Why your f150 is running hot after you put stop leak in?

If your F-150 is running hot after adding stop leak, it could be due to a few reasons. Stop leak products can sometimes clog the cooling system, obstructing coolant flow and causing overheating. Additionally, if the stop leak was added to a system with existing issues, such as a failing water pump or a damaged radiator, those problems may be exacerbated. It's advisable to flush the cooling system and check for any underlying issues to prevent further damage.
