1998 SLK230 R170
Thermostat has been sticking open so the car won't stay warmed up. Then it snowed here and for 2 days it worked perfectly. Today the car overheated and I'm assuming it got stuck again but closed. The pressure caused a small crack in the pressurized coolant tank to actually break open. I may have also broke it more geting the hose off. I know I could just keep filling it religiously but I want to repair it. New ones are $90 but all these repairs are adding up for me.
