Tubig sa reservoir kumukulo...help! temp gauge ok pa rin...

sabi ng mga nagre-repair ng radiators, dahil meron na raw kalawang, mas delikado raw gumamit ng coolant dahil magbabara pag nag peel yung kalawang. suggestion nila distilled water. tama ba sila?

If water was never used during the vehicle's life then I don't think you'll have the kalawang problem in the first place. Coolants also prevent rust and scaling. Water means more income for the radiator repair guys ;) There are radiator flushing solutions that can be used to flush out the rust. They're good for just a few kilometers though.


When the engine overheats and the rad cap cannot vent enough pressure the plastic radiator ends will blow first. Replacing the plastic with tanso will make the rad stronger but guess what will blow when the engine overheats again? The head gasket

There are no plastic headers, you must be referring to the tanks.

Those plastic tanks are made of fiberglass reinforced polyethylene. They are for cost reduction. Purely cost reduction. All they need to do is outlast the car's warranty.

Headers, tanks, IMHO its the same. We are referring to the things crimped on both ends/sides of a radiator core. Thank you for enlightening us that it is just for "cost reduction" purposes.

Re: distilled water, yes I suggest you use that, and the proper mixture/ratio of coolant if you want. I use distilled water in all my cars, no problems whatsoever.

Much obliged, Sir.

Distilled or otherwise doesn't matter. Clean and filtered is all you need. Once a hypotonic solution comes into contact with any and all metal parts it becomes contaminated and will dissolve anything it can anyway.

I suggest mixing your coolant/water outside the radiator before pouring it into your loop this minimizes your water from dissolving anything else.

only if your engine and radiator are made of glass.
alas, our engines and radiators are metal alloys. they corrode over time and heat. the corrosion product is the dumi or kalawang that they refer to.
it is the duty of the coolant additives to slow down or prevent metal corrosion..
will these coolant chemicals solidify these kalawangs into more solid pieces? i don't know..
you know, we never had this problem in our cars for the 20 or so years we had them (air-cooled volkswagens.. heh heh..)

You have a leak.

Radiator systems are sealed systems for good reason. Air inside the loop makes for poor conductivity and they really don't need to be maintained.

If by the time your water only coolant evaporates -it already means that your cooling system is in trouble.

Your radiator is designed to keep your engine operating within 80-90C. Water boiling inside your cooling loop at practically 2 atmospheres means your engine is overheating. (the pressure cap elevates everything by 1 atm)

Having coolant only raises the boiling point of water but lowers its thermal conductivity.

If your engine has severe cavitation you will likely have leaks through it in which the coolant seeps through.

sir normal lang po ba kung 80-90C ang temp pag longdrive ?
pure water lang po nakalagay sa radiator

Yes as we are always reminded in chemistry class "water is the universal solvent".

Atleast I was always reminded as "I failed it not once but twice."

[EVO-V]

^lol double reminders then. :D

But people, you have to stop trusting the science that the corner "RADIATOR COVERTION", "OVERHOLE" establishments provide. There is no science!

If you remove the coolant you will have more rust. The fact that it will clog more is because they really never cleaned it properly.

Scaling will attract more scaling. Once your solution (coolant) is saturated, it will begin depositing more particles on the encrusted surfaces causing more clogging.

Sus ginoo!

Cruising should afford you a lower normal temp somewhere around 75-80C. Under load 80-90 is optimal. Again this depends on engine design. Some engines are more thermally efficient than others.

Wew! dami na pala answers dito.. salamat mga sirs..

HAd the radiator cleaned last weekend. tested it for a long drive. kumukulo pa rin (pero take note di pa rin tumataas ..kalahati pa rin ng gauge)
Again, the engine runs great and I dont see any pagbabago sa hatak, maayos pa rim, kahit tirik ang araw..

What test na pwede ko magawa para malaman ano sakit? water pump kaya....?
help again sir... thanks alot,,,

Have your cooling system pressure tested. Chances are, you have a cylinder head gasket leak. See my previous post somewhere here.
