Townace Overheat Problem...

[Toyoluva]

a few weeks back on the way back from work my rad hose popped off so i pulled over and changed the pinch clip that was fitted and put on a jubilee clip.

after less than a mile another hose popped of, (by this time i was starting to get worried) anyways i refit that pipe and then drove on for less than another mile when another pipe burst.

it was located under the drivers seat and there was no way to fix that so i had to get a tow home.

when i got home the first thing i checked was the oil to see if there was any water in it but luckily there wasn't.

i'm thinking its either the water pump or the thermostat... i need to know if my assessment is correct.

help needed urgently.

thanks.
