Dead thread revive.
I'm using this in my 1994 Volvo 940 turbo. No change from water/glycol, but what's nice is my coolant system is now zero pressure.
Heat is the same, takes the same amount of time to get to temperature.
Keeps hoses cleaner longer. No rust. My water pump seems to be quieter.
I'm planning on doing this to my 128. But I'll replace all the hoses first.
Requires a complete flush and a pre-clean with Evan's flush. I used a small vacuum cleaner to extract as much water as possible. Evan's allows up to 2% water.
