Default Coolant leak away from home

Hi Everyone! We are on our maiden voyage in our now-to-us 86 PT40. We had the coolant compressor hoses replaced before we left (more on that later). We have been sitting, plugged in, for 2 nights now. This morning I found that coolant has been leaking overnight from the rear of the engine. Probably less than a pint (always looks worse spread out on the pavement), but its been shutdown for over 24 hours. I haven’t had time to fully backtrack the leaking, but it seems to be coming from the vicinity of the water pump return manifold(?) on the left side under the pump.
Two questions: first, what might cause such a leak on a cold engine?
Second, any recommendations as to a quality service center in the Boise area?

Thanks in advance for any help provided!

Check your hose clamps. When the weather gets cold they may have a tendency to start seeping. It seems like every year about this time I end up checking them and find a couple that need tightened a little.

Like Kevin said. Check your hose clamps. I had leaks in the fall with cooler weather. I changed all my clamps to Breeze constant torque and doubled up some of them and that solved it.

Thanks for the insight! I did find a couple above the wet area that took a half turn of so. Tomorrow it will get leak checked to see if that fixed it. We have a 2500 mile trip back to Lower Alabama so I pray that a loose clamp is all it was.

Did an engine run today and NO LEAK! Thanks to John and Kevin, as you’ve saved me a trip to the shop. I would not have thought that the system, cold and depressurized, would leak like that. Once again, the collective knowledge base of the WOG has saved time and money for the new BB owner!
