ok the latest and last update..
1) the tube in the middle with an extra hose in the middle had an issue as the middle (original rubber) hose was too short hence I had a very short overlap at the engine side
..understood .. and my mistake!..will professionally fixed!!! big smile!!!
2) my thoughts:
- we understand the svivel tank is doing its job, ok, then if it opens the pressure valve say 13 psi, releases overflow due to pressure water goes into in the overflow tank.
- well if the cooling system looses water!! my case,, woow what then? Garage floor? Yes we do!, I did.
- ISSUE the old fashened overflow design is in my opinion crap, reason: you do NOT SEE if cooling system is sucking OUT or IN/Stable lize OR is EMPTY as in my case. To see the level of the overflow you need to open the svivel, well is normally full and THEN you NEEED to open the OVERVLOW if the is an issue on cooling or just to see if the is cooling liq. level adequate. .What an issue to do this..as you need a rope funneling in to see how full it is...
...an al of my vintage cars I just open the hood, ake a look a the ovevlow,and close it. (for Corvette C2 I need to open the lit on the tanke and the we go). BMW39 540, BMW30 25, Polo, Smart etc..I run 6 (modern cars)..
think you understand... overfow Tank without level idiaction is CRAP ! ok, i am not an originality fetishist. Best to me apppears to me is a transparent plastic tank to do the job..
cat is hopefully running Wednesdy..
P.S.: I will throw the 125 USD overflow tank on the junk jard (very big smile). lost 5 cases of corona free beer.
