How to flush the radiator

[choycontreras]

Paano nga ba ito ginagawa? How do they do it in the casa or those MIDAS shops?
DIY yata ang gusto ko dahil madali lang naman yata.

Flushing the radiator is easy, DIY lang:

1. Remove the radiator drain plug (usually nasa bottom part ng radiator) then let the water flow.
2. Remove also the water/coolant on the reserve tank as this may also contain dirt accumulated over the years.
3. Put back the drain plug and add a radiator flush like Whiz or Snap. Then fill the radiator with clean water.
4. Run the engine for about 10-15 minutes (gusto mo patakbuhin mo muna yun car mo around your village :lol.
5.Let the engine cool down then drain the water in the radiator (siguro mga 2 hours medyo malamig na yan car mo).
6. Check for leaks in the radiator hoses and check also if the radiator cap is still ok
7. Then add distilled water and coolant (minimum 50/50). Put pure coolant to the reserve tank (don't overfill, may indicator naman yun, around half of the tank ok na).

yan ang ginagawa ko every 2 years kaya 10 yrs na radiator ko ok pa rin, radiator cap and some hoses pa lang napapalitan :D HTH

pdc2,

Thanks for the nice and clear instructions. It sure will save me some 500 bucks sa service from those big shops.

Pagbarado or suspekted barado, you can remove the whole radiator and do a back flush. Meaning entry ng water sa bottom hose hole and out sa top hose hole. Binabaligtad ang radiator that is why you need to remove it.

pano po sinusukat yang 50/50 mixture na yan? yung PEAK pwede d ba?

meron ding binebenta sa caltex yung extended life coolant. it's a relatively small bottle good for 1 radiator na yata. ok ba yun?

[choycontreras]

Good!!

Had my car and van done by myself this morning. Madali lang naman pala.
One of the radiator flush's instructions was to have a very slow water hose put on the radiator top while the engine's running so that you can see when the remaining coolant will drain out until it turns colorless. Dont put on a high pressure hose or else baka ma-'pasma' si kotse mo.

Also, I used mineral water (soft water) instead of distilled water - scaling lang naman yata ang concern so I guess pwede na ito.

[pdc2]

choy,

nabasa ko before here sa board na mineral water contains minerals that could harm your radiator...that's why the best pa rin ang distilled...ako i used SM Bonus or absolute distilled water, cheap lang naman sya.

icon, saw that PEAK coolant sa PriceSmart. Will try it nga next time :lol: Para sure ka, yun pre-mix na lang bilhin mo, no need to add water.

choy, using mineral water will promote scaling and rust. you should've used distilled water, the point in using this is wala siyang minerals. advice lang pare, drain mo ulit yung cooling system mo, then use distilled water asap. in a few months time, magbabara ang cooling system mo, believe me. huwag ka manghinayang kung bibili ka ulit ng coolant.

another way of flushing is thru descaling, it also effectively cleans the engine block. but its a little bit expensive (1k++)

Point of argument:

Mineral water does contain minerals but it is without the scale-causing Calcium and Magnesium ions (which when combined with metals, form oxides or salts). Mineral water processed in the shops pass thru the - water 'softening' stage. Have majored in Chemistry so I believe this is how it goes.

Practical explanation - you dont see scaling in your 'mineral' water containers, do you?
Tap water used in containers do have a lot of these scale causing minerals, thus creating chalky residue on top.

Correct. But common sense should have dictated that distilled water is still the best way to go. Soft water may still contain small amounts of Ca and Mg and may not entirely be eliminated (hence, the term "mineral water" : meaning, it still contains minerals). I don't see the point of putting mineral water in you radiator when distilled water basically costs the same and is readilly available..gets???

Dun sa casa, tinanggal talaga yung radiator ng kotse ko, pero gumamit muna ng 'in-house' radiator flush bago tinanggal.

While the radiator was being reverse-flushed, yung engine pina-andar with a supply of running (tap) water through a hose.

Lahat ng cooling system hose and reservoir was flushed.

Tapos, balik na, and the 50/50 glycol/distilled water was put in, and it was good for the next five years.

of you can just have a lavramon type service done para simpler.

Your arguement is good only in paper. However, you won't distincly see scaling in clear plastic bottles since it won't stick to plastic due to absence of ionic charge. While metals do have a charge. Only way to verify their presence/absence is to boil the water. If there is no chalky residue at bottom of vessel after you pour out the hot water, then there's no Ca/ Mg.

Chaulky residue on containers of tap might be other impurities, since Ca/Mg do not have exclusive affinity to surface tension. And if it does, they won't be visible in bottles since they are filled to the rims.

Distillation burns off all remaining Ca/Mg

You might have a major in Chemistry but I'm a genius

sorry, for a stupid question. pero pano po ba idedrain yung sa reserve tank? wala namang drain plug yun?

You can pull out the tank check where it is connected to the body of the car it just slips off

hehe!pre tapon mo lang sa bunganga ng reserve tank, liit lang naman nyan..:old:

[ninjababez]

Mga bros, nag flush ako radiator
ok ba yun condition nung water?
Yun white debris, galing sa basin mismo.
Lagyan ko muna distilled water, pwede ko na ba lagyan long life coolant after?

Thanks
