Thanks TT. Apparently agent is in Abatale and have the Daihatsu original part. However after cruising through Panchikawatta I could find the same part around same price. Yeah IR are costly. But engine is smooth again.

I need to know a place around Colombo to purchase genuine NGK spark plugs for Mira ES car. Below are the part numbers. NGK IR SILKR6D10G - this is the original came in car Found on internet below are also compatible, but not sure. Denso IRIDIUM POWER IXUH20I Denso IRIDIUM TOUGH VXUH20I NGK IridiumMax LKR6AIX-P BOSCH Double Iridium YR7MII33X Appreciate your advise. Thanks

I had cooling issues (radiator leaking / broken fan) with my previous car (Suzuki Swift) which makes the same noise when it runs out of coolant. Ones radiator and fan got fixed the noise went away. Not an expert but just sharing my experience.

Well mine was doing around 15 kmpl (colombo) but suddenly it dropped to around 13 kmpl range. I feel it has some pickup issue also. Specially with AC ON. I did service last week but no improvement. Expert advice welcome. Oil - Toyota 0W-20 Oil Filter - VIC C-110 Air Filter - VIC A-752 Petrol - 92 ODO - 16,xxx (bought around 14,xxx)

Nope. And the RPM issue fixed after a proper clean up in throttle body.

Mine does 9 km/l in city traffic with gentle driving.

Maybe the Sankei available in some shops not original or good quality? Yes will do like that.

I have a HT51S and my radiator cap is Sankei 0.9. When I asked from my mechanic he advice to get a good quality reconditioned one rather than low quality new one.

Update 3: Much better experience after Pump/Thermostat change. Although on a test ride in heavy traffic again heat went up and came down few times. Although the radiator was cleaned before the mechanic suggested to check again. Cleaned inside and outside along with AC condenser. So far seems the issue is ok now. After a journey I feel the car get less hot (engine compartment) now. With that again back to lower RPM issue, No problem as long as the vehicle is on the move. But when at complete stop the RPM goes below 700 and car starts a little vibrate. Not sure whether a ICV or TPS issue.

Radiator cap was in good shape. If you mean "compression leak test" is on radiator, yes done and was ok.

Yes its going into the coolant reserve and overflowing. There are coolant on engine and surrounding which were overflew. Fans I checked with the mechanic and they working as intended at correct speeds. Done bottle test and no bubble so they told gaskets are ok. And no leaks either. Sure next time will keep AC on. Thanks Stig. Update 2: So I went to new garage and unfolded the history. After initial checks they went straight for thermostat. It was faulty and opens only a little. Also showed signs of a previous seize. Checked water pump and it was squeegeeing when raotate from hand. Both needed to be replaced. Its getting fixed now. Will update with the progress soon.

Having a similar kind of issue. Same car HT51S. First it started with random heat going maximum. I cleaned the radiator and filled new coolant. Problem was ok for about a month and my radiator fan died suddenly. (Maybe it overworked previously.) Replace and it was fine for a month. Then again around 1 month after I saw RPM meter varies as idle. I did a engine tuneup and OBD scan reveled issue with Cam sensor. (P0335) I replaced both Cam and Crank sensors. Again it was fine few days and again it heated up. After letting it cool down I reached home without any issues. (Without AC that is as a precaution) Once home I checked and saw little coolant was missing. Guess through reservoir.. Could this be ECT sensor, Thermostat, Radiator cap or something else. Whats the correct way or place to find out.
