Engine overheating problem
Jun 24 2010
Hi all, i'm looking for some help in fixing my overheating problem. I've got a 1.8 Mk2.5 Mx5, been a great car until i had an MOT done last month and ever since it has been overheating (it did pass!). Previously the temperature gauge always sat around halfway up, now after a journey of 15 miles plus it goes right up to the max. I can get it to come down by having the heating on full blast but as you can imagine its getting a bit too hot too handle in this weather!
I've cleaned out the radiator core externally as much as possible and replaced the thermostat but no luck. The cooling fan is operating normally as far as i can tell. Any suggestions of what the problem may be and what i can try next?
Any help would be greatly appreciated, thanks!
