I see all these signs around were i live saying something like "coolant flush 49.95". What is the point of a coolant flush?

thanks

Re: coolant flush

It cleans out your old coolant and any garbage that has formed in there (i.e. sludge from dexcool).

Re: coolant flush

If you don't change it at least once every 4 or 5 months, it can really get down right nasty looking (depending on how often you drive your car). I'm not sure what the recommended specification for flushing your coolant is offhand, it's probably something like once a year. But, from what I have witnessed with my own coolant and others, I would definately change it more often then that.

Re: coolant flush

I flush once a year and it doesn't look to bad, but I do not use dexcool.

Re: coolant flush

dexcool should last longer than 5 months unless you have a problem. the reason for the flush is because of thrash and gunk that builds up. really does help especially since you will getting new coolant in there

Re: coolant flush

i read in my manual that dexcool lasts 100,000miles before it needs to be flushed...i thought that was odd

Dexcool may keep it from freezing for a 100,000 miles, but a lot of slug will build up.

Re: coolant flush

I've got dexcool with about 88k miles and its looking pretty nasty. I think it says like 5 years/100k miles for a flush.

Re: coolant flush

Well, I have the problem of both worlds. Somewhere along the line of my car's history someone decided to put regular (green) coolant in my radiator with the Dexcool. That gave me enough problems, and just when I thought I had the gunk somewhat under control, the car sat for over 2 years and just gunked up the entire time making that rust looking color everywhere.

I have to fix this asap.
