Stuck low clutch and thermostat housing leak

Featured Replies

99 legacy 30th anniversary ed., 2.2l, 5MT, 200K mi.

 

Two questions:

 

1. Since mid-summer until about three weeks ago the clutch pedal was sticking low on occasion. I'd flip it up with my toe and it would go up with a thump. Recently, though it's been stuck low, so even after I flip it up, it would travel toward the low position where it disengages, very easily. I checked a few posts regarding this, they all seem to point to hydraulic problems. I glanced under the hood and could not find an additional reservoir for hydro-fluid for the clutch. Is this pedal problem specific to hydraulic clutches? Is there a sure way to tell if my clutch is hydraulic? What could be if my clutch is not hydraulic?

 

2. A coolant leak has developed right after I replaced thermostat. Is there a special sealant than must be used between the thermostat cover and engine block? Hynes does not mention any.

 

Thanks in advance for any advice.

The hydraulic reservoir is on the firewall, between the master cylinder and airbox. If not hydraulic there will be a cable that runs from the clutch pedel to the bell housing. If you have the proper thermostat, it has a rubber seal built into it, so no sealant is recomended. Make sure your lower hose clamp is tight...and make sure you didn't over tighten and crack the plastic thermostat housing. If you did, I might have a spare one. Good luck....

Did you put a new gasket on the new thermostat? It should be replaced when replacing the thermostat. It does not come with the thermostat, at least not the OE thermostat.

Use a genuine Subaru thermostat and gasket only. Don't drive the car with any sort of leak...Head gasket failure on these is far to easy to accomplish.

 

Change the fluid (turkey baster) and bleed the clutch master (bleed like brakes).

One more thing, this clutch deal bothers me a bit...the pressure plate gives your pedel the resistance/rebound..., if the clutch pedel drops to the floor with little resistance (by itself) AND the clutch disengages...than you need a new pressure plate (or clutch assem I suppose).

Outbackus, the clutch pedal doesn't drop to the floor. It stays at about 1/2 to 1/3 of its normal height. If I flick it up to its normal height with my toe and then depress it, it travels the first 1/2 to 2/3 of the way much easier than it used to before it stuck low. I appreciate the suggestions. I'll try them and report next week.
