Engine Bay Heat

[Alpineandy]

Hi, as a newboy to Vees who hasn't had the nerve to go snooping round the engine bay much (OK, I'm a pretty cr4p mechanic so it's wiser for me to stay out of there!). I notice that the engine bay gets very very hot, especially after the engine is turned off. Does it (the 230) have an engine bay extractor fan and if it does, should it run on after the engine is switched off?
Cheers

Section 17B-28

ANTI-PERCOLATION FUNCTION
The anti-percolation system is controlled by the
injection computer.
The coolant temperature signal used is the one from
the injection system.
After the engine is switched off the system enters
standby mode. If the coolant temperature exceeds the
limit of 102˚C during the 10 minutes after the engine is
switched off, the front fan unit is controlled at slow
speed.
If the coolant temperature falls below 95°C, the front
fan unit relay is cut off. The fan unit cannot be switched
on for more than 10 minutes.

Likewise, if the temperature in the engine
compartment is greater than 70˚C ±10 after stopping
the engine, the rear fans are actuated.

OPERATION OF THE FRONT FAN UNITS
– The fan unit is controlled at slow speed if the coolant
temperature exceeds 99˚C and is switched off when
the temperature falls below 96˚C.
– the fan unit is controlled at high speed if the coolant
temperature exceeds 102˚C and is switched off when
the temperature falls below 99˚C.
OPERATION OF THE TEMPERATURE WARNING
LIGHT
The coolant temperature warning light comes on if the
coolant temperature exceeds 118˚C and goes out
when the temperature falls below 115˚C.

I suspect mine's broken then [smilie=icon_aaargh.gif]

Fans are located inside the pods. When they do come on you'll certainly hear them (as will everyone near you)

Don't panic it's quite normal to feel the heat, it will naturaly vent through the side pods when parked up. i'm not sure of an exact test, but try getting the engine upto temp and then leave it to idle until your front rad fan kicks in. Then turn off the ignition and see what is running or kicks in?

Ditto, My cabin has a fair bit of heat build up too, I had no idea about the fans...... I was having a good nose about mine yesterday for the first time and did feel it venting through the pods.

The spec say engine compartment temp of 70 or above, So i'm guessing there is a thermostat in there somewhere.

Do we have a wiring schematic on here anywhere ?

 

[Jamesv6]

There is an ambient temp sensor screwed into the rear bulkhead panel, near the expansion bottle. A little round black thing with 2 wires on it.

Spot on James, I'll have a look for it.

There's a few post about this.
Switched mine to manual.
