Coolant temp low indicator light/Coolant temp high warning light?

1905 Views 2 Replies 3 Participants Last post by  slothman
i have just purchased a 2018 Subaru forester and I have issue with the Coolant temperature low indicator light/Coolant temperature high warning light. Saturday, I parked the Subaru in my garage before supper at a temperature of 4’C. The next day at 14’C, it took over 2 songs on the radio, before the blue light indicator went out, and I could drive the vehicle (.BLUE indicates insufficient warming up of the engine).

I am wondering if this amount of time is normal to warm up these engines/coolant?

If so, I am wondering the timeframe for the sufficient warming of the coolant on a late February evening when the temperature is around -10’C.

Thanks

Drive your car, you'll find the blue light will extinguish a lot quicker.

You don't have to wait for the blue light to go out before driving off. Just give the engine a couple of seconds to get the oil fully circulating - 0w20 oil is only slightly thicker than water, plus Subaru use higher pressure oil pumps than other brands so there is little delay in getting oil to every part of the motor - and then drive off. Just don't floor the accelerator, or red-line the engine until it is fully warm. This is actually better for the engine than letting it idle and also gets other drive train components up to temperature quicker too.
