it on top of the thermostat
On a Lincoln LS : The engine coolant reservoir is located in the engine compartment , on the drivers side , near the firewall ( I believe it has a thread on cap , which would be the pressure cap / radiator cap )
On a 2005 Lincoln LS : ( the thread on cap on your engine coolant reservoir is the pressure cap / radiator cap ) * the engine coolant reservoir is on the drivers side of the engine compartment , by the firewall
On a 2002 Lincoln LS : The engine coolant reservoir is in the engine compartment , on the drivers side of the engine compartment , next to the firewall . According to a drawing I was looking at there is some kind of trim piece over the top of it , but the trim piece has a hole in it to gain access to the engine coolant reservoir cap
On a 2000 Lincoln LS : The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap * the engine coolant reservoir is in the engine compartment , on the drivers side of the engine compartment , next to the firewall , you can see the cap through a hole in the " trim "
The thread on cap for your engine coolant reservoir is the pressure cap / radiator cap ( the engine coolant reservoir is located on the drivers side of the engine compartment , near the firewall )
the specifications should be on the oil fill cap sorry this is the best i can do
The engine oil filler cap on a 2000 Lincoln Ls is : ( V6 ) drivers side of engine , near the front of the engine , on the top of the engine cover ( V8 ) drivers side of engine , near the rear of the engine , on an extension tube
On a 2002 Lincoln LS : The degas bottle ( engine coolant reservoir with the pressure cap / radiator cap screwed on the top ) is located in the engine compartment , near the firewall , on the drivers side of the engine compartment ( you will see the " cap " through a hole in a piece of " trim "
Drain the old stuff out from the plug on the oil pan (replace the filter while you're under there). Put the new stuff into the fill cap on the engine.
Your moms size
On a 2002 Lincoln LS : The engine coolant reservoir has the pressure cap / radiator cap screwed on top of it , so it is called a degas bottle * it is located in the engine compartment , on the drivers side , near the firewall ( there is a hole through the " trim " to gain access to the cap )
I'm not a mechanic / technician but I believe the degas bottle is an engine coolant reservoir that has the pressure cap / radiator cap screwed on top ( instead of having a radiator cap on the radiator ) In the case of a Lincoln LS : It is in the engine compartment , on the drivers side of the engine compartment , near the firewall ( you will see a hole in the " trim " that allows you to see the reservoir " cap "
