Where are the freeze plugs on a 1993 Buick Lesabre?
In the sides and rear of the block.
Does a 1993 Buick Lesabre have a fuse for the horn Or could there be another reason that it does not work?
It should be located on the intake manifold by the distibutorless ignition module. On my 92 Lesabre it is located near the plugs at the back of the motor. On my 94 LeSabre it is located on the front/driver's side of the engine. There is a 4-wire connector on the top and it is mounted by two bolts on a flange. About 2" in diameter, 4" high.
On a 1993 Buick LeSabre why is it sometimes hard to start and missing a spark signal how can you fix this?
The belt tensioner on a 1993 Buick LeSabre is located below and slightly to the left of the alternator if you are facing the passenger side of the car **Note there should be a diagram somewhere in the engine compartment, if not drawing one before removing the alternator belt for any reason will save you a major headache later on. GOOD LUCK
