steamy radiator

starting to get quite a lot of steam from the radiator when its raining - its not a leak as water level hasnt changed. Obviously its water evapourating off the surface, but just curious as to why the behaviour seems to increased dramatically recently? are there any drain holes that could have become blocked?

Its rained alot more recently

worked it out… water was pooling in the radiator while the car was parked up… once the rad was up to temp - presto - steam-o-rama

whats changed recently? havent been parking under cover…

I thought you got it in the past reply…
