  1. Is it true that engine sound may reduce or increase based on the engine oil brand used? For an example assume oil used is 15W-40 and brands are Mobile and Castrol.. This is just for my curiosity..

      About somethings that the other have said...yes..I suppose sometimes additives can help muffle out some knocks and vibrations. As for the viscosity of oil...in SL we have a higher ambient temperature so our engines run hotter than normal, especially considering the traffic we have to sit through.  The issue with a light oil like the 20 is that although it helps with engine efficiency in terms of lowering component friction in the car it is not that good in thermal absorption...thus in extreme heat as the engine runs for long periods of time or in high heat..the oil thins out and then you start hearing valve knocks and clinks....when you put a thicker oil the thermal absorption is a bit better and the oi does not "thin" out as much....in fact if you are a heavy footed driver and you push the engine to the max..even the 30 will start making noise and you would want to put 40...I know a few 4age owners in SL who use 40 because they like to red line their engines a lot :D

      assuming the velocity is same, only difference it could have is based on the addictive's used by each brand. Is Castrol mineral better than mobile? how about helix do they also have mineral?

    4. iRage


      I have no idea....are the addictive types printed in the packaging ? (highly unlikely when you think about it and jsut refer to it as secret technology) I suppose different manufacturers use different percentages of zinc, detergents, etc which can help (or harm) the engine in different ways....

  2. What component decides how long the AC should run? Assuming its a manual car AC system

      @MrCat how to determine whether its over filled or not? however, now the AC cool is great (just like brandnew).

    3. MrCat


      An A/C technician should be able to find if the high pressure switch is triggering. There is also a known pressure/gas volume which should be set based on car model and refrigerant type. Search here for example:   https://www.hella.com/techworld/au/Technical/Car-air-conditioning/Car-refrigerant-oil-filling-quantities-2114/#

      @MrCat thanks for sharing this. I need to get this checked as there seems so be no leak so far and car gets cool as expected after refilling. 

  3. Looks like the Merc is getting there slowly. Work is dragging a bit than I anticipated. Engine and all interior parts are out for a fresh paint job. Attending to rust spots before the full paint job. I might need to find a plastic cluster cover because the existing one has a small crack.

      exactly. My father-in-law always says that mercs which were built after 90's are crap. because that's where all the electronics came into action, things got complicated and expensive to repair and a nightmare for the owners. and unlike the w123, this is suitable for every generation as by doing a simple alloywheel swap it could give a look of a teenager car to a old person car. its that easy.

    3. □AVANTE□


      Electronics are vital for modern cars but merc just does it wrong..Carthrottle did a video on an early 2000's S-class they got for £1000 & while it's a dream, the mechanic himself deemed it's "uneconomical to repair"..who wants a merc than you can't keep for a long time? W115 & W123s broke records for crying out loud.

      Same has happened to Alfa romeo, Peugeot, BMW which were 90's legends and sadly now the time for modern Hondas is up & is time to join that list.

    4. PerfMad


      true that.. now adays all car manufacturers focus is not on vehicle selling market but the parts market. So i believe mercs stood in that line before the others may be.🤞

    Steering Rack Limiter

    Knowing Swifts are prone to have rack issues by its design, i would suggest you not to go ahead. However, at the end of the day its ur vehicle and ur money which is on the line. If you have enough money to replace it, then why bother
  5. If its just the radiator cap which was faulty i think the price is bit higher. I replaced mine but costed me only 750 LKR. Anyways, glad you were able to resolve your issue. Happy motoring
  6. glad you were able to fix it. Was it just the radiator cap or top which was leaking?
  7. I have no idea about repair location around Matara. But do you see visible leak in radiator or related hose? If the radiator is leaking then any 'radiator house' shop can do the fixing. Better do a proper pressure test and then fix the leak. First try to identify the leak
  8. I'm searching for Honda City 2001 windscreen cowl clips. Does anybody knows where I can source it locally?

    Given below is for your reference.

      Try checking Link Enterprises in Jubilee post if you are around Nugegoda area. They have many of the clips you need at a very cheap price. Be sure to take a specimen with you

    3. PerfMad


      some are cracked due to heat.. so wanted to replace them to look like new.. do you think darley road shops may have em?

    4. PerfMad


      @Dee Jay thanks. Nugegoda is closer to me.

  9. My advice drive the car and check your coolant level daily and keep track on it. If its loosing coolant you will identify it since you will see coolant marks. However, as per your explanation you have (previous owner) replaced the top radiator tank which fixed the issue. At times its also advised to change the radiator cap along with it (with the correct pressure cap). There is another tank located in the bottom of the radiator, if you are coolant level is reducing, start the car and check for leaks in radiator cap, coolant hoses and bottom tank. If there is any leak it should be quite easy to identify due to coolant colour. Keep us posted on the findings. Make sure to check coolant daily to avoid any bigger repairs and happy motoring!!
  10. true that. Make sure you take all ur meals packed if possible take a portable chair as well
  11. This is the place https://www.google.lk/maps/@6.9671699,79.9079507,3a,75y,328.9h,79.16t/data=!3m6!1e1!3m4!1snUOb0Ax5Kcu42UxHRP8k3Q!2e0!7i13312!8i6656?hl=en his contact no - 072 214 2143 (if you are going better go in the morning and stay there and get it sorted, otherwise it will take ages to get ur car as he is a busy person)
  12. im suspecting the crank position sensor as well. If you pay a visit to Ravi (kelaniya) he should have plenty of parts to swap and verify.
  13. Guess what... My father-in-law is secretly restoring a W124 :girl_in_love: :D yesterday he took me to show that it got a good 5 cylinder engine and has not been used much so as per him engine is in good condition.. Only some of the body parts needs bit of attention and its been taken care by the tinker after everything is done, going to do a full paint job after rust proofing..

      @□AVANTE□ yeah same here. i think there is a different version which comes with turbo. But the one which we are restoring and the one my father-in-law owns both are 5 cylinders but non-turbo variants 

    3. alds


      The best looking merc IMO. There's one for sale on my way to work begging for a good restoration but this is one of those "aasai bayai" cases for me. :D


    4. PerfMad


      @alds do you have any pics ? if the motor and interior is in good shape then the rest is pretty straight forward. I've found couple of shops who has full car for parts too if needed :D


  14. Gonna check on a Merc this weekend (if time permits). Let's see whether it will turn me ON 😂😋:car-smiley-001:

      @tiv same old W124 :D 

    3. tiv


      All the best! 

    4. PerfMad


      if not, this time i'm gonna restore one :D $matters though 

  15. What should be the charging voltage range without load and with load??

    1. tiv


      Range total 13.8 to 14.2 max 

      14.2 under no load with a large alternator for a dual battery setup or dual ac setup, above mostly in diesels 

      14 to 14.1 in a relatively small car alternator, non hybrids 

      13.8 with factory load, mostly in all setups 

      13.4 with large non factory sound system with normal load

      13.2 and below alternator most likely faulty or loose belt 


      But mind u newer cars have alternator clutches that disengage and engage alternator with load and battery status so this is not fully reliable, also ISG units in Suzukis do the opposite and go to 11.9 in load as it propels the engine and goes to 13.8 to 14.2 whilst idling. Hybrids and electric cars run at a much lower voltage and narrow range and rarely touches 13v 12.5 to 12.8 mostly  

    2. Hyaenidae


      I'll check tomorrow

      If I remember correctly it was about 14.4ish w/o load

    3. PerfMad


      well mine was reading around 13.7 ish (if im not mistaken) with load (lights and AC) my garage said charging system is fine. But one battery shop said battery is good but charging system is performing low under load. So looking at ur answers, my charging system seems to be working fine.

      Battery is a exide and 2.8 years OLD now
