Thread: anti freeze

Tweet

ive got the green type anti freeze in my aluminum radiator, should i be using the orange instead ? it never crossed my mind about it until today if that is what the orange was for or not.

I run the green stuff in mine, but I use a sacrificial anode suspended in the top radiator tank.

What do you use as an anode?

This is the one I use. Cheap insurance for $13.99.

thanks for the link rumrumm, ive never heard of that before.

My mechanic whose worked on and torn down lotsa turdwagons mentions that the green stuff ultimately gells while old orange stuff doesn't.

only really 2 diffrent types of antifreeze.. ethlane glycol and polypropolene glycol.. polypropolene glycol is enviromentally friendly and is what GM's new stuff is.. Prestone sells it under the name pet friendly ( Ethlane glycol will kill animals if they drink it, and they do all the time )... ethlane glycol, the old green stuff is cheaper, lasts a long time., and orange Dexcool is also ethlane glycol.. you could mix the 2 if you wanted.

My 97 1 ton chevy (454) came with the red and the owners manual says 100,000 miles, no service on the cooling system, except for routine topping off.

I have 80,000 miles an 11 years on it wth no trouble. It is beggining to show signs of runnig a tad hotter, which I attribute to likely sludge formation in the radiator. About ready for a flush me thinks .............

Never had any trouble with green, even after years of neglect. Kept in proper mix ( near 50-50 ) it does fine.

Recently picked up some antifreeze, and was surprised to see it was yellow. ( orange ? ) The instructions said it mixes fine, so mixed it got. No trouble so far.

For my truck, I tried some of that supercool stuff, it wasn't the ethelyene glycol, maybe propelne? It was guaranteed to make it run ten deg cooler, but I dunno if it did. You see the belt jumped off the pulleys and tangled into the fan blade, and as result the fan ate the radiator. Brand new radiator too. dammit.

I have removed dex-cool from all of my GM vehicles. It deteriorates the gaskets and pits the aluminum. It turns into a sludge and stops up everything. I first had the problem on a 97 Monte Carlo with 53,000 miles on it. The coolant tank looked like it was full of mud. Soon after the intake manifold started leaking. because the gasket was deteriorated. A friend of mine had to replace his intake on his 98 Chevy truck and another friend had to replace the thermostat housing on a nearly new cavalier.

Check out this web site. This is one of many.

The bottom line is to do preventative maintenaince to any vehicle regardless. The lines blur and people get the notion that half the systems in the car go 100,000 miles before they need service. Dump and douche your radiator- whatever it's made out of- every 2 years and you won't have a problem.

Give that man a ceeeeeeeegar !

I had a 2003 GM car that I put over 60k miles on it by 2006, never had a problem with the coolent althought he overflow tank sprang a leak. Owners manual recommended 100k between changes, but that would have been 5 years for me. A tad to long for coolant in my opinion. Not a problem since I got rid of the car in 2006.

I wonder if GM really tests their antifreeze for 100k miles or do they just use some math equation to give them an estimate of failure time. Lawsuits would suggest that if they are testing, it's a faulty test.

I change the coolant every year. Green stuff and add purple ice.

For heat transfer properties you cannot beat water. Additives increase boling point and reduce freezing point but that's all.

If you want to see a claimed 10 degree reduction in temp you must instrument the lower radiator hose intake.

I predict you will not get it ..................
