I had my 850 wagon in the shop a while back for brakes, and the mechanic said I had the wrong coolant in the car. He says it should be blue not green. Is there somewhere I can buy the blue coolant beside the dealer? I live almost 300 miles from the closest dealer.

 

I recommend Mopar OEM coolant. Ya, Mopar.

 

Don't get excited; green will work just fine. Just change it out every 2-3 yrs or so...

 

I use regular Prestone or Zerex whichever is the cheapest. I have used the NAPA brand also.

 

In the summer I use distilled water and this

 

"DEI Radiator Relief
Our first test additive, DEI's Radiator Relief mixed with distilled water, brought us down to a cool and much more manageable 183 F during low-rpm street driving. Under heavy load conditions we watched temperatures rise to about 205 F, but they stabilized - unlike our initial stock setup, which didn't seem to want to stop climbing. We also saw cylinder head temperatures drop here to 191 F - a good thing since our H22A4 has a knock sensor that was probably pulling timing out from knock due to excessive combustion chamber heat with the stock cooling mixture. We suspect a slight power increase here too. Radiator Relief performed best when mixed with water alone. Once antifreeze was added to the mix, temperatures rose by a factor of about two percent, but only when subjected to extreme load and rpm. So, unless you're interested in a race-only application, there's little to lose here from adding antifreeze to the mix."

From an article in TURBO MAGAZINE where they tested WATER-WETTER,HYPER-LUBE etc. and the DEI RAD. RELIEF made the biggest diff. in cooling

 

So what? The only criteria they measured was coolant temperature! Just run straight H20 if that's all you want.

Some of us live in areas where you have to be concerned with your coolant freezing or boiling in the summer; that's what anti-freeze is for.

 

WOW !! What do you live in the north pole? There is nowhere in the cont. US where you would have to worry bout it freezing in the summer.
And running straight water is nowhere near as good as DEI RAD. RELIEF.
Did you not see where they said with stock coolant the temp.s kept climbing?
It will run about 50 degrees hotter moron.Thats why they make coolant additives such as DEI,WATER WETTER etc. genius.If you could run straight water and get the same results ppl. would do it.
But feel free to run straight water.Report back after your head gasket blows.

 

I have always used anything. Sometimes straight water to top off. Never overheated any of my 7 Volvo's nor had any water pump failures, etc.

 

Yea water to top off.Not straight water.

If just water worked so great then drag-racers etc would all do it but no it doesnt work great thats why companies have come out with additives to greatly reduce the temp.s

Did you not read the above posted article from TURBO MAGAZINE?

And thats just 1 of many articles from tuning/muscle car sources I have read on this subject.

But feel free to run straight water.
