Well, I can't believe it but I've forgotten how to change the anti-freeze. This must be the start of Oldtimers Disease.
It was 70 degrees in Baltimore yesterday, and a good day to flush the cooling system. Lebaron, ''95, 3.0L V6.
I ran the engine until it was hot or at least warm.
The petcock opens with no tools -- that's nice.
I drained the coolant into one of those rectangular bottles that lie in their side; I removed the thermostat and flushed for 5 minutes with a garden hose in the radiator neck until the water ran clear. Let it drain, put back the petcock, put back the thermostat, filled the radiator with 50/50, but it took less than a gallon.
Ran the engine a minute or two until I realized that maybe I had only filled the radiator.
Went to see if I could add more coolant, but I couldn't. Usually I can keep adding and adding, even when it starts way above empty.
I added about 3 quarts, when the capacity is 8.
After sitting all night, today I could add a 3 or 4 ounces more.
Could it be I never drained the engine after all? How could that be when I removed the thermostat and the petcock and after flushing let it sit until nothing was coming out of the petcock hole.?
P.S. I also got a Felpro gasket for the thermostat and it has a brown plastic ring on the inside circumference on one side. But nothing on the card to say which side of the gasket goes up. Which does?
