Elantra 2.0 Belt Replacements

My Elantra has clocked 155,250 km. Have 2 belts that need to be change, Air Cond compressor  belt and Alternator belts. No power steering belt as this elantra is using electric power assist steering motor.

Both belt from different maker but most important are the belt number

4PK890 - Alternator

4PK845- Aircond

My Elantra 1st aircond service.

The elantra has clocked 67,300km and its coming to 4 years old by Feb 2012. Best to have the aircond system service by my regular workshop. I do learn something new ...it wasn't easy. Work together with the technician was fun... it help me to understand how aircond system component has change over the years. 

I requested the dryer to be replace and aircond compressor oil to be renewed with fresh oil. The aircond compressor was removed from the mounting and all the oil was drained out. About 200ml compressor oil was fill up.  

In the process, it was discover that the aircond belt has many cracks along the v-grooved, immediately I request it to be replace. 

The original aircond belt marking

The belt was replace with new belt..it seem you can use 4PK 845 or 855 belt. 

In order to removed the aircond belt, need to slacken the alternator belt as the main pulley share 2 v- grooved, for alternator and aircond compressor. Check on the alternator belt, all seems to be in good condition, should be able to last till 90,000km

Next...the dryer...normally we see the dryer as a canister that is separated from the condenser. Whenever we service our aircond system, should the dryer is choked, only the dryer canister is replace. But with new design on the elantra, whereby the dryer shell is welded to the condenser. Example as see below

With this design , it allowed only the dryer element to be replace. By removing the bottom cap, will exposed the element. But more work need to be carryout..the aircond fan need to be removed.

The whole condensor unit to be lift out.

And whole condenser with dryer is removed from the engine bay

The condenser is place on the working bench and you need an allen key to open the bottom caps of the dryer. However the caps are made of plastic...need time to removed.

Finally manage to removed the plastic cap

This is the dryer element...being packed nicely. Inside it contains dry silica gel to absorb any moisture of the aircond gas.

The condition of the plastic caps was terrible as need to apply force to moved the caps. I was worry it might not fitted during installation. However lucky managed to do it slowly and carefully.

 The old silica gel was replace Denso silica gel..

Fyi..some dryer caps are made of  aluminium however my elantra are made of plastic....those caps are unfortunately are not universal size. If the plastic caps snaps or damage, the whole condenser will have to be replace!!

And finally, pressure test the condensor found no leaks and the condenser is washed with solvent to removed all the dust and dirt sticking to its cooling fins.

 Overall check, found all system working good...
