radiator flush on a system that does not have radiator cap?

Yeah. I agree that the word dry doesn't make sense. However, if you had no cap on the bottle, I would recommend flushing the coolant out and putting a cap on it. You don't want contamination in the coolant which will happen if the bottle is not covered.

Here is a guide on coolant service that will help explain this:

It is good that you don't have an issue right now but I would not wait until you have an issue to take care of this. Let me know what questions you have. Thanks

I have a cap on my coolant reservoir. My car is a 2002 Ford Escape so it has a pressurized system that does not have a radiator cap at all. I am not missing anything, my car simply does not have it. My coolant reservoir looks clean and is full.

Hello, I'm Danny.

It sounds like they might just be trying to up sell you on a coolant flush. Places do that to make more money off you. If the level is fine and the car is running good not overheating then I wouldn't worry about it. If you want to test the condition of the coolant you can go to any auto parts store and buy coolant test strips. You just dip them into the coolant and it will tell you the condition of the coolant as to being good or dirty. Just wanted to add my 2 cents. Hope this helps and thanks again for using 2CarPros.
