Re: overheating issuse

Mine does similar but I have to sit around 120kph. I can tell you what it is It's the thermostat is open and the water is circulating too fast to cool.

When mine does it I just switch on the thermo's and it cools nicely.

Re: overheating issuse

What sort of radiator, what sort of fan, what sort of shroud, what size pulleys are they (roughly; are they ford or aftermarket), what sort of water pump.....?, there are a few variables.

But, your symptoms sound like a shroud issue (at a guess anyway, without all the relevant info). A shroud not only makes the fan suck air through the radiator at low speed/idle, but it also slows the air down at high speeds on the road. If the air is going too fast (around 100.....) then it doesn't have time to absorb heat from the radiator as it rushes through the core. If you have a shroud fitted (of the correct type), then the air has more time to pick up heat and the engine runs cooler.

That's guess number one. Most people don't seem to realise that the most efficient cooling system (rad, fan, shroud, pulleys, etc) is the one that Ford designed. Obviously a strong engine will need the best that Ford offered (3 core, extra width radiator for XA onwards, flex fan, correct pulley sizes, and, most importantly, a functional thermostat !!!...).

Re: overheating issuse

Could also be an overbored block..............

Your water pump may be cavitating and not circulating the water........

Tou may be running the Windsor stat instead of the proper Clevo one, the look similar but as some of us here have found out work and seal differently.

Search these forums and you'll find literally hundreds of replies on this issue and some damned good advice from those of us who have been there......

Good Luck

Re: overheating issuse

I run the DT66 myself. I notice it's a little more steady with temps.
