hey guys; jst wanna check & ask a few question about coolant & correct method in filling up the coolant in the radiator.

a) wat type of coolant are u guys using?
b) do u mix water to your coolant?
c) wat brand is recommended?

the pic below shows 2 type of coolant; toyota n honda.
n both stated, 50/50 prediluted (DO NOT ADD WATER)
does it mean i gotta buy 2 bottles of the coolant n pour right into the radiator without filling up water at all?? will the coolant be too thick?


i'm from malaysia; doesnt snow here. it can get really really HOT.
want some heads up from pros around here :p
 
i am using the honda coolant i bought it in a 4L package and i fill the car only with the coolant no water at all.that is the way honda recomends its not thick like other companies coolants which need to add water.
 
ehhm.. tats wat i thought so too.. since its stated on the description there do not add water. but wats ur country temperature like?

malaysia is HOT n i dunno; mebbe they are afraid tat the coolant can be took thick for this country's temp??

n the funny thing is; i jst call up one of the honda malaysia service center; they also say get a bottle of coolant, pour it in the radiator n mix water .

very confusing.. need more heads up..

thanks.

Alot of the toyota engines have steel blocks and the stuff they supply is made to protect that metal. when its pre-diluted you have to buy a couple of tubs and put it straight in without water.

The antifreeze/coolant has better thermal-conductivity than water alone... i.e. it'll absorb heat faster than water alone... hence using proper coolant will allow the engine to cool itself more efficiently. :nice:

a) Honda type-1
b) No
c) Honda OEM type-1 or type-2

Type 2 just has longer life than type-1. I use type 1 myself. Just because at 50,000 miles mile current engine will be due a basic rebuild (piston rings) so with the extra cost of type-2 over here, I just use the cheaper.

And the coolant wont be too thick. :nice:


If you struggle with temperatures and your car runs a touch too hot... you can use coolant additives like one made by REDLINE lubricants for example... they make somthing called 'Water-Wetter', it breaks down the surface-tension in your coolant and makes it conduct heat even better. ...of course the real solution would be a suitable sized radiator if you do have an aftermarket setup. :nice: ... EDIT :but if you have stock or near stock setup and your overheating then you have a problem you need to diagnose and fix!

Filling Instructions:

*Park on level surface
*turn heater temp control to maximum hot
*Crack the bleed nipple open thats on the top outlet pipe of the radiator (if it has this)
*fill the radiator to the baes of the filler neck, (itll keep draining back down the top-pipe into the block, keep pouring a little extra in at a time until the level stays the same pretty much full)
*then close the air bleed nipple,
*replace rad cap.
*remove, empty, cleanout and refill the expansion tank to the MAX line with pre-mixed anti freeze.
*start car and allow to run untill the fan comes on and goes off twice (from being cold this is - never pour cold coolant into a hot engine!)
*then shut off and allow to cool down until its safe to open the cap....only open the rad cap (not bleed nipple), top it up if needed
*put lid back on and bring car back to temperature.
*CHECK FOR LEAKS.

Thats all you need to do to get it perfect every time. :nice:
Honda used to supply colant that had to be mixed with water but nowadays its all pre-mix. nice and easy.

Hope that helps :)

Dont worry about what the honda guys tellig you (mix water with coolant)....

when the coolant says DONT, then DONT.. the honda dealer guys you spoke to probly looking thorugh old manuals.... the Honda brand fluid might seem a touch thick but it'll thin out with heat from the engine.

Seriously my first post to you is everything you need to know/do with this. :nice:
 
thanks ek9 turbo :)

hehe; fyi ; i m not having overheating issue at all; i m using a double layer fully aluminium radiator;

i m asking becus; my old coolant i have flush it out since i had to clean my engine head plus i replace my stock hose to silicon hoses.

so i have to refill the coolant. currently running in jst water only.

BTW. another thing is.. u know our ek spare radiator tank? the plastic ones right??

it has a minimum n maximum level to it.

the thing which i m confused now is.. @ COLD , no engine start up.
is the water level SUPPOSE to be @ MIN lvl or MAX lvl?

cos it gives me the impression where by its like the brake fuel u konw? when its at minimum; top up to max...

BUT i've been googling around. it seems there's some article stating that @ cold; the level should be @ min level; n when the engine is really hot; it will reach the MAX level.

n NOT MAX level when its cold.

is that true??
 
incorrect. It should be at MAX level when cold... thne it still has adequate room for fluidexpansion.

What happens is when you turn your car off and its hot, heat is 'soaked' i.e. conducted from the block into the coolant.. this makes the coolant try to expand because its not being pumped to the radiator to get rid of this heat... so the fluid expands slightly and this tank is there for that purpose. the additional coolant is there so that if there is any air in the system, as it works its way out to the top of radiator/expansion tank theres extra coolant there to take its place. Fill expansion tank to MAX

tq ek9turbo :)

gonna tighten the clips more; currently with the new hoses; n jst running on water;
everyday i check the spare tank water; it seems to get lower n lower

so i m guessing the clip isnt tight enough n have minor leaks; but everyday early morning i peek undercarriage on the floor no water drip :p

gonna check out tomorrow.

thanks guys./
 
btw. coolant boils at higher temperature than water.

fill with honda coolant type-2 ideally, then watch the levels. also double check your drain plug on rad and check oil-cooler colant pipes for leaks. It will go down a touch at first as you get the air out of the system but should settle after a day max.

put coolant into it! :nice:
 
oh yea.. from ur above post right; u mention to turn the heat temp MAX.

tats b4 i put the coolant right? i mean i drain out all the water first.. den.. i turn it the temp to MAX, den fill it up with coolant, turn the key n let the aircond, run right??

BUT don start engine first.. fill n fill n fill till max tip top..

close the cap; start engine n wait awhile till the fan goes on..

n so.. follow by wat u mention after that..

correcto?? :)

got a strong feeling its the clip there not tight enough; cos i m not using those screwed ring types.

jst using the ones u press against with a side to expand only.
 
AC is not relevant. but if you just mean the heater controls then yes. the temperature lever or knob must be at max. the interior-blower/fan doesnt need to be on.

so ...before you put coolant in you turn heater control to max as it has a little valve in the pipe to control the ammount of coolant that passes into the heater-matrix in the cabin.

if this was on low temp when you drained/filled then you may have air in this... and as the coolant/water works its way in it will make the level go down.

When you fan is on and your engine is hot/running, youll see any leaks from the pipes... and it will smell of coolant.


This may eb why your levels going down. Refill with coolant. :nice:

Yes but water transfers heat better than coolant.

So in effect, the more water you run, the cooler the car will run too.

Honda-Tech.com: Road Racing/Autocross: Question about coolant/water mix ratio.

Since you are in Malaysia, I would run an 80/20 or 70/30 mix. I do that on my track cars and they've never overheated and the only time they did was on the way back from the track stuck in traffic, since I also did not find the time (nor the wisdom) to install a radiator fan.

Use the coolant mainly for corrosion protection and lubrication, NOT to raise the boiling point. The pressure in the system along with the majority of the water will keep heat transfer in check.
 
ohh.. could be so..

mine doesnt have the air release nipple.

old skool radiator hehe..

well thanks alot den.. gonna try it out :)

OH no.. here goes the mix mix.. :swt:

hey guys; are u using after market radiator?? iF SO. how much coolant is needed?how many liters?

MF: Whilst it is true water is a much better conductor of heat.. you shouldnt NEED to add water to the mixture if the cooling system is adequate.

The bleed nipples are on the top pipe union of the radiator outlet from the head. No on radiator. :secret:

there's one? i dont recall seeing;
well if u ehh.. going to ur car; snap a pic for me :p

i'll do a report tomorrow IF i m getting it done tomorrow :)
 
Well I use texaco truck coolant on my b18c lol, works fine for me!
