For a SBO, what is it?
I'm running 50/50 and I tested it with one of those ball tester thingies and it came back +20 to 215. Personally I think this isn't good enough. However I tested a bottle of straight antifreeze and it back the same way
Doesn't sound right.
Anyway, The car overheated about a month ago due to the belt breaking and not turning the waterpump. everything's fine now, but 215 for Philadelphia area summer driving, just doesn't seem good enough.
I have a 180* thermo and a 195* (temp on) fan. It wasn't too hot last month and the temp was creaping up to 200* while I was stopped. Outside temp on this day was in the high 70's
