Waterless coolant

The shop wasn't trying to get new Business, what happened was I stoped at a shop along my trip path because of a overheat and they said my antifreeze was way past due, they drained it and I watched, it was dirty and rusty, they changed it and I was on my way, ( in Oregon) I arrived in Vegas a week later and my water pump failed, and when they pulled it apart everything was rusty.
I had not changed the antifreeze in about 5 yrs or about 60k,
So my bad...( bad to about 1,200.00)
So I was thinking the waterless would prevent rust, but I'll stay with the normal stuff and change it when I should...

It is important to change coolant every 50,000 miles, something I learned the hard way. Old coolant loses it ability to prevent rust and one of the first things to rust out are metalized head gaskets. So after losing some head gaskets to rust on a chevy V8, I always change my coolant every 3-4 years.

Poster was making a joke. Just like an old VW bug owner being told they needed a quart of antifreeze.

To the OP, prior poster stated that 97% old green had to be removed to prevent corrosion with the new waterless coolant. That one statement alone would send me running. Those poor people that swapped out OEM DEX-Cool for green really had major problems after that.

Honestly, I would wonder a little about that shop you're at. I would have them explain in detail how the changing of the antifreeze caused your water pump to go. If it sounds like they are pulling your chain to scare you into doing everything with them, then I would start looking for a better place to do business with.

Will the waterless coolant do anything to remove the mineral buildup inside your old radiator? Is the specific heat transfer greater than 60-40 water and antifreeze? If not I don't think it would be worth it for an old radiator.

Here's a LOOONG article about (a specif) brand of waterless coolant -

http://www.norosion.com/evanstest.htm.
I do not know if "your" bend of "Waterless Coolant" is the same thing or not, but it gives some things to think about

"SUMMARY OF FINDINGS

Conversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it.

97%+ removal of all previous coolant is mandatory in order to prevent corrosion.

Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators.

Engines run 115-140oF hotter (at the cylinder heads) with Evans products.

Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion.

Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously.

Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water.

Engine octane requirement is increased by 5-7 numbers.

Computerized ignition must retard engine timing by 8-10o to prevent trace knock.

Engine horsepower is reduced by 4-5%.

Accelerated recession of non-hardened valve seats in older engines is possible, due to brinelling.

Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate.

Coolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity.

Race tracks prohibit Evans products because they are flammable and slippery when spilled."

But can your lawnmower pull your motorhome...lol

I use waterless coolant in all my lawn care equipment and my chain saw. Also used it in every motorcycle I ever owned. Worked great for me, and didn't cost a penny.

Cost is 80% of the full strength. Distilled is just $1 per gallon.
Nothing wrong with using premix to top off the tank.

Also if you have rinsed out the old coolant with distilled water you still have a lot of water in the system after you drain. If you just add 50/50 mix you will never have actual 50/50 in the engine because of dilution.

To the OP, stuff like this is one more reason I would stick with OEM green. Not saying your waterless coolant would have the same issues, but it would be a shame to spend that type of money and make matters worst.

Dex-Cool headaches.
