On a pleasure flight on an evening in 9/88. I experienced an overheating problem with the liquid cooled engine in the small transport. In order to keep the aircraft from losing coolant I had to retard power and was unable to maintain level flight. My altitude became what was less than desired for terrain clearance and I was flying within 300-500' AGL as the engine cooled within its limits. I increased power and slowly worked my way back to van nuys airport for a safe landing. It was found that the radiator had developed a coolant leak and had to be fixed. There was no threat to persons, property or any action that was life threatening. We have developed a better maintenance schedule for our aircraft that was involved.

Title: GA SMT DEVELOPED AN ENGINE COOLENT LEAK AND PLT FLEW AT LOW ALT BACK TO ARPT FOR REPAIR.
Narrative: ON A PLEASURE FLT ON AN EVENING IN 9/88. I EXPERIENCED AN OVERHEATING PROB WITH THE LIQUID COOLED ENG IN THE SMT. IN ORDER TO KEEP THE ACFT FROM LOSING COOLANT I HAD TO RETARD PWR AND WAS UNABLE TO MAINTAIN LEVEL FLT. MY ALT BECAME WHAT WAS LESS THAN DESIRED FOR TERRAIN CLRNC AND I WAS FLYING WITHIN 300-500' AGL AS THE ENG COOLED WITHIN ITS LIMITS. I INCREASED PWR AND SLOWLY WORKED MY WAY BACK TO VAN NUYS ARPT FOR A SAFE LNDG. IT WAS FOUND THAT THE RADIATOR HAD DEVELOPED A COOLANT LEAK AND HAD TO BE FIXED. THERE WAS NO THREAT TO PERSONS, PROPERTY OR ANY ACTION THAT WAS LIFE THREATENING. WE HAVE DEVELOPED A BETTER MAINT SCHEDULE FOR OUR ACFT THAT WAS INVOLVED.
