94 Camry Overheating Help Please!!!?
Hello all,
I’ve come here for advice. Today my camry started overheating. Upon inspection I see coolant boiling over from my coolant resivor. I visibly see no coolant leak. I have to wait 15 minutes to let the engine cool down and then drive 3 miles and then cool down again. So it took me 1 and 1/2 hour for me to get home today even tho I live 30mins away. When I got home I opened up the radiator cap and coolant gushed everywhere. The coolant color is brown, which I know is not good. So I added new coolant in. I’m gonna see tomorrow morning if it still overheats with the new coolant. Also, I noticed both of my radiator fans are not automatically turning on.
Any ideas or suggestions would be greatly appreciated. Thanks all.

Could be three things, judging from your description. First of all, is your check engine light on? If so, check the Temperature Sensor, as this also controls your fans. Otherwise, your thermostat is most likely the culprit. Another thing you can do is, with the car running and cool, open the radiator cap and look in, if there are bubbles coming up in the coolant, you have compression gases entering your cooling system, caused by a blown head gasket.
Okay there could be a few things. Try turning on your air conditioning and see if either of your fans come on at least one should because it’s the condenser fan. If it doesn’t then you may have a bad fuse, fan motor, temp sensor. Also if there was no coolant in the motor the fans wouldn’t come on because they have to be submersed in liquid to read, steam won’t do it. To fill the coolant fill the radiator, then leaving the cap off start the vehicle, turn your heater on, then go continue filling the radiator until the car is up to normal temperature, then replace the cap before shutting the car off. Filling it this way will get the air out of the system. You may want to put a drain pan under the car where you fill the radiator. If it overheats while doing this it’s a possibility that it’s a blown head gasket. And sorry to say that’s gonna be money.
First I would say that you may want to change the thermostat, you can go to the autoparts store and they usually have helpfull employees that will be able to look up which one you need. Second I would say that you need to flush your radiator and add new coolant, the coolant that is in there is way old. If this doesn’t fix the problem your radiator may need to be rodded out, which is cheaper than getting a new one all together. As for the fans, I am not familiar with camrys, but I would ask the people at the autoparts store. Also for the mean time if you begin to overheat immediately turn on your heaters full blast it may be uncomfortable but it will bring the temp down. Also you may want to keep them on to help prevent overheating.
Thermostat
Drain all the coolant out and run water in it for a few days (since its over 32 degrees) so you can get all the crap out of your coolant system.
Then repeat that after 3 days.
Your problem is either a bad temperature sensor, which does not kick the fans on when it gets hot.
OR
You probably have a bad thermostat.
If you remove the thermostat and do not have money for a new one right now,you will not have heat is all but they are cheap so I would recommend you replace it and a new gasket for the “Neck” which is the “coolant intake”
DO NOT RUN it when it gets too hot you will burn up the motor.
(keep a close eye on your temp gage)
Make sure it is RUNNING (once it cools enough to get the radiator cap off) and you want to add more coolant so you don’t crack the engine block.
Your problem lies with the radiator fans-have them fixed asap. No amount of coolant will cool your car if those fans do not work at all.
If youhaven’t ruined the head or the head gasket’take the T.stat out run some rad. flush(prestone,etc:), follow the instructions on the bottle and watch the TEMP. gauge afterwards under normal driving cond..If it does ok , replace the thermostat! Turn the A/C on to see if the fans are running(they should be!) . If not ,check coolant temp.sens.(replace)(2),check relay with known one that works,or purchase one.The coolant flush should remove at least 50% or so of the rust in the rad. & engine.But you need to see , without rad. cap off, if coolant guisers out the rad, which means you for sure have a serious prob!!
