Hey everyone

Just done one major surgery for my LMST

- Front absorber + mounting rubber 1 pair
- Lower arm + satay bush 1 pair
- Water pump, timing belt & aircon belt

Damage: RM740

A few more things that I need to change for my LMST

- Right drive shaft can see block colour oil leaking, lifespan reached

- Metal pipes for radiator showing rust especially the one for choke, in fact it is already gone case and the mechanic temporarily bypass / sealed the hole for choke pipe

- Aircon fan speed 1 and 2 no respond, only 3 and 4 blowing

Can any sifu enlighten

1. What if the leaking drive shaft is not replaced for a prolonged timeframe, say for 6 months? The leaking oil is from where?

2. What problem could arise if the choke is bypassed? Can't start in the morning?

3. What could be the issue for aircon fan speed 1 and 2 no respond but 3 and 4 blowing? What has to be replaced?

TQVM

Hi Albert

The drive shaft leak stain can be seen on the lower arm so I assume it is at the wheel side?

Okay will check it out tmr

When the mechanic was replacing the lower arm I asked him about the leak then he told me it was the drive shaft lifespan reached

So I asked him if not replaced dangerous or not

He said no the most the oil will leak finish only

Can replace later which he told me about RM200+

He was too busy yesterday perhaps

My LMST radiator fan is not spinning despite radiator is hot and I plan to replace the sensor to see if it is the culprit

Do I just unscrew the old sensor and screw in the new one?

And how do I connect the plastic connector back? Both the connector and the sensor is like a L shape

My bad as I disconnected it and did not take notice before doing it

Hi Albert

Good to see you back and thanks for your reply

Ya I was worried if I reconnect it back wrongly, not too sure how to put it... 180 degree / upside down the sensor won't work but I guess as long as connected it will work? Since my dashboard is still displaying the temp bars I guess it is

Today mechanic got an hour to spare for me so I drove my car to his workshop to get it solved

Tested fan motor not working so got it changed to a new APM motor together with thermo switch, and he threw away the thermostat

The fan is spinning fast now

Total damage RM250

Next to do but need to wait for him to be free

1. Steering column, not sure the whole column or partial because the rubber dropped and the steering will wobble up and down. For now I just pushed the rubber back whenever it wobbles

2. Not sure what is the iron casting part called (the part that the temp sensor for display is screwed into) he said need to be replaced and need time to source since spare part is scarce now

IINM it is due to rust

When opened up the part to throw thermostat the inside has a layer of mud or rust like color deposit

Radiator also flushed out some when changing the thermo switch

1) I recalled when I sent the car for another radiator workshop for leaking he told me some parts that are connecting the radiator rubber hose are corroded and very hard to fix the rubber hose and might not be able to hold the rubber hose if corrosion worsen. Not sure is that part of this intake manifold.

2) I don't think he added coolant as he only filled in pipe water. Guess I better add in myself as I saw Proton ori blue color coolant for 1L is only like RM25 to RM30. Is 1L enough for the car or required more? And should I avoid pipe water and buy those 5L distilled water to mix instead?

3) Not sure where he is gonna source it from but he did tell me have to order and the item excl. labor will be about RM350. He said if can't source then need to weld with aluminium which will be expensive as well.

1) I think IINM my car the corrosion also at the insert photo. The radiator workshop told me if further worsen the hose will have no place to grip anymore. My autochoke hose also disconnected due to corrosion and my mechanic sealed the hole with a screw and some special glue temporarily.

2) Can you advise how many litre of coolant should I add?

By the way, is thermostat necessary? (P/S: I don't start my car that often in early morning)

Thank you

The mechanic did tell me the autochoke hoses will be restored after the manifold replacement

Thanks for your advice on coolant & thermostat

Is fully synthetic engine oil suitable for 2005 Iswara / Saga LMST?

Actually my car just suffered from oil seal leak and it was not even on fully syn (only using semi syn so far) and timing belt was only replaced in around 2022

Read on the net that if using fully syn the seals of old cars might not be able to sustain
