in the block...
The engine block coolant drain plug on 4.3 liter Chevy Blazer is located on the bottom of the engine, near the oil filter. It allows coolant to be completely drained from the block during maintenance.
The 1994 Lincoln Town Car 4.6 liter engine coolant drain plugs can be found on each side of the engine block. There will be a total of four engine coolant drain plugs.
there is no drain plug in the actual block there is a plug in the lower drivers side of the radiator. to flush the coolant out of the block just, run the motor with the heater on with a water hose in the rad filller until fluid coming out is clear.
Look for the radiator drain it should be on the side of the radiator facing the engine next to the fan.
There are actually three coolant drain plugs on the 2001 Tundra. Speaking of a 4.7 liter engine, there is one drain plug at the bottom of the driver's side of the radiator. The skid plate/splash shield need to be removed in order to access this. It is a plastic butterfly type and should be easily removed by hand or with the aid of pliers. The other two are located on the driver's side of the engine block. This truck takes over 12 quarts of coolant so these two drain plugs need to be opened in order to completely empty the coolant from the system.
It is located near the front of the motor, near the thermostat, screwed into the block.
The engine coolant capacity for the 4.0 liter - OHV engine is ( 12 U.S. quarts ) and for the 4.0 liter - SOHC engine ( 14 U.S. quarts )
Check the engine coolant... Is it full? yes coolant level is full
To bleed the coolant in a 1995 Dodge intrepid locate the drain plug on the underside of the radiator, un plug it and pour new coolant in the system. Close the plug and while the engine is running find the coolant pressure valve and loosen it to relieve pressure. When bubbles stop forming there is no longer air in the system.
I just popped the lower radiator hose off - after the big gushing of some really *ugly* fluids, I put it back on and refilled.
