Have a 2019 Ford Explorer Sport. I got the ShopPro Universal Yellow Antifreeze and Coolant Ready-To-Use 50/50 Auto zone one and i poured it all in , I noticed the car label was asking for the orange coolant , should i be worried ? can I mix these 2 or do i have to flush it out please help

[@InsaneOil]

The orange coolant is typically “long life” coolant… however there generally is no issues with mixing coolants.

On that cari would check the water pump

What does it mean if you have oily sludge in a cylinder head and what should I do thanks?

[@InsaneOil]

Could mean a number of things including using poor quality oil, ignoring oil service intervals, coolant contamination, moisture contamination, or even idling the engine for prolonged time periods frequently.

@@InsaneOil ok it's a vehicle I bought not running and have been fixing up. I think it could be tube seals and or valve cover gasket. Thanks

@@user-pu5jd3ez3d In general it is fine to mix coolants, especially if you are running low. Just know that mixing coolants doesn't give you the best performance possible.
