Steam from bonnet

[drucejnr]

Just noticed the last couple of days thanks to the rain that there's a bit of steam coming off the bonnet when it gets to temp... but I also noticed the same thing happened today even though there was no water on the car/it hasn't rained at all in the past ~12 hours.

I had all the cooling hoses, crack pipe, thermo housing, water pump etc changed when I had the engine swapped so could it be either lacking coolant or could my radiator be leaking?

just the rain evaporating off the hot bonnet??

thats what I initially thought but it happened today when there was no water present at all on the bonnet. Will monitor it over the week though

haha, that'll teach me for not reading your whole post :p

As soon as you notice it, pull over, pop the bonnet and have a look?

[drucejnr]

haha no worries

Did that as soon as I spotted it in the driveway and it just seemed to disappear... Again, I'll keep an eye on it because I've got no idea as to what it could be. All hoses and everything related to cooling is brand new

mk3 playing games, that's unusual.... haha, hope it's not a lead up to something critical.... keep one eye on that temp gauge man

yeah thats what I forgot to mention, the whole time its doing it the temps have been normal so 90 for coolant and around 100 for oil...

had a similar problem on my old S12 silvia

ended up being a super tiny oil leak dripping from my rocker cover into my exh manifold cover.

whenever a tiny drop of oil hit the cover, a small puff of smoke would come out of my bonnet.

could be something similar?

You did mention you needed a new hose for your washer jets…… its not slowly dripping water from the old hose onto your engine is it?? just a thought.

could be that because I did accidentally use them the other day but I doubt that the whole washer line is leaking and causing it; I've got whats left sitting in the rain tray away from harm. By the way, I'll text you to ask what time is good this week/weekend to come round and pick that up.

Finally discovered where the "steam" was coming from!
For those of you with foglights, you'd know that they get pretty pretty hot and in the wet, they do get a bit of water on the lens; it was just water on the foglight lens evaporating and being "sucked in/up" by the radiator fans.

crikey :/ I knew they got hot but would never have thought they'd produce enough steam to concern anyone! amazing that glass doesn't crack...

I think the only way they'd crack is if the temperature changed suddenly, like a good amount of water dropping on them after they've been on and hot for a while. Otherwise they should be fine.

ie in the rain? but obviously they'd be fine otherwise that'd be a bit useless, haha

lol, you're right...but if you have rain do you have fog?
