Why is my car running a little hot?
Engines can overheat for many reasons. In general, it’s because something’s wrong within the cooling system and heat isn’t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Why is my car running a little bit hot?

Why does my Golf Mk4 have an alternator workshop warning?
My wife reported that her 2001 MK4 Golf V6 4motion reported an “Alternator Workshop” warning the other day. I’ve just checked the voltages and the battery voltage is 11.8v which rises to aroud 13.4v when the engine is running. This doesn’t change if you rev above 2500rpm.
What happens if you have a bad alternator in your car?
The car won’t start at all. If the problem is a bad alternator, your car will slowly lose power. You’ll be driving down the road, your lights will dim, and you’ll lose power and die. If the problem is with your battery, then you’ll generally only have trouble starting your car since that’s the battery’s main function.
How to diagnose an alternator or electrical problem?

Why is my alternator low at 2500rpm?
This doesn’t change if you rev above 2500rpm. The battery voltage is a little low at 11.8v (probably because it’s not charging well/at all) but it does seems that the alternator is doing something as the voltage rises to 13.4v when the engine is running. Faulty voltage regulator, perhaps?
