have seen great reports about this product and have access to some I have a 1985 3.0 QV Does anyone know the total coolant capacity, I can't find it anywhere
Total coolant capacity should be 24 liters or 5.2 imp gal or 6.25 US gal (under normal water use 50% recommended as anti-freeze)
Interesting - just noticed that reference to 15 liters. My copy of the Mondial 8 service manual (both 2V and 4V) gives the capacity as 24 liters (same as the 3.2 version). Mind you nothing unusual to see printed mistakes in their manuals (the aircon compressor capacity is given as 56 pints!). Not as bad as some of the Alfa manuals though. Superperformance give the Mondial 8 as 15 liters with the 3.2 at 24 liters and the "T" at 20 liters.
I've ran this before (not in an F car) and coolant temps were very high. Just thought I would mention it, interested to hear your results.
Similar experience here, my own thoughts are to think long and hard before changing coolant type in these engines.
Please don't take this the wrong way, but I'm wondering what problem the "Evans Waterless Coolant" is trying to solve? Does it help prevent corrosion or supposed to somehow allow the car to run cooler? Why not stick with plain old Preston 50/50 and change the coolant every 2 years?
I remember reading about this in the Porsche forums - they talked about a perceived reduction in corrosion. But with proper maintenance, the regular coolant should be perfectly fine. Also the evans product is expensive and the process is more expensive to change as you need to get rid of all the water in the system. Not worth the effort IMO.
You can run it unpressurized. I run 60/40 glycol unpressurized two years / 9000 miles without adding an ounce.
The big thing is there is very little pressure in the system with the Evans coolant, so much less chance of blowing a hose, radiator etc. I have it in my BMW, you can take the expansion tank cap off while the car is running full hot and there's a very small puff of air and no boil over at all. With normal coolant it boils over immediately if you do that. This will overall put a lot less stress on the cooling system.
I'm assuming that this is because it doesn't turn to steam? Can you bleed air out of the system just as easily with the Evans coolant? (I installed the EZ Bleed screw...)
Yes since it's basically pure propylene glycol the one advantage is you can run a very low pressure system. (no need for high pressure to avoid boiling). No problem bleeding the system as you would normally. Downside is it's less efficient at heat transfer when compared to a traditional water/antifreeze mix.
