far more important than that - we should stop to think why car engine's are designed that way. i read somewhere, can't remember where... every single part of a car is important. it is engineered that way, if a part is not important, why would the car manufacturers include them? remember each part is COST to them. i know many mechanics out there recommend to remove the tstat, why i don't know..... maybe they are more clever than the car manufacturers... (and when i say car manufacturers, i really mean the original dna of the iswara, which is mitsubishi car engineers....)

yeah, so in the case of thermostat in our 4G1x, what's the reasoning for removing it?

Iswara thermostat is rated at 88 dec C I think, and most spare part shops will sell 82 dec C (may be wrong, just basing on memory here).

This means early morning, when your engine coolant is say ambient air temperature 30 deg C (or 18 at genting), and you start the engine, coolant continuously flow through the engine block. This causes the engine to take longer time to reach optimum operating temperature, and when you cruise on highway without accelerating, you might have lower temp than normal cause coolant is circulating all the time.

If you have the thermostat, then the coolant will NOT circulate and it will very quickly warm up to about 8x deg C and that's when the tstat opens, allowing the coolant to circulate through the radiator removing excess heat. From here on, the tstat acts as a regulator, opening and closing when necessary to keep the coolant at 8x deg C consistently.

Also note that if you remove the thermostat, there is less 'resistance' to the coolant flow, which means coolant might be circulating TOO FAST through your engine block to pick up the heat - same concept as home water shower heater, try maintaining same temp, then start turning off the tap simulating water flow resistance from the tstat and you'll start to feel the water becoming hotter and hotter even though temp setting is the same.

So the side effects of removing thermostat is that engine may take longer to reach optimum temp or possibly even run at below optimum temp in certain conditions such as light throttle cruising at night or highways. I do know that if the engine is running below optimum temp, you'll get bad fuel economy. Not sure about other side effects but I'm sure a bit of googling will help.

So again, I don't understand why mechanics simply recommend to remove thermostat! The tstat is just to regulate the temp, not actual overheating issues - there's something else wrong with the cooling system if it consistently overheats and that should be fixed instead of removing this and removing that.

Same thing happened to my car few months ago, bought the original center meter (speed/odometer) for RM150 I think and also the speedometer cable can't remember how much but less than RM50. Then diy took out old and replace it. Not difficult, just have to be careful when removing the center part of the meter from the meter housing.

No idea about the fuel meter, but before you change that - make sure it's the meter that is the problem and not the sending unit...

I don't know whether it's expensive or not but it's original Proton part. I bought from nearest spare part shop, told them I wanted original proton. So far ok. I also saw this blog/shop selling around same price:

http://jenfookbee.blogspot.com/2011/07/pro...eter-gauge.html

I've been using it for 6 months already now, working perfect no problems. I checked my records (I keep full records of all parts/services) and it was RM150 for the meter, RM30 for the cable. All ori Proton part bought from nearby spare part shop.

RM200 for whole meter panel, probably second hand but remember these are wear and tear items, if you buy second hand it's like lottery, you don't know when it will decide to kaput again then the RM200 masuk tong sampah.. see these...

So high mileage still asking for so high price Personally for me, I'd rather buy new part for these wear and tear crucial parts. Other non crucial body parts no prob buying second hand.

Just my opinion but everyone's different

Maybe shop around and see.... I just did quick survey and felt RM150 was fair price but I could be wrong.

CAI guru a lot here... wait for them to reply me play stock standard only, don't do any mod....

you mean you changed all 3 meter panels+cable - brand new, for RM200???? where?

ps: sorry I misunderstood... so you changed just 1 meter panel for RM200... around the same price, mine RM180 plus the cable.

Original Pivot? I'd be careful... take a look:

Your friend offering it for RM68 only? Hard to believe so beware...

I believe the alarm sound is just the alarm siren or connection problem.

For the knob popping up again immediately when you lock it, is it happening only on 1 door or all 4 doors? If 1 door only, you may need to remove and check the actuator. After some time, you need to lubricate all the moving parts of the actuator (use WD40) or if it's faulty, replace it original costs about RM50 or so I think.

If all 4 doors popping up, then I have no idea sorry maybe alarm kaput?

Yes to access actuator remove the door panel then plastic. Those black stuff will still be sticky after that you can just restick the plastic back. If you don't plan to remove the actuator, make sure you have a long nozzle spray as it's quite hard to see/access it. If you plan to remove then i think it's 2 to 3 screws holding it in place cannot remember exactly how many but not hard to figure out.

most prob actuator linkages need some WD40, or the actuator kaput already. mine had same prob on passenger side bodoh bodoh go buy the actuator RM50 to replace later found out just need some WD40. anyway replaced it since quite old already now cantik!

no, the linkages.... all the long rods linking the knob to the actuator. actuator itself nothing visible to spray, it's all the links i.e. to the door handle, to the door 'striker' whatever you call it. just remove the plastic and look at all moving parts when you push pull the knob and spray every link!

wah 2nd hand saga 15k for 10 year old? so good price?

my iswara '99 i think can sell around 4-6k only, the last iswara year 2007 models also just a bit above 10k market price I think. but maybe if tip top condition well looked after probably worth paying a bit more.

You can check indicative market value here at www.autoclaims.com.my - will need to register for free account, and i think some valuation not accurate but good as reference point.

hi all, anyone facing the autochoke problem in their iswara? morning start rpm low around 500, after warming up perfectly fine around 800-1000?

i asked a workshop nearby, he said can repair using a choke repair kit. total cost about RM150. i called local spare part shop, they said don't sell the kit.

anyone know where to buy the kit, and whether RM150 is a fair price to repair this? thanks!!

I used once, no effect whatsoever... just burned RM18++

Not to me.... I had better effects manually cleaning the carb with carb spray and changing the distributor cap+rotor.

wow, this looks like a nice iswara.... anyone know how much to repaint iswara like this? between 1-2k?

http://www.mudah.my/Proton+Iswara+1+3-13133165.htm?last=1

anyone recently repainted their iswara? care to share and feedback/reviews?

i asked before last time, in segambut area quoted me 2k!!!! just for metallic paint, crazy overpriced i feel.
