coolant flush...step by step with pics

[djomlas]

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.

mine was fine too from 98 till few months ago. they tend to let go and then ull have some problems....it cost me17 bux, so while ure at it i would suggest changing it so youre clear from that standpoint

Good writeup! I may have to do this within the year. I've knocked out a lot of the periodic maintenance stuff, but have a few more items I could cross off of the list.

when i saw the forecast i told myself i had to do it, its been cold as hell all week, and that day it was 44 or something like that, and now a day later its 13 and snow

btw, posted the picture of actual zerex bottle

dj,

How did you ensure that you got all the old coolant out of the system? Since the radiators are all the way at the front of the car and you had the rear end on ramps, it seems to me that there would still be old coolant in the system. In the past, I've disconnected a heater hose and fed the system with a garden hose while the motor was running to flush everything out but it looks like you didn't do that.

Probably not a huge deal - I was just wondering if you left out a step or if you really did just drain and refill.

I would also add - make sure the car is warmed up fully when you drain the coolant. When you refill, make sure the heater is set to full hot. If the heater valve is not open, you won't get out any air trapped in the heater core.

Thanks for the writeup.
