Hello,
Straight to the point: Are we required to "burp" our cooling systems?
I read multiple posts that swear by burping, and only a few that say it isn't required.
But it seems to make sense that the system will naturally expel air through the radiator cap/overflow reservoir upon cooldown. (Provided that you keep the fluid level in check so air isn't sucked back in)
But then I read all the issues that can happen with air trapped in the system...
History: I recently repaired a coolant leak. It appears that I've only lost less than a liter of coolant (the rubber heater hose clamps next to the t-stat housing were bad on my 420a). I elevated the car, turned on the heater full blast, waited for the thermostat to open, squeezed hoses, and added coolant as necessary.
Seems like I spill more coolant that the amount I try to top off.
I know about that special burping funnel, but for $20-$25? :/
