A simple car/ engine type question.

Now this might possibly be the silliest question posted on here but here goes.
Earlier on I was stationary with the engine idling.
I had driven 10 miles.
It was raining.
I noticed steam rising off the bonnet.
My 1st thought was, engine is overheating but all dials etc were fine.
I cannot recall ever noticing that before.
Is it normal ??

Not a chance, have you seen the beginners forum for a start....

If the steam emanates from the edges of the bonnet and grille, the engine is overheating; if steam is given off over the entire wet panel of the bonnet, then it's completely usual and nothing to be concerned about.

There's a technical difference between engine overheating and undercooling, but I'll save that for another day.

Thanks.
It seemed to be off the actual panel.

It's normal if you have a Lotus Elise, as the radiator is mounted horizontally :wacko:

Used to cause great amusement in traffic jams in the wet ^_^ Mind you the bloody thing did overheat properly when the head gasket went :rolleyes:

Did you remember to unplug the kettle before you set off?

It happens in very specific circumstances. I remember it once when I was stuck in the queue for Newnham Park in 1994 to watch the MTB Worlds. Sudden rain shower, bonnet warm from sitting with no airflow.
