Running without radiator caps???

[muskabeatz]

good evening tsikoteers newbie lang po ako and ask ko lang kung may masamang effect ba itong pagtakbo ng walang rad caps? kasi itinakbo ng bro ko yung car namin kagabe mula binan to cavite and nung magpakarga sya sa petron pinacheck nya yung tubig pero sad to say hindi ata naibalik ng gas boy yun radiator cap and hindi din alam ng bro ko na ganun.. nakauwi naman sya ng walang problema pero ngayon lang inilabas nya uli yung oto to sta.rosa laguna then nun pabalik na sila nanotice nila na biglang tumaas ng sobra yun temp so chineck nila agad and ayun wala na nga yung rad cap.. idinaan nila sa isang gasoline station and sabe naman na maiiuwi pa yung oto kaya lang dapat mabagal lang takbo.. ngayon medyo worried lang ako na baka may masamang epekto itong ngyareng ito.. bukas ako bibili ng rad cap para magamet na ulit? so ok lang po ba yun wala po bang masamang epekto yun balik to norman ba pag nakabili na ako ng rad caps? thanks in advance po and more power to tsikot!!!

nangyari na sakin ito. buti hindi nahulog yung rad cap habang tumatakbo ako. buti kabibili ko lang ng wilkins.
effects:baka masira block?

I guess meron effect, pa check mo na lang to be sure...sobrang naubusan na ng tubig yan, kung yun defective nga na radiator cap eh sobrang nagbabawas na ang tubig yun wala pa kaya...hehehe

wait mo na lang mga expert dito kung ano dapat pa check

ok lang yon - the cooling system of your car/vehicle won't be efficient - puwede yan no aircon and don't race your engine (hi rpm). Kung walang traffic and gabi naman no problem yan. PLUS if he was watching his temp gauge na hindi magredline ok lang.

[Yoda]

When you said, "biglang tumaas sobra yung temp," how high was it exactly? Did it boil over? Kung hindi naman, then you should be fine. No caps or even defective ones lowers your cooling system's efficiency very drastically, as what you've just experienced. But if you didn't overheat, then just buy a new cap and rest easy. ;)

normal lang iyun pag taas ng temperature dahil natatapon iyun tubig sa radiator... kailangan makuha muli radiator cap sa pinagkargahan or bumili ka ulit ng bago... hirap na baka maubosan ng tubig ang radiator at bigla kakatok ang makina. gastos sa overhaul.

I had this bad experience before sa previous mekaniko ko. When I had him do something with the car, and I picked it up after office hours, I immediately drove the car pauwi. Na notice ko na lang when I was already halfway home (around 20 kms na tinakbo), umuusok na ang harapan ng sasakyan ko, but when I checked the temp gauge at midpoint naman. I immediately parked the car, and opened the hood, lo and behold the radiator cap was not properly put on. Naubosan na pala ako ng tubig. What I did was that I placed water (mdyo nagiispill nga e). I don't know if it was the right thing to do during that time, pero nagpapanic na ako coz medyo madilim na na lugar yun and walang masyadong katao tao. Sa awa ng diyos nakauwi pa naman ako. The following day I talked to the stupid mechanic, and he admitted it. Sad for him he lost a customer because of what he did.

Pero one thing I notice lang is that jeepney drivers here do not place a radiator cap sa mga sasakyan nila. They just refill water from time to time.

let the car cool down first before adding water otherwise magkaroon ng thermal shock iyun engine at possible mag crack ang engine block...

mga jeepney wala nga sila radiator cap, pero masdan niyo everytime nag stop sila ng matagal karga karga sila ng tubig...

Iba naman sir ang radiators ng mga jeep at masyadong mga oversize yan unlike sa mga kotse na sobrang liit.

Pero as long tumatakbo yan ng maayos at di naman nag overheat after mo lagyan ng tubig ay ok lang yan. Sisirit kase ang tubig nyan pag walang takip .. ang nakakatakot lang kung minsan ay madami talagang bad effects ang overheating and worst is tamaan talaga ang engine pero depende naman talaga yan.

but it I think your case should be alright since umaandar naman kotse mo, obserbahan mo na lang.

oo nga noh!!! heheheh ang radiator cap nila is basahan lang...hehehhe

mas mabilis mag evaporate at natatapon ang tubig pag walang radiator cap. Delikado sa overheat.

May mga old cars na tumataas ang temp pag di puno ang radiator.

The adverse effects of running without your radiator cap, you've already experienced.

The cooling system is designed to run under pressure.

This is the reason why you should not fill the coolant reservoir completely since once the mixture heats and expands in your system, the excess will go to the reservoir and once things cool a bit, it sucks the excess back into the system.

This will not work effectively if there is no pressure.

Replace your missing cap as soon as possible and be careful to avoid the same situation in the future.

Hope this helps.

ibili mo na ng cap baka may masira pa sa tsikot mo, P90 lang yung silicon-type na radiator cap sa auto supply.

[userfriendly]

Buy a new radiator cap. Mura lang yan. Kung walang cap, ubos ang tubig at overheat ang resulta.

Radiator caps also acts as a pressure relife valve. It also increases your coolants boiling point to around 126 Celcius. Here is the explanation:

wow thanks sa inyo guys overwhelmed naman ako sa mga replies.. anyways nakabili na ako ng rad cap and observe ko muna kung ok naman yung sasakyan hopefully wala naman maging problema.. thanks ulit!!! more power to tsikot!!!

[sirmykel]

buti hindi umusok yung harapan mo (boil-out) delikado yun

[moe]

if you're looking to replace your old oem caps, i highly recommend federal mogul. im using them on our 3 vehicles. hth

[speedyfix]

if it doesn't exhibit any weird behavior then it should be ok.

[t2erns]

theory: kung bakit kailangan pressure tight ang engine cooling system (that includes the rad cap). plain water and at atmospheric pressure will boil sa 100 deg C, raising the pressure will raise the boiling point (boyle's law ba un or charle's law he he forgot ko na). kaya kailangan pressurize ang system and adding coolant will also raise the boiling point.

saan ba makakabili ng radiator cap?
