Top 10 2000 Daewoo Leganza Questions & Answers

There is sooo many problems with the 1.8ltr engine (2001) ..for example the oil ports in the cylinder head casting are way too small.. this causes clogging and obvious lack of flow and then lack of power due to compression ratio going out the window.. I've re-built quite a wee number of these puppies.. including my wife's own car..so I heartily recommend the below..
1/ THOROUGHLY FLUSH EVERY LAST BIT OF GRIME, DEBRIS, LACQUERS & OIL OUT OF ENTIRE ENGINE..
2/CHANGE FILTER & REFILL WITH SEMI-SYNTHETIC 15/40 OIL..
3/ OIL AND FILTERS MUST BE CHANGED EVERY 3,000 TO 6,000MILES TO MAINTAIN ENGINE (IF NOT BORING OIL PORTS AND QUITE SUBSTANTIAL WORK & EXPENSE)

This should give immediate effect, but you may also consider the CRANK/FLYWHEEL SENSOR.. It's NOTORIOUS.. Along with the IGNITION COIL PACK.. CONSTANTLY CRACKING HIGH TENSION LEADS..Etc...
Hope this helps someone out there..

You remove air filter and other parts.
Then you remove head cover.
Then you unscrew and remove the head,
Clean a bit the block
Replace gasket.
Screw back the head
Follow head tourqe settings and screw orders on diagrams when mounting back the head.

The whole thing is not thst easy as it may seem, if you want to DIY you will need to buy the Haynes manual for your car. There you find a step by step procedure with pictures.

Here is a repair manual.

Also enquiry to Haynes.Haynes manuals are the best.

Here is how to replace head gasket on a Honda, with lots of pics, procedure is the same, torque values and screwing order are different. It is not a job for absolute beginners

It's part of the hazard/4way flasher switch assy.

Sounds like the park/brake shift interlock switch is bad.

Or

"An actuator solenoid and module assembly, located on the lower portion of the steering column, locks the shifter in Park whenever it receives a signal that the ignition switch is in the ON position. When the module receives a signal from the Brake On-Off (BOO) switch that indicates the brake pedal is depressed, it unlocks the shifter so that it can be shifted out of Park."

It says the most common failures in the system are the fuse and the BOO switch, and if they are fine, special tools are needed to diagnose.

To disable the system: Apply the parking brake, turn the ignition key to LOCK, then remove the key. Insert the key and turn it to OFF. Press the brake pedal. Shift to neutral, start the vehicle and select the desired gear.

SPEEDOMETER (SPEEDO DRIVE) IS USUALLY LOCATED IN GEARBOX NORMALLY SCREWED IN SMALL BOLT YOU WILL PROBABLY FIND IT AT REAR END OF GEARBOX AS FOR RPM DIAL THAT IS USUALLY WORKED THROUGH CRANKSHAFT SPEED SENSOR BEFORE YOU GOCHANGING SPEEDO DRIVE MAKE SURE ITS NOT A BLOWN FUSE

you can download the manual by searching online for auto manuals. The download I used was like 48 pages of information, all free of course.

Your Daewoo has an 2.2L engine and it's an interfernce engine. Which if the timing belt pop it will bent valve's. To align timing mark's both intake and exhaust cam gear's have a mark, on backplate of gear's at 12 o'clock there a mark align both gear's to that. on crankshaft timing belt pulley has a noch on housing back of gear at the 6 o'clock there a v cut, align pulley to that. Good luck

Diagrams are here.

remove thermostat and drill a small hole in it to allow the air to come up to header tank

There are no Daewoo dealer in the US any longer.
