On most cars a gasket is required along with the RTV sealant. A new gasket should have come with the water pump. Ask the parts house where you purchased the part.
The head gasket itself is relatively cheap..around $20 at most but the labor involved with changing it would probably be at least $400 if done in a shop.
The oil filter gasket is built into the filter itself, so just by changing the filter, you always get the new gasket.
You do not "lube" the gasket with anything. If it is a flat paper gasket, you can use any shelac type sealer, but you don't have to as these will usually swell with contact with coolant and seal. If it is the kind that is a rubber ring around the thermostat itself, these require no sealant as pressure alone seal the housing to the motor.
Some head gaskets come with a coat of "Copper coat" sealant already on it. You can use copper coat on a head gasket safely. I prefer "Indian Head Shellac" myself. Just be sure to completely clean the heads first, and apply the sealant liberally. If you use too much, you can damage your engine by the sealant leaking into the engine itself.
more than likely it is the water pump gasket,it probably has a tear in it or just dry rotted from age and use or if it is leaking out of the water pump itself it is the seal inside the water pump itself if this is the case the water pump must be replaced if it is the gasket just replace the gasket ...
Sometimes yes, sometimes no. It depends on - A) what type of engine and B) what type of gasket. Older cars mainly used cork gaskets, so gasket sealant was a wise choice. New engines use rubber, some with metal bushings or spacers, so the typical "blue glue" as daddy used to call it isn't required.
Changing the gasket itself is simple.. drain the oil, unbolt the oil pan from the bottom of the engine, use some aerosol gasket remover and remove all traces of the old gasket, slap the new gasket on with some RTV, and reattach the oil pan to the engine block. Not a whole lot to it. The trouble lies in getting to it... on a lot of cars, you'll actually have to remove the engine from the engine compartment in order to do this.
It costs between 30-40 dollars for the head gasket itself.
To change the thermostat-- * drain the cooling system down to thermostat level (or lower) * remove the two (2) thermostat housing bolts, and the housing itself * remove old thermostat, discard gasket and clean both gasket sealing surfaces (pay attention to the orientation of the thermostat when you took it out; it only works one way) * install the new thermostat * place new gasket onto water box surface, over the thermostat, and center the thermostat in the opening of the intake manifold * apply gasket sealant, if necessary * place the housing over the gasket and thermostat, and torque bolts down to 250 in. lbs. * refill cooling system to compensate for lost coolant
no, because the wood isn't changing itself, you are changing the wood.
The gasket itself is about $100 bucks, but all the work that goes into removing parts to get to the head gasket to remove & replace it, and then put it back together is what runs you into the $1,000's if you take it to a dealer or mechanic.
it is located on the transmission itself
