Hello,
My toyota overheats. I have had the waterpump replaced twice, the head gaskets were replaced under a recall several years ago. Also, all hoses and themostat were checked. The electric fan comes on when started and then stops after about a minute or so. The temp gage climbs to the half way point quickly. It is most notiiceable in weather warmer than 60 degrees. Any suggestions would be welcome.

Thank You.

Does the temp gauge go all the way to the right? Or does it quickly climb to halfway and stop?

I know this may sound trivial but I have to know.

The temp gage goes to the half way point in about 6 to 10 minutes, depending on the outside temperature.

Are you loosing any coolant? If not, I think the system is operating normally.

I went out and timed the rise of the temp gage. It took about 4 mins. To get to half way. It then stops. In weather that is warmer though, after about a 10 min. Drive it will start to creep up the scale. I have always turned it off before it got into the red range. I also checked to see if both hoses to the radiator were getting hot, and they were. I did notice that the electric fan in front of the radiator will come on for about 3 mins. Then stop. One auto mechanic told me to turn on the air conditioning and the electric fan should come on. I checked that and it did not. I have been told that it should "cycle" and I have not noticed that. Of course it is about 26 degrees outside right now and does not seem to over heat.

Well, the fact that it still over heats in hotter weather? Any help would be appreciated.

Any Ideas?

So in the warmer months, the temp gauge will go all the way to the right? And when it overheats, does steam come from under the hood? If not, I think the gauge may be a little irratic.
