Higher engine temps
in 912 / 914 Technical Questions
7 years ago
Hi guys, I guess I can do with some advice.
Over the past weeks we have experience higher oil and water temps than usual in our 1200 hours Rotax 912 (runs nicely). We invested some time to improve airflow through the oil cooler and won approx. 10 degrees.
However, over the past hours the temps seem to be coming back up. We had hints from fellow pilots that the sound has changed so we started to think that the muffler has developed some internal defect which causes the temps to rise. We are going to check upon that somehow.
Now more questions have come up like does the water pump work as it should and does the oil pump work on the lneccessary level? If one of both or both were "poor" that would explain rising temps, too, right?
The question now is, is there a simple and efficient way to check the pumps' performance?
Thans for hints and comments.
