Hey Scotty, big fan of your videos! Thanks for making everything so easy... Now to my question good sir. I've got a '07 Grand Cherokee Laredo 3.7L, noticed the coolant level was low recently so I bought some coolant (they gave me the wrong stuff) my car calls for HOAT and they gave me Dexcool, I realized it after it was too late. The reason the coolant was leaking is the water pump gasket is failing. So I have a water pump that needs to be replaced and I've heard if you mix Dexcool with other coolant types it can "gel" up pretty quickly, and the coolant that was in there before adding any was very rusty and corroded. I need to flush the system, I should do this before replacing the pump, correct? Also how long does it take for Dexcool and other coolant to "gel" up. Its been about a week since they were mixed. Thank you for your advice! Keep those videos coming!
