Hello,
I have an intermittent coolant leak on my classic which has a XS firewall forward package.
Is it possible to remove the water pump from the engine while it is in situ on the aircraft?
In spite of doing pressure tests, running the aircraft with the cowlings off I have been on the unable to trace the origin of the leak, it does not leak cold with a pressure of 1,4 bars.
On some flights there is no discernible leak, on others I have lost up to 150 ml during a two hour flight.
There is a bit of a white deposit on the exhaust heat shield underneath the water pump. I have also found liquid on the aluminium plate above the radiators but the air passage through the radiators has always been dry.
I would rather be sure of where the leak is coming from prior to taking anything apart. Does anyone have some experience or knowledge they could share with me?
Regards,
John
