Bakit advise sa akin nung isang mechanico eh mas maganda daw wag na ako magcoolant?

1. Unless your car is aircooled like old school VW's or Porsches, you will need coolant to increase the boiling point and have a higher margin of safety.
2. Find a new mechanic.
3. He probably said that so your car will not last as long and you will take it to him.

That's why these forums exist so people will know better and not just rely blindly on others' advice, mechanic man or hindi. Mechanic ba talaga (with certification, license, etc) or no real way to authenticate him?

Thanks for the reply. Nagsisimula pa lang ako matuto pag dating sa car.

Matino naman yung mechanico. Sya yung nagpalit ng timing belt ko a year ago. Marami din nagpapagawa dun sa talyer and ang laki ng talyer.

Never pa ako gumamit ng coolant sa car ko. Puro tubig talaga. Never pa napalitan yung Water Pump.(hindi ko sinabay sa pag palit ng timing belt kasi gusto makita kung aabot pa sa sunod na timing belt change.)

Mga 89,000 kms na natakbo na car sa 10 years. Honda Civic VTI

Pero tataka ako dun sa Lancer GLXI 97 namin na naka-coolant. Mas mababa pa kms kaysa car ko pero palit water pump na agad nung dumating sa 50,000kms.

Bakit ganun yun nangyari?

statistically, you can't compare the two because they are different. also civic is more reliable than mitsubishi, more robust..

water has greater heat-trasfer capability but lower boiling point than coolant..

Ok.

In laymans term?

Thanks

use coolant for its anti rust properties. not for the cooler engine temps.

open up the civic and the lancer and i'm pretty sure which one will have cleaner water passages.

water: heat transfer capability means more heat can be absorbed by the water away from the engine but water has a less boiling point (100 deg C) compared to coolant. so if na-reach na ng tubig ung boiling point nya especially in hot and long driving, there's a lot of steam generation trying to escape out of the radiator (overheat)..

coolant naman, although less ang heat transfer capability nya, they have high boiling point naman (130 deg C). may anti-rust and lubricating property pa..

Peeps singit lang na OT.

Pwede ba halo ang coolant additive sa water methanol injection? Antirust?
Totoo ba pwede wiper washer fluid dito? Is it economical?
Where in Manila can people buy methanol in bulk for this application?

+1

The Lancer's water pump failure could be due to any number of things not related to the use or non-use of coolant.

I'm really pissed with one of our former drivers... he made it a habit of topping off the Crosswind with tap water. Now we have a problem!

After 10,000 kms of use with tap water, the coolant bottle is full of rust and the radiator looks like it's full of mud... and it's losing water every few hundred kilometers... I'm thinking quite a few of the internal water passages are clogged by now.

-----

While you can run a car for quite a long while on water only, it's a huge compromise. The Civic might be able to get away with it, due to its well designed water passages and an engine that doesn't need as much cooling as other 1.6s and which can survive overheating better than most... (I'm still amazed by the tiny radiator in that thing) ...but it's not going to be a very happy engine by the time you need to overhaul it.

ask lang po mga bro, may evrerest 2007 model ako ,ang coolant niya ay kulay green ngayon ang nirekomenda ng ford dealer ay Shell Coolguard OAT na kulay pula,pwede ko ba e halo o ilagay sa reservoir ng radiator? maraming salamat po!
