mixing coolants??

I changed the thermostat in my 90-240 the other night. When I was all done, I added about 2 qts of prestone to volvo c coolant. Id forgotten that I hadnt yet converted this car to prestone. How worried should I be. Will I be ok with this mix for awhile. Or should I drain, flush and refill immediately?

Thanks

Lawrence

Don't sweat it immediately. Flush and refill with the next nice weekend. Flush really well though. But it's not instant death.....in fact I'll bet some people have gone many miles this way....
