I've got a 97 T&C, rear heater lines rusted out. I crawled under with my dremel tool and cut off the bad section of the line and also up top behind the intake. However, now that my 5/8" heater hose "fix" has now blown off 3 times, my wife said she's not driving it until its fixed. I bought the replacement assembly. I've read that the intake manifold must be removed in order to replace this. Looking at my Chilton manual, what all needs to come apart? If I don't have to separate the throttle body from the intake and everything else, I don't want to do that. I just need to get at those lines. Any suggestions?
