sprung a coolant leak today

Had the exact same issue with mine, post HG repair. Throttle body heater hoses leaking all over the driver's valve cover and running down onto the drivers side primary o2 sensor. Tiny hose clamps strip out before they get tight enough to seal. The hoses are sized poorly in relation to the size of the TB heater fittings, or mine seemed that way.
Although I sincerely hope this is the source of the leak, I cant help but be skeptical because I replaced the throttle body heater plate and gasket well over a month ago and the leak just started yesterday. Tomorrow when I get out of work Ill give it a try though. Already purchased new clamps.

Yeah I see your point there. Although one of the hoses may have failed where the clamps engage the hoses. Did you reuse the old hoses when you replaced the TBH? Good luck with things either way.

I used the same old hoses when I installed the new kit. I have some fuel hose that i can use thought i need to... thanks man.

I had replaced all of the hoses on my truck last year, then suddenly about a month ago I noticed the reservoir dropped about an inch in one week. I found that the heater plate hose had started leaking. While hunting for the leak I saw evidence of the head gaskets leaking as well, but the main culprit was the throttle plate hose. It just started leaking. After I did the head gaskets and put it all back together the hose still leaked. I was able to get it tight enough using clamps made by Ideal. They seemed to be the best made of the ones I had in that size and I was able to really crank on them without them stripping.

Engine temps are fine according to Ultragauge and despite driving 10 miles home from work then going out to eat then back home no more fluid loss. Checked again this morning before I started the truck and shes not leaking. This is very strange indeed. But I decided to top off the coolant anyway before I left for work. I dont see how the truck can leak a tablespoon or so of coolant in the parkinglot then drive around part of the day and not leak anymore the next day while parked. Must be a Rover thing
Ill swap out the old hose clamp tonight or tomorrow and see what happens.

I loaned a thread chaser set and A/C vac pump from Autozone when I did my headgaskets and a pilot bearing puller & slide hammer from PepBoys when I did my driveshaft rebuild.
