Need help regarding radiator draining and refilling of coolant

[eajrapogi]

Hello po... just want to ask if need pa po ba idala sa talyer ang sasakyan pagmagddrain ng radiator o pwede kahit ako lang po.. and if ever pwede kahit ako lang, can i ask for guidelines and procedures, also what type of coolant should be used.

Toyota Hilux Surf 91 model po yung gamit ko...

Maraming salamat po.

You can do that on your own.

Make sure the engine has been off for a few hours so as to avoid dealing with 2nd degree burns.

1. Get a 3-4 liter container and put it under your radiator drain.
2. Unscrew (its a plastic wingnut) the plug which is normally situated on the lower tank of the radiator.
3. Drain.
4. Tighten the plug.

Make sure you dispose of the liquid in a proper sewer drain not on the ground.

Now before you fill up your system again.
1. Get a radiator flush and fill it in
2. Add water.
3. Run your engine, intermittently revving to circulate and turbulate the detergent. Idling for about 15-30 minutes as necessary depending on the residue from the initial flush.
4. Drain the engine as per the procedure above.

Rinse and repeat as necessary so you can get as much corrosion out as possible.

Personally I would put a mesh during flushing on the radiator inlet to catch any loose debris.

Fill up your cooling loop with 30% coolant and the rest with clean preferably filtered water.

I recommend blowing air through your radiator core to dislodge dust and debris.

Wouldn't hurt to shampoo to degrease it and rinse with low pressure hose your thumb on the hose should work fine. Dry with pressurized air or just let it dry on its own.

Sir Evo-V, thank you for the guidelines you gave...

[EVO-V]

You're welcome.

Likewise, its important to note that given the age of our engine it may not just be the radiator you need to flush clean but your engine as well, especially if its been running with no coolant for a long time.

Be weary of those "radiator overhaul" places most of them don't understand the science of radiator construction.

Mura nga pero masmahal ang magpa-overhaul ng makina.

I'm just a newbie, unable to post new thread sorry for hi jacking this thread my apology ..

Naka bili ako ng second hand Honda idsi 2004 a 13yr old car w/ 81k kl. reading odometer

previous owner used water on its cooling system never mention if its distilled or tap water( ayaw na kasing mag reply inquiry ko. I do have plans of draining it or perform flashing(flashing solution) procedures, but I'm a bit worried about all the dirt residue will come out that will have a possibility to trap on its way out.

Please advice me what to do...
1. just drain the old cooling liquid then replaced w/ distilled water
2. perform flashing procedure (flashing solution) then replaced with distilled water + coolant solution 50/50.

please help me decide

First, its toilet "flush". hindi "flash"light.

There are lots of videos how to flush your radiator.

Once you drain the old coolant, you'll see naman if there are debris. Normally minimal if the car isn't too old.

Why are you scared to flush? Its just like mumog? the more the better...

Always use coolant mix not just water.

I think best advise po no. 2 pero mas ok po kung pure coolant po ang gagamitin.

same lang kahit may heater, make sure to turn the heater on while flushing para masama sya sa malilinisan

Update lang po sa BB ko. Nag pa overhaul na po ako. Nung binuksan ung rad ko, dami po palang parang brown substance na malalambot na namuo na sa pinaka cover ng rad pati dun sa maliit na butas. Talagang linisin na po pala rad ko luckily hindi pa raw po pumuputok yung pinaka cover plastic lang po pala un? Paano po un nagiging copper? Anyway. After malinis, nirecommend na alisin na rin po yung thermostat ko, para maganda raw po tuloy tuloy ang circulation. Ano po say nyo? Pinatanggal ko naman po. Tsaka yung sa may hose po sa baba ung mga namuo na oil, sabi nya dahil daw po un sa ATF. Bumili lang po ng ibang panghigpit para di na ulit mag leak. Ayun po just sharing lang. Wala po kasi akong mapag kwentuhan about sa car puro kasi kami babae sa amin haha salamat po.

ibalik ang thermostat.
it helps lessen pollution, and helps save a little fuel.

vios sir?

oo, yan yung drain para sa radiator.

yung sa coolant reservoir, nahihiwalay yun sa radiator fan cowl. parang snap on siya, buo siya natatanggal. wag mo bubunutin yung hose sa baba ng coolant reservoir paakyat sa radiator cap, mahirap ibalik kapag hindi naka baklas fan cowl. pero kung kasya braso mo, baka mas madali, hehehe

Yes Vios 1.5

Ano yung fan cowl? Sorry d ako sanay pa sa terms na yan [emoji1]
Pwede ba yung sa taas na part na hose ang bunutin ko? Para mag drain ang rserve?

Yung drain ba ng radiator kapag nabuksan sya yung plastic na yon, iniikot lang ba yon tapos mag ddrain na sya ng tubig? Tnx

old school term yung cowl, mas common ata radiator fan shroud.

yung sa reserve, pwede tanggalin yung connection ng hose papuntang radiator cap, tapos siphon na lang. pwede gumamit ng malaking syringe.

yung sa radiator naman, kapag natanggal na yung drain plug, iniikot lang siya, mag drain na yung laman ng radiator, dahan dahan lang yung sa radiator drain plug, hindi ko kasi matandaan kung may gasket or o-ring yung drain plug, kapag nawala, pwedeng mag leak. double check na lang sir.
