• Q: How to replace the Coolant Reservoir (LP1, LY7) on 2005 Cadillac CTS?

  A: Drain all coolant from the vehicle to start the Coolant Reservoir (LP1, LY7) replacement process. Begin by draining coolant and then remove clutch master cylinder reservoir bolts on cars with manual transmissions before moving the reservoir aside. Install j 38185 hose clamp pliers (J 38185) to detach the Coolant Reservoir inlet hose clamp before disconnecting the hose. Follow the same hose outlet procedure for the Coolant Reservoir. Separate the master cylinder from the Brake Booster by removing each nut so you can reposition the cylinder gently aside. First remove the two bolts securing the Coolant Reservoir and the bolt securing the Coolant Reservoir nut before you gently lift the air inlet grille panel to remove the device. After disconnecting the low coolant sensor's electrical connection you can proceed to remove the Coolant Reservoir. The installation process begins with plugging in the low coolant sensor electrical connection and installing the Coolant Reservoir which must have its tab facing behind the air inlet grille screen. Use the j 38185 to position the inlet grille aside before connecting the Coolant Reservoir outlet hose through its clamp installation. Fasten the Coolant Reservoir installing nut to 9 nm (80 inch lbs.) specifications. Use j 38185 to position the clamp which will secure the Coolant Reservoir inlet hose. Affix the two Coolant Reservoir bolts while tightening them to 9 nm torque (80 inch lbs). Screw in place the vacuum booster to the master cylinder before tightening the nuts to 25 nm (18 ft. Lbs.). After filling the cooling system personnel should install the clutch master cylinder reservoir to its bracket and bolt down the clutch master cylinder reservoir using 50 nm (37 ft. Lbs.) of torque.
