'97 Aero 40,500 miles. Have owned 5 years, no major problems and few minor ones.
"Check Radiator" light started coming on intermittently a couple months ago. I checked coolant level, it was fine, and temp was normal so I figured bad sender unit. When I took it for inspection I had it checked and was told under pressure test there was a drop at a time coming out from where the hose goes onto the radiator. Fixed by tightening hoses to spec which necessitated removing turbo to get to the hoses (?!). Anyway, I was charged an hour labor and problem solved. But then - after having only driven about 15 miles, I had no clutch. Luckily I was near home, so put car in driveway and I find that when pressing clutch, can hear fluid squirting out near the firewall and can kind of see same fluid (hard to see in there but did also see it drip under car after test). Not good! Now here's my questions (in order of importance):
1. What has to come out to get to where the clutch hydraulic tubing seats to the master cylinder, since I'm guessing this is where the leak is (seems I can wiggle the tubing a little and it should be very tight in there). It looks like at least the battery... and..?
2. If the master is good, which I'm assuming at this point, should I rebuild it anyways as a matter of course? I suppose the master could have failed to the point where fluid comes out, if that's possible, but I don't think it would go from working perfectly to totally failed all at once.
3. While I do believe in coincidences, is it possible that they (mechanices) did something to cause this? The only thing I could think of would be to really reef on the tubing up closer to the firewall and that's pretty far from the front of the engine. It just seems weird that it would happen right after they worked on the other problem.
4. How can the 'check radiator' sender be so sensitive to know that a drop was lost? I mean, through these couple months I checked the coolant level often and visually there was no change in level, so it's not like lots of it was leaking. What's it measuring to know a drop was lost?
5. Do you really have to take out the turbo to get to the hose connections? That seems like a hell of a design. Maybe they meant they had to disconnect some of the tubing, that might be more likely.
Sure would appreciate any help! Thanks! (Oh - and - I LOVE the car)
