Tell us the whole story OP.
You bought a used vehicle and have been having a lot of issues? You can't replace radiator lines yourself? There are just spring clamps at each end! You just need pliers to replace them. Drain the coolant and replace it...but I get you may not have time or desire to mess with it.
Any older vehicle will have this as maintenance, the older the worse. At least you won't have to deal with the infamous intake manifold gaskets, injectors and distributers on your 2007. LOL
Most folks that drive the older rigs don't mind working on them and getting their hands dirty, some actually enjoy it. Starters, alternators, HOSES, belts, brakes, suspension, etc. It's all maintenance. Some just don't have the money for a brand new truck with a warranty. Or don't want to. Which one are you?
