2005 Chevrolet Impala Thermostat Parts Questions & Experts Answers

• Q: How to replace the thermostat on a 3.8L engine on 2005 Chevrolet Impala?

  A: Begin Thermostat replacement on a 3.8l engine by taking off the fuel injector sight shield and lowering the cooling system's fluid level. The hose clamp pliers (J 38185) should be used to relocate the hose clamp from the water outlet housing before removing the radiator inlet hose from this housing. You should first separate the water outlet housing bolt and the stud before taking out the water outlet housing and the gasket. To set up Thermostat installation you should first remove and inspect the mating surfaces of the water outlet housing. Proceed with installation by first installing the new Thermostat followed by gasket placement then mounting the water outlet housing. Secure the water outlet housing bolts alongside the studs into place until they reach 27 nm (20 ft. Lbs.) torque. When ready use hose clamp pliers (J 38185) to secure the radiator inlet hose at the water outlet housing. When finished fill the cooling system while you replace the fuel injector sight shield.
