new o-rings coated with A/C PAG oil
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, just replace the radiator. The other one (in the front) is the condenser for the a/c system.
When replacing the housing O-ring in a shallow well pump, using a sealant is typically not necessary if the O-ring is in good condition and properly seated. The O-ring is designed to create a watertight seal on its own. However, if the O-ring is damaged or if there are grooves in the housing, a light application of a compatible sealant may help ensure a secure fit. Always refer to the manufacturer's guidelines for the best practices specific to your pump model.
no u dont need to use sealant u should get a gasket
Yes, however you will need to provide more details as to what you are doing with the condenser.
The Chevrolet water pump bolts do need a sealant. Thread tape can be used on the bolts in the place of a sealant.
