Low pressure a.c. hose keeps blowing off
Hello. I have a 2005 saturn vue, and i have been having problems with the a.c. hoses. First we replaced the high pressure hose and it worked fine for about a year. Then the low pressure hose blew. Coolant came out in a big cloud. I order a new one and take it to be replaced. They run the machine on it and find no leaks etc and send me home. 2 weeks later I'm driving and it blows again sending a big cloud of coolant in the air. What could be the problem, other than needing to replace the low pressure hose again, could there be another issue causing this to happen?
