Unable to locate TB42 coolant leak - what are some of the less obvious areas?

[dom14]

Thanks guys! I'm certain the water pump is leaking so I'll pick one up today.
I did the coke bottle trick when i replaced all the hoses etc however on the way back from Clare, when it sprung the larger leak, I was regularly topping it up uphill,squeezing hoses and doing the best i could. Fingers crossed!

Side note, but what are good hose clamps to use? I tried one of those worm drive stainless steel items and that was supposedly good quality and it was rubbish.

Hose clamps that come in little plastic box as a kit may be rubbish. But, if you buy them individually in stainless steel form, they are usually good quality. Another thing I did when necessary was to use two clamps, instead of one, when I was using them from an inferior quality kit.
The stainless steel clamps in Bunnings are usually good enough, or you can buy them from Burson, Repco, Supercheap, Autobarn, etc, but usually the same. You shouldn't need heavy duty screw clamps on coolant hoses.
