Yellow Arrows in Engine Designer

[Trifler]

Do yellow arrows affect the service costs of the car (less room for mechanics to work) or are they merely to let the player know there isn't much room left?

[Pleb]

It's so show that the engine you're working on will fit in the car's engine bay. Once an arrow turns red, it's too big.

[WizzyThaMan]

Yeah, but that is not his question. He wonders when the arrow changes colour, it increases maintenance costs on an engine, or its only a warning that you should be keeping an eye on increasing as it might turn our bad for maintenance costs.

[Kubboz]

Well, it does not increase the maintenance costs on an engine directly, but it will affect the car's maintenance costs once the rest of stats are introduced.

Excellent. That's what I was thinking of. I shall endeavor for green arrows where possible then.
