As far as i can see from haynes and a French ZX workshop manual the pressure for both diesels is 1.4 bar. The French manual deals with the 1.4 but doesn't quote a pressure and my haynes is for diesels. Quinton Hazell's downloadable catalogue entitled 'Radiator caps and Thermostats' - doesn't contain any radiator cap information at all!

1 bar = 14.5038 lbsq in

so 1.4 bar = 20.305 lb sq in - quite a high pressure for a cooling system!

What the 'Haynes' book says is that the Max. pressure is 1.4bar.

Having a higher pressure than 0 increases the boilng point of the coolant.
