We have a 91 camry that used to only be driven in town. Last week, we drove it 70 miles over freeway, mountains. When driven over 50MPH, it got hot so heater was turned on. It still overheated losing water/coolant. The oil gets changed on regular basis, in fact was just changed from 10/40 to 10/30 because of warmer weather before it was driven. Thank you for your help in advance
Got the problem solved... #1 pulled the radiator out and flushed the whole system( put a water hose in thermastat housing and let the car run) #2 installed new thermastat #3 installed new radiator...now she's runin like a champ

if had driven threw a large amount of water and hydro locked the engine yes you could have damaged the heads but also the connecting rods could be bent having such low miles on the car i would not but a engine with so many miles on it if you have full coverage on the car call your insurance company and see if it is covered a deductable is cheaper then a engine and a rebuilt engine would be a option
First question is what constitutes "overheating". Since the car has been parked for years, the thermostat could be sticking closed. The cooling system could have air pockets and need to be bled. The water pump may be corroded inside and not pumping enough volume. If the gauge goes above half way, the fans should start up. But half way should be more or less normal, not hot yet. I would look at flow problems first, beginning with removing the thermostat and driving it without one for a few days. Also check and see if there is a process to bleed the cooling system of air.
first of all, was the water on the passenger side from the air conditioner or a leak (what color was the fluid?)-the cap has to be tight, otherwise it will not hold pressure, so that has to be checked before you set off again-push down as you turn the cap clockwise, and it will not hurt to have water in the system (it actually transfers heat better than antifreeze) but it has a much lower boiling point, so the cap has to be tight. Pay attention to the temperature gauge and do NOT overheat it-it is an aluminum engine and they do not tolerate excessive heat. Take your time, no AC (although the AC being on can keep a good cooling system more stable since the radiator fan is forced on when the AC is running, so you can, within reason, experiment)-no matter what, just don't let it run hot-not worth it.
Running so few miles has accelerated the aging of the battery - the battery never had a chance to fully recharge in such small trips - so now you have to replace it a year sooner than usual.
Just replace it.
if it's not going onto the ground, and it's not being burned, check the positive crankcase ventilation and the exhaust gas recirculation valves for oil seepage...also check your air filter, if its got oil on it replace the pcv valve.
shouldnt worry about compression ratio pressures as yet ,if all gauges going up the swanie then either altenator is overcharging and the voltage burnt things out or a gremlin got into works when you visited the mountains in whick case call ghost busters ,must go first customer has arrived
