Hi.. I'm needing some help as not sure what the problem is. Was out driving yesterday and temperature shot up really quickly. Must have been driving about 5 mins or so and it has shot up to nearly 90 degrees.

So me being me, I thought nothing of it. This morning, was driving again and same thing happened. When in heavy traffic, fans kicked in so that not a problem.

I thought i'd check coolant. Opened the cap and the colour was kind of limy green.. checked engine oil cap and no white residue or anything like that.. any help would be appreciated. Oh yeah.. previous coolant used was red so not sure why it's turned green.

Car is a 6, phase 3, 2000 model.

Depends what you mean by quite quickly, but:

a) it could be completely normal. It is not uncommon for temperatures to get very close to the red after all but a minute or two sitting in traffic. Catches everyone out, no matter how used to it they are!

or b) you could have an airlock somewhere in the cooling system.

You can easy bleed the system following the instructions in the FAQ section.

[In summary, use an upturned pop bottle on top of the header tank to increase the water pressure, then open the bleed valves (on the i) nearside top of the radiator, ii) top of the thermostat housing above gearbox and iii) on the heater matrix pipes next to the exhaust heatshield) in turn until coolant is flowing.

Yeah I suppose you're right khj100. It was just that the temp was going up faster than it normally does.

It did reach 90 degrees within about 10 mins of driving (not stuck in traffic though). I suppose it could be the weather (wish it was hotter tho.. going Spain in about week's time so can't wait! )
