I replaced the heater control valve and my husband and I drove it a few miles up the road. When we got back my husband had a noise and then coolant gushing from somewhere. When I looked the heater control valve had separated. It is a 6 port heater control valve.

I agree with greg. Also, if you are using aftermarket parts, try a NAPA Balkamp # BK 6601321 they are usually a better quality part than some other stores carry. May cost a bit more but worth it!
