ENGINE LOW COOLANT ISSUE

Recommended Posts

 

Attached is photo of warning light that I got this morning almost as soon as I left home. (you can see the temp gauge is not even at half way level yet.

Additional information: 

1.       Red low coolant light goes on – then after 10-15 mins goes off.

2.       Water in Radiator seems ok – I top up a bit every 3-4 days – not a lot.

3.       No water leakage under car.

4.       New Radiator installed a few months ago.

5.       New Container next to radiator also installed.

6.       Temperature gauge always goes from stone cold to mid-way – and stays there.

7.       This week performance is now not good – some misfiring on start-up and also over certain speeds and under 20 MPH.

8.       Check engine performance amber warning lit up once – two days ago.

Any help appreciated as this is getting on my nerves now L

Welcome to the Club,Bradley.

 

Is your S Type a petrol or diesel engined car?

 

Does the temperature gauge move up quickly or slowly?

 

I will look around and see what I can find,

 

Regards

 

Peter.

Hi Bradley,

 

I believe that the correct place for the temperature gauge is halfway.  My temp gauge moves up very slowly [this is normal for a diesel engine] and then it sits there.  That tells me that there is no great problem with yours.

 

You should not have to top us that often, though, and Trevor has made a good suggestion.

 

On the amber light - check engine performance - a OBD2 code reader would be useful and you could get one for under 30 euros by looking around on eBay, if you have not already got one. [i have just changed some money into euros so I know the exchange rate at the moment  --  A week in Galway has been booked for June] 

 

I have seen quite a few posts on red light coming on saying low coolant, some of which have been due to a minor leak or a faulty sensor. However you had new coolant parts [rad and reservoir] fitted, so it is possible that a hose is not tight enough somewhere.

 

Follow what Trevor has suggested and see the result.

 

Regards,

 

Peter.

You have just described the exact same symptoms I've had over the past six months...I had the engine pressure tested because I suspected head gasket issues, but was assured it was ok. But last week (after three months of constant motorway driving if 110 miles a day) I had a puff of grey smoke and a misfire ...Then oil all over my drive! Currently looking to get it reliably repaired!
