I forgot, one other thing... I run silicone hoses, for those not doing so, you are doing yourself a disservice.
Most new cars use them and also use long life coolant. I have a 2006 Xttera... still has factory coolant and factory hoses at 177k. Still runs as cool as ever.
With silicone I should never get a leak. But if I do, yes you can run water in the system... you just need to flush it out and clean the system before recharging with Evans....
Just an fyi... I've been around Deloreans longer than most... Vin 3254 has been in my family since a month before BTTF made the car famous in 1985...
