Diagnose if this is normal or not...

[ThriftyFifty]

Since last week, I noticed that on turning off the engine after a drive something beyond the normal begins to occur. It doesn't occur EVERY time.

 

Ticking is standard, but this is very strange.

 

Symptoms:

 

- Coolant res is bubbling and spluttering

- Weird whining noise from the engine bay

 

At point of turning off:

 

- The engine temp readout is 1/3 of the gauge which is normal

 

If left sitting idle (engine on)

 

- It will reach near the top of the temp gauge over 10-15 minutes (this could be normal?)

 

If driving it

 

- Completely normal/responsive, temp gauge reads 1/3 all the time (I let the car heat up before I take it out for a drive)

 

A picture says a thousand words... a video will hopefully say a million

At least your engine bay is nice and clean Have you checked you dont have an air lock and your temp should not get to near the top as the fan should bring it back down before that

Sounds like your fan motors are not kicking in mate.

Yeah the bay is spotless, apart from my resident cat stuck somewhere.

 

Alex, would that explain the weird noises too though? Would the fan run while driving as well as idle? Because normal driving it stays cool (according to temp readout).

 

Once the engine goes off, the weird noises start.

 

Also, how easy to install one of these - Or how costly to install one if I'm not going to DIY it?
