Radiator consume lots of water after short drive

[cRane01]

I noticed my car consume lots of water after a short drive. Halos ma-drain yung nasa reservoir ko, kahit tinakbo ko is around 6km lang. Galing na din akong Evangelista for overhaul ng radiator, pero same problem occurs. Kita ko naman walang leak sa radiator after nung overhaul, baka may naka-experience ng ganitong problem. Also, checked yung ilalim nung car, wala naman leak habang naka-park. I'm planning to go back to the shop tomorrow, pero baka may inputs yung mga expert dito sa tsikot.

According pala dun sa nagkabit nung radiator kanina, okay naman yung pagkaconnect nung hose and walang leak ung reservoir ko. Hindi ko talaga alam pano nauubos yung tubig kung walang leak.

Thank you mga sir

Maybe worn radiator cap gasket?

Mukang okay pa naman yung radiator cap gasket (but I'm not an expert, so I cannot tell talaga haha), pero hoping na yun yung problem. Pagbalik ko sa shop bukas papalitan ko na din yung cap, sana maayos na yung problem. Thank you sir Wh1stl3r2 sa input

Check your oil dipstick & oil filler cap. If you see mayo, coolant is mixing w/ oil....means the head gasket. Let's hope not.

No luck mga sir, hindi ko napalitan yung radiator cap. Ganun pa din consumption ng water, pero dinala ko sa ibang shop and tinaas nila yung sasakyan and sinilip na walang leak sa ilalim. Baka daw Head Gasket, sabi naman dun sa isa baka thermostat. Kaya di ko muna pinagawa, medyo kapaan pa yung issue eh. Any other input sir?

Thanks sir PMtravajante! I checked the dipstick and oil filler cap, normal naman sa tingin ko. I attached some pic for reference, if normal nga ba

Take it to a shop that has a cooling system pressure tester. It should hold at least 10% of your radiator cap rati g for at least 15 minutes

to read 110% of the radiator cap pressure rating, to hold at least 5 minutes under pressure

check mo na din iyong radiator hoses mo. sometimes meron minute holes na iyan dahil sa wear and tear

btw, gumagamit ka ba ng coolant? mas madali kasi makita ang leak kung coolant ang gamit mo kesa sa distilled water ( i hope hindi tap water ang gamit mo bos) kasi nag-iiwan ng stains or tracks kaya mas madali makita kung may leak o wala at kung meron man, easier to pinpoint

recheck tightness ng mga hose clamps..

from your description e malamang under high pressure lang nangyayari ang leak. so as jick mentioned, a pressure test is necessary para marule out ang anumang opinyon ng mga mekaniko jan sa tabi tabi.

kaso, sino ngayon ang may cooling system pressure tester?

inspect mo na rin lahat ng mga freeze plugs baka may malapit nang lumabas. makikita mo naman kung saan may traces of coolant....isa pa e dun sa water pump hole kung may tagas.

the anti freeze/coolant is usually dyed with flourescent additive. if you use an UV (black) light, it usually glows pointing to the immediate vicinity of the leak.
