Engine not getting up to temperature

bop1977

Hi all,

I have a problem with my car. It’s not getting up to temperature and the ac is blowing cold air.

The car is a 12 Skoda superb 2l 170bhp diesel with 160k on the clock.

The car in the last week or so hasn’t been getting up to temperature on my commute to work. I drive about 25 mins of mostly motorway to work and I don’t spare the whip.

A brief history of the car.
Full skoda history including dsg oil changes.
I had a water pump failure about 2 to 3 months ago and got the water pump and timing belt replaced.

Is there anything I can do or check before I bring it back to skoda? Could it be related to the water pump failure or is it a stuck/faulty thermostat?

Thanks in advance.

It does sound like thermostat stuck open.
Suppose you already check coolant level?

It's not too likely to be related to the water pump change. Have you checked your coolant level?

Edit: snap!

Hi. The coolant level is fine. It’s between the min and max level.

If the water pump was gone she’d almost certainly overheat.

I’ve had issues with the thermostat on a few occasions, once I changed it the problem was solved.

Low coolant level was a problem I had with the same symptoms as OP

I could and did top it up - which was a temporary fix. Head gasket was blown!

Any oil around the engine block or on the ground where you park?

Those engines have an electronic water pump too which cuts in and out as neccessary and can fail in the on position. That said, it could be anything.

Hi all, thanks for the replies.

A little update, I dropped it into a Skoda garage this morning. They took it for a test drive with their computer attached and checked everything. Their conclusion is the new water pump is too efficient at cooling the engine. They checked coolant, water pump and thermostat and everything came back normal.

I took the car back and the first thing I noticed when I got is was the engine oil temperature on the onboard computer was showing a temp of 90 degrees. Since I’ve been monitoring the engine temperature it has never gone above 80-81 degrees, so make of that what you will. Anyway thanks again for the replies and if anything changes I’ll post again.

That seems like an odd diagnosis. Was the pump replaced with a genuine part or some odd ball item. You would think that the pump operates within very specific parameters, pumping a specific amount of water over a specific time. What happens if you get a replacement pump that's "less efficient"?

Just my thoughts.
