coolant pipes leaking

[stus]

hi all. got an 84 1.9 autosleeper. i took the bus out at the weekend, for the first time in a couple of months, and i noticed a leak from the pipe at the back of the water pump. also from one of the main, front to back, pipes. i tightened the clips up and all was good. just taken it out tonight and now got another leaky joint, on one of the main pipes. i replaced the water pump at the latter part of the summer. the main pipes were replaced 3 years ago. do i need to be concerned that its building too much pressure? or is this just a coincidence? any advice much appreciated.

Probably a coincidence but worth checking your expansion tank cap quacks
