when replacing a frost plug u can use a sealant but only use silicone u dont realy need it and yes u have to clean the area good
You need the sealant on the ends where the supplied gaskets don't cover fully.
Thermostats in most vehicles have seals and gaskets that are designed so you do not need any aditional sealant.
yes because it make the ac longlife
YES! I just spent over $1500 replacing the alternator, condenser, condenser fan and alternator fan due to corrosion because the panel was missing.
You do not need to add a sealant to the gasket. Just make sure you torque the bolts to factory specs.
No you do not.
no u dont need to use sealant u should get a gasket
The Chevrolet water pump bolts do need a sealant. Thread tape can be used on the bolts in the place of a sealant.
No, just replace the radiator. The other one (in the front) is the condenser for the a/c system.
You do not need any special crankshaft installer, when replacing the head gasket. The crankshaft and the head gasket are on opposite ants of the engine.
no gasket sealant needed. Just original gasket is fine.
