Subject: Re: Clutch slave cylinder and leaking coolant
Content-Type: text/plain; charset="iso-8859-1"
I wonder if tightening all clamps and such would make a difference. Don't
things shrink during cold temps? And expand during hot?
One solution I've thought of is to use BOTH the spring clamp and screw
tight hose clamp next time I do coolant servicing. I'm wondering if the
spring clamps would naturally tighten when colder temperatures cause
shrinkage. I have both types of clamps on my expansion tank. Redundant? I
wonder?
Anyone know if this would make a difference?
