How to replace the thermostat housin, is it a difficult job, do the intake manifold have to be removed to do that job? What amount of time do you think it should take for the repair?


Currently I am struggling financially and I am unable to make a contribution. Your help is greatly appreciated. Thanks, Mr. Bell
