Common for the transmission line to the radiator has failed due to corrosion. You can replace the line or section it off bad part with a new line, just make sure you use compression clamps. I had the same problem and i ended up running a new line with a inline remote transmission oil filter. B&M makes a universal remote transmission oil filter and runs around $45.00. Good luck and hope it's just the line that went bad, keep me posted.

Check that the fan is turning in the right direction, in all the changes it is possible that you may have crossed the fan wires and not the fan is blowing forwards instead of backwards. Also check that there are no air locks in the system and that there is a positive flow of coolant.

Yes, it could be a few issues, I always believe to go the cheapest route first, so you are not just replacing parts to be replacing, Based on your description, Normally it would not be overflowing if your pump is not working, It could be a clogged hose, you would have to flush system to see if that was the case, but based on my feeling, i believe it is a stuck thermostat, If your tank is overflowing, it would have to be a main hose block, but i don't believe that is the case, i would have thermostat replaced, to confirm that, for a around 50 bucks (if you stay away from dealer) you can have the radiator flushed, which is a good idea anyway, then you will know for sure it is the thermostat, and they can put that in after they flush it, or you can put thermostat in, pick there brain, when they flush it, and they can point where it is, it is just a couple of bolts to take off, clean gasket area, replace with new gasket, after of course taking old thermostat out and replacing with new one.

I hope this helps you, (again, i think it is thermostat that is stuck) thanks Mike from fixya

Sounds like a problem with one of the fittings for the cooler lines.
The pipe threads could be stripped or not sealing.

SOURCE: gmc Sonoma 94 losing water no leaks not in oil or on floorboard. New water pump. New radiator cap.

your leak is likely in head leaking into the spark plug ignition area and burning of once vehicle is running check plugs for moisture before motor is hot, also can seal using blue rhino at auto zone I used on 6 vehicles and sealed all of them.

Coolant Reservior Hose


Nothing.
The second hose is the actual overflow hose where coolant escapes should the tank become full.

Coolant leaking from 1994 Sonoma. Is not near the water pump or radiator, but more towards the back of the block. What might it be?


It could be a heater hose, an intake manifold gasket, or a rusted through freeze plug. You must "look" to see where the leak is originating from.

You need to have a cooling system pressure test done, this way the leak can be found and repaired, worst cause now will be a radiator, if you keep running it, will more then likely start to leak more, where damage could happen to your head gasket, now you'll need a radiator and a head gasket replacement and maybe more, good luck, hope I was helpful.

The radiator might be clogged. Take it and have the system flushed out,and back flushed, that will tell if there is a clog somewhere. If the radiator is too clogged, it will need to be replaced.
