Radiator/Coolant flush/replacement

Apr 11, 2007 14 Replies

How many years/miles should this be done? My 2002 wrangler has 68,000 miles on it. Not sure if previous owner did it - he did follow the service milestones to the T however.



Make sure to get the right stuff, and replace all the hoses at the same time. If you do that you should get another 68,000 out of it. People will tell you stuff like 2 years, 30,000 miles, but that is way overkill in my opinion and a waste of natural resources besides.

2 years for Green, 4 years for G-05

Zerex brand only

So you'd rather replace the coolant with the radiator, pump, plugs, head gasket? ;-) God Bless America, Bill 0|||||||0 mailto: snipped-for-privacy@aol.com

I've had Green in cars for ten years or more, if it's the same formulation. Maybe these new engines made of pot metal are different, but I don't think so as long as you use the right coolant or mix and distilled water. I think this answers Bill's question too.

Except I stick with the two years, and get eight years out of the radiator (corrodes from the outside in, via sea air) and water pump. No core plugs in fifty years, thirty years, twenty eight years. With the green stuff, that I'm sure the formula has changed many times, you will see you have to dig the block drains plugs open each time. And out comes a black stuff that's got to be an acid, as it eats the plug a clean silver. God Bless America, Bill 0|||||||0 mailto: snipped-for-privacy@aol.com

formulation.

There's no paint you can use? A radiator lasts forever in Colorado.

I got my ear pinned back once when I was caught spray painting a radiator. I was explained to me that paint, even a thin layer held the heat in. And in the old days my Fords ran on the razors' edge, anyway. God Bless America, Bill 0|||||||0 mailto: snipped-for-privacy@aol.com

The new green claims 5 years, I wouldn't trust it past 4 years but maybe that is just me.

The new engines are full of new metals though, perhaps that is the problem.

There are more than one, incompatible formulas now, and the price of coolant has gone through the roof too. That doesn't help much. If your car boils over in the Arizona desert, because of neglected hoses, there's just no telling what the nearest repair shoppe is going to have in stock.

I'm using the G-05 now. I like the cool clear color. I put Honda Genuine Coolant (blue) in the Hondas, and Walmart diabetic monkey piss in the Suburban.

Hi Earle, Fueling thousands of cars from Mexico, urine is often the smell from their radiators. Their untested drivers and uninspected commercial trucks are about to enter your state. That should eliminate a few of your sports cars, whom thought trucks had brakes, cause now they actually won't. God Bless America, Bill 0|||||||0 mailto: snipped-for-privacy@aol.com

Nuevo México is a pretty big buffer. I am in Albuquerque right now, but I spend most of my time in Colorado. These folks are a lot closer to your state.

Have you seen the road I live on?

Earle

Many, of my classmates moved to Albuquerque, and changed, never making any of my reunions. Many of the Indians there have a strange idea of who's land it is. Visions of Jack Nicholson in the Shining come to mind, thinking of your home. God Bless America, Bill 0|||||||0 mailto: snipped-for-privacy@aol.com

Maybe they just don't like you, never did, and don't want to be reminded of the bad old days.

And that strange idea is......?????
