Good afternoon,
I have about 50 hours on the 912ULS in my kitfox and am having a little trouble keeping the cooling system drips at bay.
Where I am getting the drips is at the aluminum "T" s - which patch in for the heater - both on the 1/2 inch fitting for the heater and on the 1" connection at the heater "T".
The 1" hose and aluminum "T" s came from skystar, just before they flushed themselves in the bankruptcy. The clamps are the traditional screw drive clamps common on auto radiator hoses.
There are no leaks at the lines on the engine going to and from the cylinders and none at the fittings going into the heater core, radiator or engine. (Note - the cylinder fittings use spring clamps and the heater fittings have nice sharp barb fittings - unlike the aluminum "T" s which are fairly rounded.)
What I have done is incrementally tighten the clamps on the "T" s, hoping that eventually this will stabalize the problem, however, no luck so far. Also - There is no sealant on any of the connections.
I am wondering if there is some basic incompatibility between the hoses, clamps and heater "T" s - but that is only a wild-elbow guess on my part.
Anyone else had any issues with this type of problem? If so, what works?
Sincerely,
Dave S
