Question about 1997 Toyota Avalon

1 Answer

I've got a 97 Avalon XLS and the h20 overflow tank is bubbling. The temp gauge gets a little over halfway hot. In the winter it seemed like the heater never really got that hot. Now I turned off the a/c while car is running in garage and let it run for about 10 minutes. The overflow tank started to fill but the fans never come on. When the a/c is on the fans are on. I am wondering if I have two offsetting problems the thermostat being stuck open therefore little heat in the winter and the fans not coming on in the summer causing bubbling in the overflow. Where is the thermostat and the fan switch located?

The fan switch , should be a relay on the firewall, the themostat is on the driver side, just follow the top radiator hose

My 2004 Toyota Avalon xls driver side digital thermostat will not go from cold to hot when press up on the temp button... My passenger side works just fine I can adjust the temp all the way from 85 to 60...


It truly sounds as if the temp control panel has failed. Could be a contact in the temp control button. I am basing this on the fact that everything else is working correctly. You can usally find an inexpensive one through Car-Part.com or Ebay.

2003 Toyota Avalon xls model all lights and dials on instrument panel go off and engine stops when I go over bumps. I wait 2 minutes and car starts up again and runs fine until I go over bumps again.


The very first thing I would check would be if the battery cables are clean and tight. After that I'd lean towards a bad ignition switch. Do you have a ton of keys on your keyring? wiggle your key while its on to see if you can recreate the problem.

My 2000 chrysler voyager radiator fluid bubbles in radiator overflow tank evn when cold nd when turning over. I just had head gasket replaced whats going on


I suspect a crack in the head or block. The cooling system is suppose to be closed so any air has to be coming from somewhere - if the head gasket is good then the air is likely to be coming from a crack. A pressure test will confirm if your system is not air tight. That is if you are seeing bubbles in the radiator water if you just mean you are losing water through the overflow then it might just be the radiator cap needs replacing as it is not sealing the system when it gets hot.

2004 dodge stratus R/T with 2.7 heater blows cold air and it has coolant and new thermostat and the overflow boils over without the temp gauge being above halfway. how do you fix that?


Sorry to say but i have had plenty of experience with dodge vehicles and have ran into this problem before.....its your head gasket sucking air...(hence the bubbles in your overflow tank isnt from being hot....its the air escaping from your engine)......Plus the posiblility of your heater core being clogged....

Air bubble in coolant.


Replace the thermostat. That is the only cause of the bubbles.

If the water is flowing into the overflow tank then it is probably running a little hot. It is normal for a little bit to flow into if as the water heats and expands but there shouldn't be enough to overflow the tank. Have you tried changing the thermostat? If the thermostat isn't opening properly this will have all the effect in the world on how hot your engine runs.

My 91 Chevy s 10 Blazer over heats in addition to check gauges light coming on what could be the problem?


There are 4 things you want to check in this order.
1. Make sure your fluid level is up to specifications.
2. Make sure the fluid is travelling through the radiator freely(water pump).
3. Make sure your thermostat is opening. This requires a great deal of caution, leave the radiator cap open (if it has one) and run the engine until the top radiator hose gets hot, If you have no radiator cap, watch for water rising or dropping in the overflow tank.Also watch for bubbles within the overflow or radiator.Also put all temp controls on high on the climate control center and feel for hot air once the engine reaches operating temperature(185-200 degrees). If you don't get heat within the regular time slot of 10-15 minutes you will need a new thermostat.
4. If you discover a large amount of bubbles within the radiator or the overflow tank than you've got a headgasket situation and should not drive the vehicle until necessary repairs are made. Thank you, Dana

first determine if the car is actualy getting hot.dont trust the gauge or fan for these are controled by a temp sensor, if the sensor went bad it will tell you its hot. the other thing it might be is a air bubble trapped in the system
