I have a similar thing going on. My Saab blew a coolant hose yesterday, which I temp fixed with gaffer tape and a coolant top-up. I've now ordered a complete kit of after market hoses and clamps, since the existing hoses are all 10 years old so it's only a matter of time before others go. Basically I've watched enough ChrisFix recently to feel confident enough that I can do this myself without screwing it up.

You really should. I've found it extremely relaxing and enjoyable, and it's useful learning how to repair your own vehicle.
