SOURCE: intake manifold sealant repair now leaking maybe oil? coolant b4

You need to remove the thermostat housing again. Then you will have to extract the bolts you broke off. You will need to drill and tap them so you can use an easy out to remove the broken bolts from the threads. Then you can clean up both mating surfaces and replace the gasket and the thermostat. Check to make sure you did not crack the thermostat housing or you may have another leak when finished. They are usually aluminum and break easily if too much pressure is applied or they are corroded and weak.

I need to find the truck termostat, where is it?


The thermostat is located in the front of the intake manifold under the thermostat housing, and follow the upper radiator hose over to where it connects to the engine on the intake manifold and that will be the thermostsat housing. remove the upper radiator hose from the thermostsat housing and remove the ground wire if there is one attaced to one of the two thermostat housing studs, and then remove the two studs/bolts from the thermostat housing and then remove the thermostat from the intake manifold. Be sure to replace the thermostat correctly and here is an image to help assist you.
