Thanks again Lee! I am hoping to get it done this visit, but, sadly, time is running out for me
Need cooling help please

Mike my car was about 11.5 litres empty to full.
I filled mine to the brim including expansion tank.
As the engine /car heats ….the coolant will expand and be evacuated past the pressure cap.
I did not have any eye glass on my header tank so checking the level was questionable, until I took a plastic pipe and would blow into it until I heard bubbles….. marked it at that level so easy to check.

Okay! I get it. Thanks for the tips Ian.
Progress today...of course, right before I leave. I got some fittings and pressurized the system. I heard leaks at the top forward of the engine. They are not from my new hoses, but from the thermostat housing and one bolt of the intake manifold ( the bolt closest to the thermostat. I torqued the bolt down to stop that leak.
My thoughts on the thermostat housing: when I initially took it off I noticed that the gasket surface was not the best machining. See attached photo. I recall my concern then, and so I gooped both sides of that Felpro gasket with sealant. Apparently it wasn't enough. I think I will find a better quality housing.

So I went into the radiator area where I hadn't been in a while, and I realized that I had neglected to replace those rubber hoses...I had just focused on the engine. No time like the present! I will be ordering new hoses for the next visit in a few weeks. I thought those should be in better condition up front, but I am wrong.
Here is a pic of the surface condition that they all exhibit. I am hoping these will be easier to replace with all the room there. Now, do I go rubber or silicon...hmmm?

Get yourself a piece of glass, a picture in the frame will do, and a sheet of 300 grit sandpaper. place paper on glass and wet with some clean water. Place housing machined surface face down on sandpaper and do figure 8s until smooth. All done.
I am finding it difficult to find the correct hose orientation. This might be my answer. Thanks.
Even with a surface like this the sealant should work, but you have to make 2 steps. 1 you assemble all the part with the gasket and the sealant on both faces, but you do not thight the screws. Just screw it by hand. Then you wait at least one night and you tight the screws. After it shall be leak proof.
Interesting Jean-Marc, I don't recall my exact process. But it sounds like that would be easy enough to try. I think I will, next visit. Thanks!
I had to retorque my silicone hoses several times ove the years as they started leaking after a while.
More than I am used to with regular rubber hoses.
Replaced most of my Mikalor clamps by regular clamps also after my build as Mikalor has just a narrow range of clamping, not enough range to clamp more to stop the leaking.
Three years after finishing my build.

Have you checked the thermostat recess depth in the housing? If it’s not deep enough the thermostat will hold the housing off the manifold and the side port will not have enough gasket crush to seal.
That’s where it appears to be leaking from.

Great idea! I will check it when back there.
