the 2.7L is a V6, to perform a drive cycle you need 1/4 to 3/4 tank of fuel and do not exceed 59 mph for a good 10 to 20 miles and then a key cycle to check if it did not go try again . best when cold start up

You can get that in pieces from the service and repair manual. You can download that for a small fee here.

Throttle position sensor, check that, or fuel pump/filter

Replace the fuel filter and have the injectors cleaned.

Antifreeze is full? If you are moving down the road and it overheats it isnt the fan. The fan only cools the engine when the vehicle is sitting still.

51 to 54 foot pounds for a cold engine. 58 to 61 for a warm engine.

1998 Hyundai Lantra "G4GM" engine 1795cc.there are two heads or blocks, one is called the M10, other is the M12, figure out which one you have cause the torque is different for stage one by 5nm........... Dont get confused theres 2 different engines so 2 different torques for stage1---------
heres the full details: Stage 1 - m10 = 30nm / m12 = 35nm-------------------------- -------- Stage 2 - tighten by 60-65 degrees ------------ stage 3 - tighten by 60-65 degrees. no sequence is given in the data book for tightening so go off what you thinks right, it doesn't matter on this engine.

You have to use a ring compressor. Available at any auto parts store.

If the replacement thermostat is good, and installed properly, then the temp sensor might be bad. I hate to tell you ($$$$$) but waterpump could be bad (more expensive)

try pushing the clutch to the floor with you toes if it starts and won't unless you push to the floor its the clutch start switch 22 bucks at auto zone i will be gettng help installing the new one i will let you know.
