Re: Need help diagnosing cooling issue
As always with any engine I own I use 50/50 green antifreeze. Running plain water will cause increased corrosion rates and will not cool as efficiently. If you have a thermostatic fan clutch check it for correct operation, check the thermostat in the intake to see if it's stuck closed, check hose clamps at all connections, check freeze plugs for a pin hole leak, you can perform a compression test to rule out a blown head gasket, carefully inspect the intake manifold especially on the the back side for wetness. Check around the timing cover and water pump gaskets and the weep hole on the water pump. Also if you have oil leaks you can spot a water leak by looking for a light colored goo. When water mixes with oil it makes a coa coa milk goo.
