Indika Rathnasekara's Blog: Event full weekend

Saturday, yesterday , started the day by going to the service station at 6:30AM in the morning.As usual I was the first to the service station and I was walking up and down in the premises till they started.Then came the owner of the station and he opened the doors to the pump house and generator house.

After about 45 minutes , the service man started the work with my car.It took 3 hrs to finish the job.

Then I took the car to the Tissa Electricals to check my radiator fan.The problem I had was , it was boiled when I come to the office on last Monday and I thought this may be due to the fact that my AC condenser fan was not working, the clue was I saw my heat indicator going up and when i turned off the AC it came back to the normal.So that was the history.

I told that story to the technician who run the place and I told I need to lay a harness to my power doors.After the removal of manual doors last year I replaced them with power doors, which has the options of power shutters , power mirrors , central locking , but never had a chance to complete the laying of the harness.

Then owner asked one of his technicians to take a look at this and Sampth is the name of this guy.Very talkative guy.After spending few minutes with him , I realized that he is not only talkative but also competent which is the most important thing.

Then he started to explore the vehicle.

First what he did was took the Carman Scan II diagnostic tool (a hand held device) which can be connected to the ECU via the interface provided (OBD-II),see the image at left.

Using that device he turn on/off the radiator fan,that concludes the signal is correctly passed into the fan, from the control unit.Then he concludes that by judging the speed of the fan, it has to be replaced and further checking the AC condenser fan it also has to be replaced.

Found a original AC condenser fan and get the fan unit and put it into the existing bracket.And found a radiator fan and replace it.Since Tissa electricals had recondition items , it wasn’t a difficult job for me to get the required fans.That saved me a lot of time.

The story was not ended there.While inspecting the fan, learn that the two power transmission belts also need to be replaced.One belt was already started to break from the edge.He said better to replace both at the same time.If I drive another hundreds of Km’s with those two, I could well be sit on the edge of the road with hazards on.

He recommended two brands to me which I haven’t heard.Because I am new to this belts.One was “Brando” and the other one was “Mitsuboshi”.

Then they started to remove the belts from the engine and by no means that was an easy job.

While it was going on Sampath started to remove all the door covers(apostings) and and estimated the length of wires required for the wire harness.

Estimation was 30m from number 14 and 10m from number 9.The number indicates the number of threads in the wire.That is 14 threads and 9 threads respectively.Plus power mirror switch and 3 gum tapes.

I had to go to “Pathma Motors” at kadawatha to bring those belts plus others.It took 1.5hrs by bus.
