up switch pede ikabit yun vacuum gauge. basically it tells you the amount of air that is being suck by the engine. the more air, the more fuel is injected to the engine. it also serves as a consumption gauge sa mga euro cars like bmw and mb.

sir afrasay san po ba yung sinasabi niyo po na idle pump ba yun kasi po nung chineck ko yung injection pump na may hose sa air wala po siyang hangin dapat po kasi daw kapag naka start makina at binunot yung hose tataas yung minor and magiging palyado and wala din pong nangyari help naman po

Sir adventure, post nalang po pic ng makina.

Afaik on later diesels, nag ba-vacuum na yung hose on idle. puwede mo silang tangalin para macheck kahit engine running on idle. kahit boost hose mo yung natangal ok lang, walang problema.

like sir afrasay said, "basically it tells you the amount of air that is being suck by the engine"

It also tells how's your vacuum pump's condition, since some vehicle's brake also relies on the vacuum pump.

I read ago somewhere that the vacuum guage also tells you how is your automatic tranny's condition on gear shifting. for some vehicles a/t are also controled by the vacuum level... I don't know if common Japanese vehicles also works like this...
