I have a 93 Camry XLE V6 with a coolant overflow problem. I drove abut 10 miles and put it in the garage. When I got out, I heard coolant gurgling. I popped the hood and saw that coolant had filled the reservoir and then blown out the end of the tube. When I pulled the cap off the reservoir, I noticed that there was no tube from the cap going down to the bottom of the reservoir. Could that be the problem? Does that mean there is no way for the cooling system to suck coolant back in?
