I have an 87 mid size Blazer and it has a hydraulic clutch system. I lost the clutch while driving and pulled it over to take a look. The fluid was all gone but I couldn't tell where it went. It was -40 degrees C outside so I filled it back up with DOT3 and it lasted 4 days before suddenly draining again. I have looked under the pedal, followed the hoses and on the ground.... I can't find where the fluid is going! It is still freezing cold outside so I have 5 minute intervals of looking. If anyone knows where to look I would greatly appreciate it.

Thanks.... Desperate in Canada

 

have ya checked the slave cylinder? for the clutch... Theres a poss that the metal line froze and cracked on the bottom of the line so when your driving you cant see it leaking cause all the fluid is already is gone.... fill it back up have someone sit in the truck and press and depress the clutch pedal look underneath for fluid dripping....if your in canada, ive been there personally i know it can get damn cold... Ive been there when it was 70 deg below 0 -nuthing was moving!!!!!!!

 

I'll give it a try... thanks.
