coolant question

Hey guys, got a quick question about doing a coolant flush. I bought my car about a month ago and it hasn't had the LIM replaced yet. The oil looks good and I don't see coolant leaking anywhere, so I plan to replace that myself (as well as new valve cover gaskets, new tstat, supercharger gasket, supercharger oil change etc) in the spring. I would do it sooner but I really don't want to do it until its warmer.

However the coolant itself looks quite old and dirty (somewhere between orange and brown in color if I had to guess), but I don't see any evidence of the "oatmeal" texture sludge that I've read about, at least from popping open the radiator cap. My question is should I have the coolant flushed right away, or can I just wait for spring when I do the LIM gaskets?
 


how to flush the coolant.


remove the t stat, put the t stat housing back on, take the upper hose off the radiator, then push it down to the ground to a bucket or let it fly.


get your garden hose out, put it in the rad turn it on, then fire up the car, let it run till clear water pumps out the top hose.


then turn the hose off, run the car till no more water comes out the upper hose. then turn it off.


put your t stat back in, with new gasket, the upper hose back on.


now take 1 gallon of full strength green antifreeze, not the 50/50 crap. ( parts store cheap green is fine to use) dump the whole gallon in the radiator, fire up the car, fill the rad with hose water till its full. top as needed till its ready to be bled of air. it will burp and take coolant as the water in the block warms up the t stat opens up for a few seconds till cold coolant hits it and it shuts again.


now to bleed the air out, let it idle rad cap off till the fans turn on, (when the fans are on the temp is over 195 deg, the t stat is wide open) then open the bleeder screw on top the t stat housing a few turns till a steady stream of coolant comes out the hole, shut the screw, top off the rad. cap it.


done.
 
It really is a simple process for what it's worth. I'd personally do it myself if I was in your situation. Old coolant can allow coolant passages to rust and can help wear out your water pump. Just byte concentrate and dilute it yourself,and it should be pretty cheap.
 
I'm not really looking for a how to, I'm just asking if it should be done asap or not because it looks pretty crappy.

If I were to do it right away I would have someone do it for me, just because snow, no heated garage, no hose this time of year..
 
i used my hose year round when i had a house. after your done un hook it and drain it, then roll it up and store it again.

if you turn your water off, turn it back on, then back off when done. most of the time this takes nothing to do.


no way id pay 50 or more to have it done when it can be done for 15 bucks or less most of the time at home.
