What radiator options??

Check thermostat?

Radiator size is fine. People buy parts and dont kknow how to get the best out of each part which is the problem these days.

The issue with the halfsize is that you have a big gap next to the radiator and what happens when your driving along is that the air is bypassing the radiator and going through that big gap next to it. Think about it. Block that big gap next to the radiator and the air has no where to go but through the radiator. But then what can happen now is that the air will go over the top of the radiator. So thats where diversion plates come into the picture. Air is pushed back down and through the radiator. You are now using your radiator to its optimum potential.

Hope that helps.

considering getting this changed soon

I will look into getting some air diversion plates getting made just to block off the gap and top, this is really good advice.

Could water pump also spark this issue, if so how do I determine if it is not working?

And 90LAN can diluting it really cause this issue or you pulling my leg?? wtf

It said to dilute the concentrate and as far as I know your supposed to? WTF im tripped out now Did I do something stupid by replacing it or what

just do what i suggested, if that doesnt work then it was no harm in doing anyway. But to me coz you said you its worst when highway driving then i think that could be your issue, Also you have to realise it get really hot under your bonnet there especially when you force inducted as well. First thing to get rid of all that hot air trapped inside that engine bay. eg, slighty raising the bonnet ( closest to the windscreen end) to let the hot air escape. Even ducting the radiator by fabricating a shroud to direct the hot air elsewhere.All this will do keep your engine nice and cool.

Not only, all this can be done by you. So a very effective application both financially and the longevity on your car.
