Solstice L4-2.0L Turbo (2008)
4. Using a non-silicon based tire lubricant, lightly coat the check valve (P/N 20876185) and insert it in to the engine return hose (1) 15 mm (0.5 in) in
the hose with the tapered end pointing toward the nipple that is on the engine (1).
5. Press the hose on to the nipple and seat the hose to the base of the fitting (1). This will push the check valve further in to the hose, resulting in a
slight bulge in the hose in the middle of the bend. The valve should not be pushed in the hose to the point that it is in the horizontal position. A
check valve in the horizontal position will not function properly.
6. Remove the hose. Install the hose clamp on the hose and reinstall the hose.
Important
The tapered end of the check valve must face the nipple on the radiator. A check valve in the horizontal position will not function
properly.
7. Remove the coolant return hose from the radiator. Carefully remove the clamp from the hose and set aside - the clamp will be reused in the final
step of installing the hose.
Notice
When performing the next step it is important that you press on the line in a straight motion. Excessive side load may result in a broken radiator
nipple.
8. Using a non-silicon based tire lubricant, lightly coat the check valve (P/N 20876185) and insert it in to the radiator hose return line 15 mm (0.5 in)
in the hose with the tapered end pointing toward the radiator nipple. Press the hose on to the nipple and seat the hose to the base of the fitting. This
will push the check valve further in to the hose resulting in a slight bulge in the hose.
9. Remove the hose. Install the hose clamp on the hose and reinstall the hose on the radiator return.
10. Add coolant to the "Full Cold" line of the bottle. To purge any air from the system, use the vac-n-fill process per SI.
11. Inspect the cooling system for leaks.
12. Rinse away any excess coolant from the engine and the engine compartment.
