How to flush rust from my car cooling system?

[Chinoi]

Just found out that my thermostat was damaged by rust. Ano procedure para ma flush out ko yun mga rust bago lagyan mix water and coolant. Dati kasi tap water lang gamit ko.

Picture of replacement thermostat and damaged one.

try muriatic acid, babad mo..then scrub rub...ingat lang sa paggamit ng muriatic a, use proper hand gloves..

i do not think i would like to re-use that damaged thermostat anymore, even if i cleaned it.
as to flush out rust, i think it's just a matter of opening the drain plug at the base of the radiator and wait for all the water to drain out. some say it would be better while the engine is still hot.. daw.. then, you close the drain hole and pour in your choice of coolant.

Have your car's cooling system undergo L'avramon...

Kagagawa lang ng car ko.. sabi sa akin ng radiator expert... dito sa pinas di mo naman kailangan yan... valve lang yan.. gamit yan sa heater ng sasakyan which is di naman natin ginagamit... Tangalin mo lang yan at wag na ibalik..

Una, dapat palinis mo muna sa mga naglilinis ng radiator. Tinutusok yang radiator para matangal yung tumitigas na kalawang. Para naman mas matangal pa ang kalawang, gagamit ka ng coolant with anti-rust .. tapos wilkens water ang gamitin mo... after 1 week.. palitan mo uli ang tubig... lilinis na yang tubig sa radiator mo.

Hindi radiator expert yun sir,
Yes, valve sya, it opens up when it reaches the operating temperature ng auto,
Kapag wala yan, you will burn more gas kasi mas nageeffort ang engine maabot yung operating temp.

Nandyan yan for a reason,
Kaya nga nilagay ng mga car designers and engineer yan, kasi may purpose, kahit nasa pinas ka, alam nila yun.

Wag basta basta maniniwala sa mga dyan dyan sa tabi radiator shops,
Research ka lang sir, you know better.

Saan shop meron may L'avramon and how much ang labor charge?

Hinahanap ko nga kung paano improve fc ng engine ko. Nakita ko yun white thermal valve na barado. May 2 vacuum hose naka connect dito sa thermal valve . From carburator and to the distibutor vacuum advancer. According sa manual ay dapat open ang thermal valve at mag close when 80° C was reached. To be able to replace the white thermal valve. I need also to remove thermostat. Kasi magkatabi ito 2 valve. Dun ko na-discover na wasak na pala thermostat ko.

So pwede rin yun sinabi mo na cause ito ng hindi efficient ang fuel consumption ng Lancer 1.3 engine ko during cold start.

Sir, hilander ride po. Already had the radiator overhauled. Tapos nilagyan na ng coolant mixed with water coming from a softener water system. Pero after a while, naging kalawang color ulit ang tubig. Di kaya ang kalawang nanggagaling sa makina kung saan umiikot ang tubig to/from the radiator?

Its possible that some rust are in the water pipings and water jackets....

Ito ang reason kaya ko gusto ko malaman alin safe pang remove ng rust sa internals ng cooling system or piping. I'm considering rust remover na ilagay sa radiator. Ang worry ko lang ay luma na yun radiator ko. Baka magkaroon ng leak pag sumobra ang rust remover. Ano kaya magandang brand?

Rust particles as long as they are suspended in the coolant solution is tolerable unless its sludge. It is when they deposit themselves on surfaces that problems begin to precipitate.

If to borrow a term from OTEP, "rodding", is not recommended for radiators of light vehicles.

I wouldn't be so quick with using muriatic acid, its normally used as a treatment for cleaning stains and oxidation but it will also dissolve metals given the right conditions.

But there are engine flushes that are more alkaline based that are safer to use, just make sure you rinse your loop before you refill it with coolants.

If the mechanical components of your thermostats are broken, you wouldn't want to reuse them. Those are stamped sheet metal parts not exactly the best for rework under those conditions.

The active component of common thermostats is a wax-based compound that is formulated to expand or contract in a given temperature range.

Your car would run without a thermostat, it just wont' do so optimally. Besides its costlier to repair again unless you personally enjoy tinkering with your ride.

ganyan din yung dati kong Hilander.. ang ginawa ko is I use purified water from water station and replace my water weekly.. sa radiator lang via drain plug.. then after few weeks nagiging clear na yung water.. tapos that's the time na gumamit na ako ng pre mix toyota coolant...

You would have achieved similar results by just doing a proper flush once. Exposing your engine components and radiator to plain water for an extended period, purified or not, causes problems with metal surfaces.

So what is the best water?

sir EVO-V, para naman sa ikabubuti ng radiator ni TS, ano nalang ang ginagamit mo sa auto mo?
yun nalang gayahin nya para perfect na cooling system nya.

ok naman result... our Hilander is still alive and kicking with original stock radiator since 1997...

TS the best talaga is lav ramon..

If its just for flushing purposes you may use clean tap water. Its going to be drained anyway.

Drain old coolant into a pan or container. Do not wantonly discard this as it is toxic and harmful to the environment.

Then use radiator flush, run for 15-30 minutes, then replace with plain water, then run for 15-30 mins again, then drain. Repeat this until you're satisfied with the clarity of the water in your system, then drain and replace with your preferred coolant mix in and be on your merry way.

Newer cars with aluminum blocks and rads are more sensitive to water only application. So be mindful what you put in.

There is no mystique to this. Just commonsense science and diligence.
