Thanks for the replies.
jedamotorsport: Isn't the bonnet sealed along the back normally? As far as I can see there's only some small holes along the back behind the engine to allow the air in the compartment to escape, apart from underneath, of course. I can see how this would help cooling but at the expense of the blowers sucking in all the hot air

important when it's 30+ and your stuck in traffic, which leads me on to the next point about how little air is pulled over the A/C rad, even when the fans blowing because of the small slot in the bumper and small top grill (OK when doing 35+ mph though, nice and cold- for an old car). When you look round the car park it seems that the Escort has one of the smallest areas for the ingress of cooling air, I did read on a website that the Zetec needs to run hot because damage will occur otherwise, something about the oil being 100c so maybe this is why the area for cooling is so small.
Is there any temp mod that can be done for summer to improve the air flow when the fan is running so the A/C is cooler when in traffic? It's forecast for 33c tomorrow and they always get it low

(I wish my A/C was as good as when my dad's new Focus nearly froze my feet on a hot day in Spain)

I wouldn't worry about it mine runs hot too i mean when i'm constantly driving without stopping the needle will stay in the middle but like you say as soon as your slowly driving around town or stuck in traffic the needle creeps up pretty quickly (about 5mins) hits the L on NORMAL and the fan kicks in. I've renewed my cooling system so i know its running properly and like you i live in Spain and its always hot, but as long as your coolant is always kept topped up and your cooling fan kicks in when it should i wouldn't worry :-)
