New Peak at Walmart? Are both of these yellows? For Aluminum Headed 351W
- Thread starter Nicasio
- Start date
Does the car have a soldered brass radiator or heater core?
The Peak Ecoshield is propylene glycol, FWIW
For a very old car, use old green coolant. Peak and Zerex still make green silicate coolant.

Old school green is easiest/cheapest found at farm supply stores. Farmers use lots of it in older tractors.
Yep! I buy mine at Coastal Supply. Durex brand usually. Sometimes they use it as a loss leader sale product so I try to stock up when they do.
Yes for Cougar. I had a clamp that wasn’t tight enough and lost some coolant.
Radiator is aluminum. I’ll have to check on the heater core
I have a Tractor Supply Co nearby. I’ll have to check and see if they have some green.
Not only that, apparently it is bio-based propylene glycol as apposed to petroleum based propylene glycol. Here is their advertising. The arm chair chemists will come out of the woodwork.

No reason to use old school green. It has downsides too. Simply get Prestone all vehicles concentrate at Walmart and mix it yourself. Saves money, protects exceptionally well. Available everywhere if you need more.
We use the Prestone in everything from personal cars to very high output turbocharged race car engines, and have found it to be perfect. Absolutely no corrosion, deposits or water pump wear. It is a long life product too, so no need to change it out every few years.
I know there are Propylene Glycol products out there that people use, including Evans/Safer/Peak. We've had nothing but disaster with them, including micro-perforations in aluminum.
