Always refer to the service manual for your vehicle and consult with a professional mechanic if you are uncertain about any part of the process. Remember that this is a general outline, and your specific vehicle may require additional or different steps. Reconnect the negative battery cable, and start the engine to verify the timing chain replacement was successful. Bleed any air from the system as necessary. Refill the cooling system:Ĭlose the radiator drain valve and refill the cooling system with the appropriate coolant. Reinstall any accessories and components removed earlier in the process, such as the radiator, fan, fan shroud, drive belts, and air intake assembly. Use a harmonic balancer installer to reinstall the harmonic balancer onto the crankshaft. Torque the bolts to the specified values in your service manual. Reinstall the timing cover:Īpply a new gasket or gasket maker, and reinstall the timing cover. Ensure that the timing marks are properly aligned and the chains are correctly tensioned. Install the new timing chains:Īlign the timing marks on the camshaft and crankshaft sprockets, and install the new timing chains. Replace any damaged components, and install new timing chain tensioners and guides. Inspect the camshaft and crankshaft sprockets for wear or damage.
