Is it normal to smell a bit of coolant from the radiator cap,
I think it is almost new as it was replaced on my last service by my mechanic 5,000 km ago.
Does the radiator cap vent a small amount of pressure to the atmosphere or should i have no smell whatsoever and my cap is not sealing properly.
Also when i check inside my overflow bottle after the car has warmed up i see some residual bubbles around the edges of the overflow bottle, not bubbling, just some bubbles floating on top in small clusters.
Is this just a normal reaction to the coolant expanding and being sloshed around or do i have air entering my system and being pushed out.
I just want to make sure i don't have an issue. the colour of the coolant is bright green and car is not overheating.
if anyone has looked inside their overflow and saw small bubbles floating around the top could you reply,
Would be good to check.
Car is an R34 GTT
Thanks
