Just want to say that since buying a 93 camry with 210K miles a few months ago, this forum is a godsend.
Ok, now for the new problem...
My wife tells me "the car is smoking", so I pop the hood expecting the worst and see coolant all over the front of the engine compartment (whew... was thinking engine was burning).
I ask her if it overheated, and of course she didn't think to look. I ask her if any lights came on and she said she didn't notice any. So I tell her next time she drives it to look at the temp guage and look for any lights. I also told her if it was overheating to pull over and let it cool down before driving it back.
So the next day she comes in the house saying that it is smoking again and that it overheated and the radiator light came on. (of course she drove it home while it was overheating

)
No coolant in the resivoer, so I open the radiator and dont' see any coolant in there. I check the oil for tell tail head gasket milk oil and the oil looks fine (thank God).
I look at the hoses for visable cracks and don't see any, of course there is coolant everywhere so it is hard to tell where it was comming from. My GUESS based on the splatter locations is that the cap blew (coolant all over top of radiator, under the hood, and pooled below the radiator).
Two other interesting things... the heater is blowing cold air (i assume this is because the heater core has no coolant) and the radiator fans do not come on.
I bought a new cap, a new thermostat, and rented a pressure tester. Its too cold out right now to mess with it, but thursday it is suppose to get up into the 60's...
Main question I have after all that rambling is this...
If i replace the cap and the thermostat and that does not fix it, AND the pressure tester indicates that I have a seal... what should my next step be? I will probably only have one semi-warm day to mess with this so Im looking for suggestions ahead of time.
