I have a 1986 300 E. I went to put radiator fluid in the overflow tank and noticed the small hose at the top of the overflow tank was cracked so I pulled on it and it broke in half. I was wondering where that hose went to? I see that it goes back into the firewall/dash area, but I wasn't for sure what it did. I don't think it goes to the heater core because it's a pretty small hose. Also, should I replace that hose or can I just plug it up to prevent antifreeze from leaking from there?

Thanks to everyone in advance.

It is an overflow hose that "directs" excess fluid to the outside world, instead of causing havoc by wetting a hot engine. btw: you have a similar, not so obvious, tiny hose to drain HVAC condensate - located rearward of oil pan.
