My radiator cap popped off while driving. Coolant everywhere. I filled the resivoir back up but it's still overheating and the heat isn't working
Ahh Ha! Let it cool and added quite a bit of coolant straight under radiator cap. Let it sit for awhile and fired her up. No overheat and heater cranking nice and toasty again!
Keep an eye on the coolant level and for excessive cooling system pressure, you may have a head gasket problem that caused the radiator cap to blow off.
I had the same issues. The mechanic told me that I might of had a head gasket issue. I was not. Took and replaced the Radiator cap, refilled it, let it cool. Then was good to go. My heater does not work well. But I don't think it was because of that.
