My AE has recently started physically leaking coolant. I knew when I bought the car that the coolant seals were going, so I've always had to periodically add water and keep an eye on things away.

About a week ago, the car started losing fluid almost immediately. I'll fill it up, buzzer will be quiet, I'll drive for less than 5 minutes, and when I come back out to my car, it's all drained out on the ground. Appears to be coming from the passenger side but is NOT being evacuated through the reservoir.

I also have water in my oil...and I know that is a result of the seals. The loss of it on the ground though has me puzzled as it only recently started happening. The coolant buzzer is a mainstay, now. Pain in the ***.

Input would be appreciated.

 

I would check all your hose connections, like the ones to the heater core. If all your coolant is coming out in a matter of minutes then it has to have a fairly large area to evacuate out of.

 

The two most common spots are the heater hose at the connection under the oil filter, and the 3/8" line that runs from the cold start fast idle assembly on the back of the TB to down under the UIM.


An internal leak can sometimes be stopped for a short time with "Aluma-seal" or equivalant.
It's not permanent, but it might buy you some time.

 

Look at Sure Shot. Got the diagram and everything!

The longevity of this fix, as you'll read, is unclear. But some owner's *have* reported success. Give it a shot if you feel like it.
