I have a 93 Camry wagon with the 3VZ-F3 v6. It overheats

Customer Question

Hello.
I have a 93 Camry wagon with the 3VZ-F3 v6.
It overheats while driving or at an idle.
I have replaced the radiator caps. The thermostat has been changed twice. The fan comes on when the car is started, and the high speed comes on when I turn on the ac, which blows very cold.
Once the car is at operating temp ( slightly below the half way mark ), it is fine for about ten minutes, then the temp slowly begins to climb. With the temp now at 3/4 and climbing I notice when I increase the rpms the temp begins to drop to just above the half way mark.
Coolant level is good, there is no white smoke from the exhaust, there is no bubbling from under the radiator cap while the car is running.
I have no experience with Toyotas, please help!

I would like to know if you have looked into the radiator as it is running?

Expert:  David Gieswein replied 6 months ago.

I would recommend doing it when the car isn't really hot. Say like when you just started up, cold engine. Then keep the cap off and continue watching the coolant.

Expert:  David Gieswein replied 6 months ago.

You should see a some type of flow of the coolant. If it is just sitting there, then the water pump could have gone out.

Expert:  David Gieswein replied 6 months ago.

I had a Dakota one time that ate my lunch. I replaced the radiator cap, replaced the radiator, and checked fan operation. Still the truck would overheat. Finally I took the waterpump off and found that the impeller was freewheeling.

Customer: replied 6 months ago.
Is it an obvious flow?
Cause I looked at that and I couldn't be 100 percent there was flow.
Also, what is the best way to check that the radiator isn't plugged?
Expert:  David Gieswein replied 6 months ago.

Yes, there should be obvious flow. You can even try having someone rev the engine and watch it to see if the flow changes intensity.

The best way to check a radiator is pull it and take it to a local radiator shop. There they can test and clean it.

Customer: replied 6 months ago.
Alright. I will check the flow tomorrow and let you know what I find.
Thanks!
Expert:  David Gieswein replied 6 months ago.

No problem. Have a good evening

Expert:  David Gieswein replied 6 months ago.

Have you had a chance to look at the flow again?

Expert:  David Gieswein replied 5 months ago.

Just checking on your progress. Have you found anything out yet? Do you still need help? If you no longer need help, please rate me!

Customer: replied 5 months ago.
Haven't checked that flow yet. I recently had shoulder surgery and some days are slow going with physical therapy and then life! lol.
I will check it tomorrow

Sounds good, no rush. Hope you feel better.
