Boxster 986 - Cooling Fans, Operating Temp. (Stage 1 & 2)

[ooid]

Is there a quite specific degree or level for Stage 2 fans? The car's manual also quite vague about this.

I've recently discovered my stage 2 fans (the loud ones) does not start even hitting the heating level between "80&120". It used to start quite loud, right after 80 (near right side of 0) but since the engine rebuilt, it operates generally between 80-90 but never heard the high fans starting?

Today after about 1 hour driving in the city, (11 miles maybe in total) the level hit the "line" between 80-120 but no fans? it was slowly going down though not sure why, maybe AC?

- Tried to check if the resistors working by turning AC on, but can not hear any fans noise, as the engine quite loud already.

PS: Coolant level is up, no funny smokes, smells or weird action on the engine revs.

Thanks all.

Yes the loud fans just started today after hitting the line between 80-120. (The traffic was a nightmare today, did about 11 mile in 50 mins, thanks to london road-works)

Looks like both balast resistors dead. OPC quotes me 400 GBP for replacing them.

Original resistors cost 150 GBP and my local garage offered to replace them free of charge if I order the parts by myself

The resistors are not cheap are they! I actually ordered a complete fan assembly second hand for mine assuming I could take off the resistor to fit to my car. Unfortunately the resistor pack fitted to the used fan assembly that was delivered was also faulty, so I ended up getting a second hand fan for nothing and then having to order up a resistor, new, on it's own.

I have a better solution. They should just ban TFL bus, vans and slow-ass construction trucks from central London! ..Seriously, my temperature does not go above "80" until I hit another traffic jam. Not the mention, most of the routemasters half empty actually,they just cause more congestion.

It was like a "fan" symphony of the cars in traffic today, when I open my driver side window and listened to all other cars, running fans to keep things cool

By the way, did you buy those "24 GBP" used once from ebay? it says they are working, but looks like they are dodgy!

I've done a total of 120 miles today on m11. No congestion, traffic or non-sense stopping, usually between 50-70 mph. The gauge never went beyond "8" of 80. The same gauge usually operates between 80 & 100, in central London due to low-speed zones and massive congestion in less than 30 mins driving, and if the weather is quite hot, the high fans kick-in.

I might be wrong but really it might explain how most of these cars have engine issues if they are being driven in the city for a long time.
