Engine Coolant Warning Light

Recommended Posts

How long after switching the engine on should it take for the coolant warning light to go off?

Mine takes a few minutes.

Should be within 7 -10 seconds.

You have checked the coolant level? Could be low..

It's not below the min mark.

I'm not sure how often you should be topping it up in a Yaris.

It was only serviced last month.

Are you meaning the 'engine cool' light? Is the light green? This light is a coolant temperature light and takes about 5 mins to go out, especially when it is cold outside.

I didn't know there was a coolant warning light?

I wouldn't trust it anyway I always visually check

My engine coolant temp gauge take a good 5 mins in this weather

A couple of mins (if that) in summer

On the Mk1's the coolant temp light is blue when first started to let you know the engine is cold and obviously hard throttle use is to be avoided. On these cold mornings mine takes about 5mins to warm up fully.

When the light goes out, the engine is warm and up to normal running temperature.

If the light ever glows red, then it's a sign of overheating.

That is quite correct Raeman,

I personally would prefer a gauge as then you can keep an eye on it.

With the light, if it comes on red you must stop,there is no earlier warning that the temp is rising

with a needle you can see the needle rising towards the hot end.

Why don't all manafactures put a gauge in as i think it is one of the most important gadgets instead of the cheap option like that in the Yaris?
