• Q: How to replace the RH secondary camshaft timing chain on 2008 Cadillac XLR?

  A: To replace the right Timing Chain, one needs first to remove the Oil Pump. With the help of the crankshaft socket (J 39946), turn the crankshaft to align the primary timing gear marks. Then disassemble the right Camshaft position actuator housing without separating the actuator solenoids. Mount the Camshaft holding tool (EN 46328) on the bank 1 (right) cam shafts. Services and tighten the lower right Timing Chain Tensioner bolt to 28 foot pounds and remove the tensioner. Closeoperation wrench on the hex cast into the Camshaft so that it can't rotate while removing the bank 1 (right) exhaust Camshaft position oil control valve (slide the right exhaust Camshaft position actuator off and remove the Timing Chain from the actuator teeth). Repeat the procedure for the continental intake Camshaft position oil control valve and actuator. (Bank 1 or right). Take out the right Timing Chain from the engine and then clean and check the Camshaft timing drive components. While installing the new Timing Chain, join the three black links with the correct points of timing on the bank 1 exhaust and intake actuators, as well as intermediate sprocket. Loosely insert the oil control valves to secure the actuators and tighten them to 120nm (89lb ft) using an open-end wrench not to allow the Camshaft rotation. Install the correct Timing Chain Tensioner, pull out the Camshaft holding tool (EN 46328), and plug back in the right Camshaft position actuator housing and Oil Pump.
