Can I let my car hot soak overnight with Sea Foam Spray? [SOLVED]
I have a chrysler 300 2018 v6 and they used to have a similiar product. However, when I used that after spraying the can I would let sit overnight or longer. And then give it a good run. Your instructions says 10min then give it a good run. Can I let it sit overnight before going for a drive.
Great question, Ed. With Sea Foam Spray, I would not recommend letting it soak overnight. For an upper engine cleaning, a shorter hot soak of about 10-15 minutes works better because the heat in the engine helps with the cleaning process.
After applying the Sea Foam Spray, shut the engine off and let it sit for about 10-15 minutes, then restart it and drive normally. You don’t want the engine to cool completely with the Sea Foam still in the combustion chambers, as that can increase the chance of fouling the spark plugs.
