Coolant Loss

Yahoo Message Number: 2585
I've had the damndest thing happen to my '00 Magna. While on an extended trip, I noticed coolant leaking from the area of the radiator. I decided to refill it and see how bad the leak was while I continued on the trip. Beleive it or not, it never leaked another drop.

A few days later while looking at a new Intrigue, I noticed CC has added a small overflow tank for the hose coming out of the pressure cap. I looked at my Magna and the overflow hose is sealed shut so no coolant could be released. I don't know whether this is the cause of my coolant loss but it sure seems like it could be.

Does anybody have a clue why CC would seal the overflow hose and later add a overflow tank?? jerry in NM.

Hi Jerry,

It's hard to respond your situation.
To give some insite, please see cc owners user group message no. 2391 - addition of auxiliary coolant tank.

Hi Jerry,

Regarding coolant leakage, I had a problem with my 2000 Allure leaking coolant. The problem was loose hose clamps both at the radiator and to the heater core. I learned something from these leaks. A loose hose clamp usually leaks when the engine is cold.
After things warm up, the hoses expand and seal themselves. You might look at your Magna for coolant loss when the engine is cold.
If it is loose hose clamps, that is the best way to find them.

Thanks for all the input. I think I understand what might have happened. Since the overflow hose is plugged and can't releive the pressure of the coolant expansion after a hard days run and also a change in altitude, the pressure is released through the weakest point. In my case it was a weak hose clamp and the overflow hose itself at the pressure cap. Once the hose started leaking it continued down to that level. Why it didn't leak again is not clear. It might be that the hose clamp is looser when cool and tighter when hot. That doesn't explain why the pressure wasn't lowered also when it cooled off.

I'll probably never know what happened since I damaged my radiator later and had to have it completely removed and repaired. I have installed an overflow "tank" of sorts and hope this fixes the problem.

Thanks again for all the help. jerry in NM.
