Town & Country V6-3.8L VIN L (2006)
There is no need to remove the radiator cap at any time except for the following purposes:
1. Check and adjust coolant freeze point.
2. Refill system with new coolant.
3. Conducting service procedures.
4. Checking for vacuum leaks.
WARNING: If vehicle has been run recently, wait 15 minutes before removing cap. Then place a shop towel over the cap and without
pushing down rotate counterclockwise to the first stop. Allow fluids to escape through the overflow tube and when the system stops pushing
coolant and steam into the CRS tank and pressure drops push down and remove the cap completely. Squeezing the radiator inlet hose with a
shop towel (to check pressure) before and after turning to the first stop is recommended.
INSPECTION
Fig. 35 Cooling System Pressure Cap
Hold the cap in your hand, top side up (Fig. 35). The vent valve at the bottom of the cap should open. If the rubber gasket has swollen, preventing the
valve from opening, replace the cap.
Hold the cleaned cap in your hand, upside down. If any light can be seen between vent valve and the rubber gasket, replace the cap. Do not use a
replacement cap that has a spring to hold the vent shut.
A replacement cap must be of the type designed for coolant reserve systems. This design ensures coolant return to the radiator.
