Hello all: Last night, while driving home, the temp gauge on the dash was red. I pulled over to find that coolant was boiling out of the overflow reservior. The water pump was replaced by the prior owner, and no hoses appear broken. In reading the posts, it appears that it could be the thermostat, radiator cap or head gasket. Any thoughts and advice are much appreciated. Cheers.
