Hi,
I am using Octavia TDI 1.9 2005 model (64000 KM). Radiator fan is not working and temperature meter showing around 100. Please tell me the best place to replace it Delhi/Noida, how much it cost. Or can I manage by repairing.

Thanks,
Raj

Raj, if the engine temperature is reading range 90..100C, that's entirely normal for this engine (any tune). Accordingly, I think you have a fault with the air conditioning system.

Since the radiator fans aren't running, then the A/C doesn't seem to be coming on properly for some reason. Therefore I'd check the following:-
1) Is the drive pulley secure on the compressor shaft? The securing nut has a habit of loosening, which can cause the drive shaft to round off, so that the compressor won't turn over.
2) Do you have evidence of the air conditioning having been regassed at some point in the past? The car is 6 years old, so it really needs doing even if there's no other fault.

Obviously, I'm not in a position to recommend a repairer to you, but here in the UK you can find specialists who do nothing but automotive A/C system work, and are usually cheaper than a Skoda dealer would be.

Thanks Neill for suggestion, sorry for wrong information, today i checked that AC fan is working....Actually i was driving it from long time but didn't see temperature reaching beyond 90C. yesterday i saw indication for low level of coolant then i filled it and now i am seeing that temperature reaching till 120C ...my radiator fan was not working from last 6 month but temp didn't reach above 90C. Is there coolant quality issue or something else.

VAG G12+ coolant (the orange/red liquid) is not just an "antifreeze". It's also an anti-corrosive package and a "water wetter" (this increases the boiling point of the coolant), so if you've got less than 1 part G12+ to 3 of water, add G12+ to reach that level (presumes car's normally in Delhi; I would advise a 1/1 mix of G12+ and water if you drive in the mountains).

Also, you may have a problem with the pressure seal on the coolant reservoir, so when the engine is cold (first thing in the morning, or when you come off shift if you're a shift worker) remove the filler cap, and clean both the top of the bottle and the seal on the cap. After this, it starts looking like you may have a coolant leak, and diagnosis gets difficult when you can't see the car.

Thanks for your valuable input, I checked that found coolant level is very low that point to coolant leak, then i go to workshop. Mechanic checked and found there is leak from one of horizontal pipe (white). They replaced it.

Neill, I have one query regarding timing chain. Is there any limits after which we have to change it. Actually a mechanic told me to replace it because it completed 64000km.

Thanks,
Raj

This car doesn't have a timing chain, but a rubber timing belt ("toothed belt" in the English language service schedule and log). The UK replacement recommendation is every 76_800km or 4 years, whichever comes first. When you're getting it replaced, have a new water pump installed at the same time, because it takes about 15 minutes when the timing belt is off, and 3 hours if you have to strip the timing cover and belt in order to replace the water pump.
