I have a '94 Saturn SW2 and I want to get an engine block heater or somthing like it because I live in Western MN and I don't have a garage. I have searched all over the web, but I cannot find out what block heater will work with my model nor have I found a store to purchase one from. Any help would be appreciated.

If you live in a cold environment, the engine oil will get thick and your truck will be hard to start. Look into installing a block heater (if you don't already have one). The block heater will heat the engine coolant and ultimately keep the block warmer.
Block heaters are usually on the drivers side. They are inserted in the block where a freeze plug usually goes. You'll have to look on the bottom of the engine to see it. It will be it the front or the rear of the engine as the center plug is hidden under a mount.
IF ENGINE RUNS AT RIGHT TEMP SOUNDS LIKE YOU MAY HAVE AIR BLOCK, OR BLOCKED HEATER MATRIX, CHECK FIRST CHECK THE HEIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN COULD BE AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS (TWO PIPES GOING FROM ENGINE BAY TO INSIDE OF CAR, AND FLUSH OUT WITH HOSE TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP, YOU CAN BUY A COOLENT FLUSH SOLUTION TO CLEAN THE SYSTYM OUT
The most likely problem is a stuck heater switch. follow the heater hoses from the firewall to the engine block, somewhere along those lines will be a switch that allows the warm coolant to pass through the heater core. place your hand on both sides of the switch with the car warmed up, if the side towards the block is warm and the side towards the heater core cool then replace the switch.
Thje only block heaters I know of are the ones installed by the customers. First thing you would see is an electrical household cord hanging under the engine somewhere. The heater is installed where a soft plugs is used on an engine. This would be in the side of an engine block.
If you don't have one have a garage put one in. You don't want to take a chance this winter and not have it done right.
