Yeah anything under 12 and you know its going bad. I think it'll be closer to 14 when running.

taking apart the clutch now to try to figure out why the pedal goes all the way to the floor and stays there. No obvious signs in the disassembled pedal, taking off the master cylinder next.

When a car battery doesnt reach at least 12v after a charge, its likely no good.

Also some batteries will get to 12v but wont have the amperage to turn over the starter.

Should be around 13-14volts as already mentioned.

The battery should read above 12v. More importantly are cold crank amps, amperage is a far better test of battery health. Any auto parts store can test that.

Check your alternator. It should be putting out over 13v. Most auto parts stores can test alternators as well, if you can't get the vehicle running.

An easy way to test an alternator is to start the vehicle and then disconnect the hot battery cable. If the vehicle continues to run, the alternator is providing enough juice to keep it going. If the vehicle shuts down, it was running off the battery's juice and the alternator is shot.

As for cooling systems, I would highly recommend investing in a pressure test kit. They aren't that expensive and will save you so much hassle. You can test both the radiator cap and the entire cooling system. You basically put pressure in the system similar to that which exists when the engine is running at temp, and the pressure is going to push coolant out anywhere it can and if there is a leak, you'll find it.

Before you tear the transmission away from the block to check your clutch, make sure the clutch pedal cable is attached at both ends, and isn't broken. If your vehicle has a clutch cylinder make sure you do a thorough check of the master and slave cylinder for leaks and make sure it has enough fluid. If it doesn't, the pedal will go to the floor and won't come back up just as you are describing.

Best advise I can give you from my years of working as a diesel mechanic at a Navistar/Internation/Ford/Isuzu dealership is this: always start with the simple solutions first. Work your way to the more complicated issues, you'll make sure you don't miss the small details that way and may save a lot of time and money.

thanks for the detailed response :grin:

Thats where I'd been looking so far clutch wise, it seemed like the issue had to do with the pushrods connection to the master cylinder.

Also, the cylinder was totally empty when I first started working on the truck again. So there's gotta be a leak somewhere. I'm wondering if its the slave cylinder since putting new fluid in the master cylinder didn't produce a leak, and as far as I can tell all the lines look good.

occams razor is the lesson of life lately :cheers:

hmm, I hope I'm not leaving the clutch lines open too long, forgot brake fluid is hygroscopic. Should I maybe plug up the line?

Should probably flush the whole system of fluid?

Pushing on the piston in the cylinder squirted fluid all over me so we're all good there...it seemed like the return spring for the clutch pedal itself was good, scratching my head a bit over here. You said a leak in the system would cause that pedal symptom though, so I guess I'll go in search of that.

I'm wondering if the line might be clogged since the pushrod seemed to work right, but never seemed to push fluid out of the master cylinder. I had pumped the pedal repeatedly with fluid in the master with no change in level. bad idea to put air through the tubes probably

I guess I probably should have realized this sooner but bleeding the clutch system revealed the leak immediately :aweyeah: twas in the slave cylinder

wasn't a total waste of time though, master cylinder was all full of guk that needed cleanin

I'm feeling a lot better about this now, get myself a battery and a slave cylinder and I can at least give her a test drive I hope

Just posting here so I can find it later and see if you got the truck to start.

Bringing a car back to life is really exciting, even if it's not my car :lol:

I haven't done it personally (yet), but I have a car that's been sitting for about 6 years that I'm hoping to get running again when I get my tax return.

Yeah I've never worked on a clutch before. Next time post a few pictures, I like learning new things :smile:

Well, put new brake fluid in and pumped the brakes to try to reveal a leak and all seemed well, possible I just let the fluid get low...though I'm still suspicious. Maybe a problem will reveal itself when I get someone to help me bleed them later

That oil leak near the spark plugs I may have mentioned earlier is worse than I thought, my oil gets depleted quite quickly. blerg

edit: well the good news is that it appears to be the least intensive engine oil seal to replace. Though I would need to jack up my engine enough to remove one of the engine mounts, probably sounds scarier than it is :lol: But yeah, just looks like the camshaft cover gasket, leaks all over the spark plug area and smokes. Explains why my old plugs were all oily, oh shit my new plugs! :shakefist:

well I've got the new slave cylinder installed, that was a real bitch. Had been doing really well with my anger problems throughout this project but that cylinder is now well aware it's a shit eating cunt.

When trying to bleed I was only getting a tiny blip of bubbles at a time and no resistance in the pedal. So I tried pumping the pedal with a closed bleed bolt, this finally got some fluid through the system, no leaks.

But the pedal still doesnt come back up after being depressed, gonna try to bleed it again later to see if its acts more normal.

Thinking maybe there's something wrong with the master cylinder, might as well just replace it eh. The spring on the pedal itself appears to be in place and work right, dont think thats it but maybe.

Alright, clutch pedal is coming back up now after pumping it for a while and sitting overnight. :awedance:

Found the leaky brake hose in my accord and about to swap those out.

How bad is it to be lazy about bleeding brakes/clutches for a few days?

Really depends how bad the brake fluid is. That stuff is made to compress under pressure (or the opposite?) and when it gets really old it won't do that anymore. From one second to the next you could have pedal to the floor and nothing. Happened to me on an off ramp and I shit myself. Barely stopped before the intersection on 1/4 mile ramp.  I bled all lines and this dark green/black fluid came out.

Yeah the fluid in the cylinder itself is dark and cloudy compared to the clear stuff straight from the bottle.

gave charging the battery another go and after a long time it got to a full charge.

On attempting to start the truck with this it made a rapid but weak futututututtututut noise. Not a normal cranking sound.

Full charge battery is putting out 12v? or it's the 23 year old battery still?
