When the car heats up and under hard acceleration I get a screech/whistle under the bonnet. When I stop I get a smell of exhaust through the vents. I am thinking it could be the EGR cooler. When it heats up a crack could open up more.
I have checked the radiator and I'm not losing coolant. Any...
I'm getting a new radiator today. Had over heating problems towing. They said the old radiator was very blocked with stuff like jelly and couldn't save it. They reckon it was like that because of mixing different coolants.
