Coolant leak after thermostat change

I'd been noticing that my coolant temps weren't rising above 181 so I figured my thermostat was stuck open so I swapped it out. After starting it back up, once it hit operating temp I noticed coolant leaking. So I removed the new t-stat, checked the o ring and reinstalled it. Again, coolant started leaking at operating temps.

Frustrating as I ran out of time this evening to further troubleshoot. I checked closely around the thermostat housing but it doesn't seem to be leaking.

I'm wondering if the new thermostat, now that it creates a closed circuit, is now creating pressure causing a leak to develop elsewhere? Thoughts?

You sure its not leaking around the spring clamp? Or did you replace it with a hose clamp. Depending on how new the hose is, spring clamps are kind of a "one time use" type deal.

Ya,I replaced the spring clamp with a new screw type. Will try putting the old t-stat back in and see if the leak stops. If it does I'll know it's a pressure related leak and will probably have to replace the water pump. I've also heard that leaks can occur around the sending unit as well but if that's the case I might as well replace the water pump anyway.

Well it turned out to be the shaft seal failing out on the water pump. Gotta love chain reactions. Replacement was made easy using the instructions I found on here. Good stuff! Although I gotta love my wife coming out and looking at me frustrated and telling me "You're in over your head." Well lil miss, I proved you wrong!! Lol
