Dont think its head gasket. Never heated up until i put water pump in.If the check engine light is on, trouble code might suggest oxygen sensor(s). Those things don't like coolant at all. Yeah I just suggested a failed head gasket. For a more positive note... The copper colored Head Gasket Fix from Barsleak really works. It's been in one of my 96 Camrys since late Sept'. Check engine light went off the very next day ( about 15 miles ) and has never came back on. Yes I struggled with the decision to pour some snake oil stuff in it. 23 bucks and only need half the bottle for a 4 cyl? YouTube videos convinced me to give it a try. At 28X K miles this car really isn't worth the cost of head gasket renew, especially if a reconditioned head is needed. For now, we're getting ALL the good out of these 'yotas.
@Ddaddy i found the reference to jacking up car, the bleeder screw on rad. Going to get the new t-stat and see how that goes.
I have a chemical test for combustion gases in coolant, but the vacuum test i did tells ne otherwise.
