Thermostat Information
You will need to remove the thermostat as part of removing the intake manifolds in order to reach the oil cooler. We strongly recommend using this oppurtunity to replace the thermostat, but if you plan on re-using your existing thermostat please add the thermostat gasket to your cart, available as an add-on.
Coolant
The thermostat will need to be removed for this job, and the intake manifolds have coolant going through them, in addition to the oil cooler. Failed oil cooler seals may also lead to oil contamination in the coolant. Therefore it is recommended to drain the cooling system and refill with fresh coolant.
Injector Line Socket
Removing the intake manifolds requires removing the injector lines. The lines at the injector take a 17mm wrench, but there is not enough clearance to get a wrench around the line. Therefore, we stock and recommend getting the special 17mm injector line socket below to take off the lines without damaging the lines or injectors.
