I have a 2005 Focus, sedan. I think is LX, sedan. The engine is seized. Has anybody tried any of the special liquids that you put into the engine and makes it work? I am afraid it is an online scam.
You need to say what happened to be able to help.
Did it run out of oil? and driven until it locked up?
Did in get hydrolocked? (water into the intake)
Did it get left outdoors with the hood open and no plugs in engine for a few years?
Did it get over revvved by being at 80mph on the freeway and the guy managed to get it into first gear and then let out the clutch just to see what would happen?
Is just the starter frozen? and lock to the flywheel?
Plenty more possibilities..
Added: in general, take out the sparkplugs and try to turn over the motor.
Try to rotate the motor with a wrench on the pully off the crank. (after taking out the sparkplugs.)
What do the sparkplugs look like OK, oily, black, really white. any broken?
Drain the oil and see what it looks like? What/how much comes out? remember to refill the oil!
