High Cht

It sounds like some coolant was lost. Did one of the new hoses come off or did it escape past the pressure cap? If you have a coolant escape in flight you can usually smell the additive in the cockpit. If coolant gets past the pressure cap then you should see excess coolant in the overflow tank.

If any hose To/From the water pump gets warm as the engine warms up, the pump is moving coolant.

If you had a leak you will have oily coolant in the vicinity of the leak and probably enough sprayed around that it would drip from the cowling after landing.

Do you have a hot water cabin heater core that my not have been purged?

When you say the "Reservior" was empty I assume you meant the Overflow Bottle.

When you looked under the Pressure Cap on the Expansion Tank, was it empty also?

Hey Guys Thank You for the Response,

I found out what was the Problem, I had a bad Cht Sender also had the radiator flush and pressure cleaned. I have flown 2 hrs already with the temps in the Green. One of my Radiator hose came loose thats why I lost all the coolant.
