I have had a 13 pound cap on the overflow tank and have gone through 3 heater control values in 5700 miles and they all leak.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">So now I am thinking about a 90 degrees manual valve with a very short handle that would fit in the stock location as the heater control valve utilizing the bracket of the heater control valve that would allow me to bleed all air from the motor at the highest point, which I believe is the heater core,. The idea is try and and retain as close to possible the stock correct look, be able to bleed any air when refilling the radiator and have the ability to manually turn on the heater once to twice a year as I live in a very moderate environment and drive the car year round.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Any ideas as to a part number or manufacture that would meet these requirements or any other ideas?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thanks</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Joel Martin<br></div></div></body></html>
