how important is coolant?

[psycho]

For years, I always use 50-50 mixture ng coolant (ethylene glycol). Lately, it has become somewhat expensive. Napag-isip tuloy ako. I know how coolants increase the boiling point of water, etc. Pero, I know people who have not used any coolant for years and they seem to get away with it. How important is it really? Pwede ba anti-rust na lang ilagay ko? It's much less expensive kasi.

my car has been running for 2 years since i got it with just plain water coolant. so far ok naman. always normal operating temperature. kaya lang you have to check ur radiator every now and then para magdagdag ng water kase parang nag e evaporate din sya ng konti. and 1 thing i notice is yung parang residue nan nakadikit sa loob ng radiator. pagtagal tagal siguro mababarahan nun mga butas kaya kailangan ipa overhaul ung radiator. i think its a good thing to add 50% coolant para maganda ang maintenance ng radiator natin.

coolant is very important...

first, it has anti-rust properties. second, it lowers the boiling point of water.

by the way, how often do you change your coolant-water mixture? it shouldn't be that expensive since it should be done only every 30K km.

if you are using plain water... that would be the cause... those are minerals and whatnots found in plain water... use only distilled water.

Sabi ko na nga ba eh, hindi dapat plain water ilagay hehehehe
thanks mazda mazda.

Very Important mix mo sa distilled and coolant 50/50 but if dont want to put coolant try distilled lng..

Remember sa name pa lng ng Coolant.. hehehe..

And remember mahal ang brand new radiator.. hastle pa if mayroon ng leak dahil wlang maintenance..

Yun 1990 na corolla namin 1.6L parati tap water lang nilalagay namin di naman nagkakaproblema. Although napalitan na yata yun radiator once pero never naman sya nag overheat. Nag over heat lang nung nakalimutan lagyan ng tubig for some time.

Again, please refer to the SIMILAR THREADS at the bottom of this page, there are a lot of similar discussions na.
