Archived Coolant leak, nearby the thermostat housing...

[crowboy]

Hello,
I have a leak that my mechanic seems to think is the front head bolt, but I think it’s the Coolant Temperature Switch, next to the Thermostat Housing, any thoughts on what you may think are highly appreciated.

You need to wash it down then run it under pressure while watching.

Yea, that and try the temp switch first....

Get one of those snap-on pump up units so you don't need to be running the engine

There are leaks that show best while running,notice I said Pressurize AND run.You can clearly see the coolant was blown by the fan
