No colant useage in Wife's Toyota ????

It is really odd for a coolant reservoir to never need topping off.
Especially with those miles and years on the vehicle.
Plain old evaporation wold account for some loss, even if there was nothing wrong.

Why i'm concerned is that the fluid level in the reservoir remains the same wether the engine is cold or hot and there is no bubbles or froth in the liquid like its working through the engine , it just sits there flat. But i will take your advice and open up the radiator and look inside to see what the level looks like inside.


I think the reservoir should move up to the hot mark or increase some if your radiator was actually full. I'm betting you are a little low under the pressure cap in the radiator. did you take it off yet and check it?

Thanks again guys, Yes i opened up the radiator and look in , the fluid looks nice and clean, it is not filled all the way up to the spout the way i like it but it is still above the veins, i am going to change it this weekend being that it has 120,000 miles on it.

Happy to know that its normal on these modern cars, the cars we owned in the past -91 Plymouth sundance, 92 Lincoln continental and 87 GMC Safari all used up some coolant , not much but i would have to top up like once a month.
Thanks, Tundraz

The fluid should be up to the top -all the way.
MAybe your cap is bad, or the line to the reservoir.

Thanks, i'll check the line to the fluid tank and the cap also, maybe i'll just change the cap.
