Hello everybody I'm new to the site and hoping someone could give me some advise on what to do.. I have a 92 Camry 2.2L I've replaced the radiator about 3months ago. Then 3 days ago i was driving on the freeway at about 11pm and my temp was just above the C on my gauge.. so the following day I replace thermostat after that it was staying in the middle of hot and cold on the gauge but after I drive it about 10miles And turn it off I heard bubbling sound coming from engine.. so I popped the hood and seen bubbling in the reservoir.. "wtf" I said to myself.. so I take my Bros car to AutoZone n buy a ECT sensor more coolant and a radiator cap.. so I drain coolant from radiator change ECT sensor put fluid in and new cap and started it.. let it idle for about 30 mins and usually the fans will turn on but they didnt.. when I put a on they will turn on.. so didn't think too much of it.. took it for a quick spin then went back home.. didn't hear no bubbling sound.. so I'm thinking it's fixed.. popped the hood to just look and I noticed the upper radiator hose is almost twice its size... What in the hell did I do wrong??? Someone plz tell me!!!!
