★ Top Answer
The 2006 Toyota Sienna uses red 50/50 coolant, which can cause various engine issues. Problems such as a spark plug popping off, loose gaskets needing tightening, oil leaks that must be promptly fixed, and the risk of engine overheating leading to fires or even explosions may occur. Excessive oil consumption may necessitate more frequent oil changes. It is recommended to change the coolant every 60,000 miles, replace the air filter every 15,000 to 30,000 miles, and swap out standard spark plugs every 100,000 miles or copper spark plugs every 30,000 miles.
