Avid mark4 Rotax 582 break in

[William777 0]

Hi everyone I'm preparing for the first flight of my avid mk4 with a rotax 582 and the 2 standard avid front mounted cheek radiators.  I need to do the rotax recommended break in but I get about 7 minutes into it and the water temp gets up to 175F.  I've heard it's fine to spray water through the radiator but with the cheek radiator at the front of the cowling this is going to cause a lot of the water to conta I the engine and I am fearful of causing damage to the engine.  How does everyone break in there 582 engined avids?

 

thanks

Thebriman did you use a water hose and spray the water into both radiators?

Yes a water hose from the back side if the radiator.  Just sprayed the left radiator.  Just watch the temp guage and spray as needed....

One thing you could try is to get an after market windshield washer setup and install it into your plane and use it to spray water on the rads as required to control heating. i do have on installed on my model c with internal rad and use it from time to time on hot days in climb out.
