COOLING - WATER
The engine water cooling system on a late
model turbo car is probably running at the limit of operation with the
added heat of the turbo cooling water included. As mentioned above the
main function is to dissipate heat from the turbo housing to prolong the
life of the bearings and stop heat soak back.
This is the reason that some cars have "turbo timers". The timer is there
to allow the turbo temperature to stabilise and cool while the engine is
idling prior to turn off. This is especially important after high speed
operation or spirited driving prior to turning off the motor as the turbo
exhaust temperature could be in excess of 800 Degrees. If you don't have a
turbo timer you can do as I do, which is take it easy when you know you
are going to be turning off soon and after stopping just let the car idle
for thirty ( 30) seconds before turning off.
WATER TIPS Change your cooling system fluid with high quality coolant to
prevent corrosion and effectively remove heat from the motor and turbo.
Ensure your radiator is not internally or externally blocked, preventing
either water or air flow through the core. If your system is running
hotter than usual then many reasons can contribute to this, including
incorrect timing, lean air/fuel mixtures and other obvious reasons. These
might include low water level, leaking system, incorrect or faulty
thermostat, faulty radiator cap, worn or loose fan/water pump belt, or
even the unobvious rusted and broken water pump blades. Detonation is to be avoided at
any cost.
