For physical reasons, the engine 

temperature gauge shows the coolant 

temperature only if the coolant level is 

adequate.
During operation the system is pressurised. 

The temperature may therefore rise briefly 

to over 100 °C.

Never run the tank dry! 
Diesel engines: if the tank is allowed to run 

dry, bleed the fuel system as described on 

page 143.
Because of the fuel remaining in the tank, 

the amount of fuel required to fill the tank 

may be less than the specified tank 

capacity.
