coolant flush...step by step with pics

[djomlas]

this is the Zerex used

then after its all out, close it and top off with coolant/distilled water mix to MAX

turn the car on, and let the engine get to the operating temerature, and every minute or so rev it up to about 4200RPM, this will take about 10 minutes or so.
shut engine off, let cool off, then top off to MAX again, put the bleeder valve down, replace the plastic cover, tighten both caps on.
some people like to drive w bleeder valve open for a day or 2, this will not hurt the car

Just a couple of questions as I'm gonna do the coolant system flush soon. In the Bentley manual it says the car has a coolant holding capacity of 4.5 gallons,now that's 100% coolant right? Now as I let the car idle and the coolant needs to be filled the mixture that you put in at that time should be 50/50 coolant/distilled right?

Is this the right coolant?

well depending on the temperature, on the bottle it said if you will have your car in up to -34 degree temeratures mix 50/50 coolant and distilled water, which is what i did.
if you will be in even colder cinditions it will show different mixture conbinations.

so you need certain capacity, now whichever way yo want to mix up your coolant/distilled water mixture is up to you, or better said the conditions you live in.

hope this helps

Hi,

A couple of things. Water is the best heat conductor available, so the more water you have the better for this purpose alone.

But, the Coolant also provides corrosion and lubrication protection, so you need a certain amount of this in the mix as well. 50/50 (distilled water/Coolant) works fine, but 60/40 is better for heat management while still providing adequate corrosion and lubrication protection.

So, check the Coolant and use the smallest concentration of Coolant to distilled water your area's avg. temps call for. Hope this helps...

Well, my cap ends in 00. How important is it for me to buy a new one as soon as possible? I mean... Its been good for 8 years, and the old saying " If it aint broke, dont fix it" comes to mind.
