Running Hot

[keweenaw]

Have a 2015 f3s that was a little low on coolant this early spring added the orange Gm dexcool and now is overheating mainly so if stopped for any length of time seems alright when moving at speed but definitely heats up fast at a stop light etc Thoughts?

More info please. Does the gauge go up? Does it overflow coolant? Do the fans come on? Have you cleaned the radiators? Four screws and the grill comes off and you can see the radiators. (they tend to clog with debris).

Cleaned the radiators last fall the bars go up at stops or slow speeds fans do come on and it’s actually cool here 50 no overflow I did buy the extended warranty at least

Did you use a pressure washer? if so you may have closed off some of the vanes.

To start with make sure you have no coolant leaks.If that's good I would drain and flush the coolant system not good to mix coolants.
