Erol Posted April 4, 2008 Share Posted April 4, 2008 Dear Members, I have a 2002, 6 cylinder 2.5 lt petrol engine on my Freelander, Recently I have noticed a minor pressure build up in the header tank and the water level is unsteady. can this be a Cylinder gasket problem? There is no water in Oil engine runs perfectly and the temperature is normal. Please advice. Quote Link to comment Share on other sites More sharing options...
viorelluta Posted April 4, 2008 Share Posted April 4, 2008 Pressure in the cooling system is normal; coolant level fluctuation is also normal, as long as it stays between Min and Max levels. Keep an eye on: coolant level, the general aspect of both coolant and oil and engine temp. Quote Link to comment Share on other sites More sharing options...

The problem is that the cooland level rises up to the top of the header tank when engine is running, when the engine is stopped the level comes down to minI try to keep the level slight below the minimum as otherwise will over flow. Please advice best regards Erol Quote Link to comment Share on other sites More sharing options...

Please advice best regards Erol I can only guess you need to eliminate the air it might be in the cooling circuit... Quote Link to comment Share on other sites More sharing options...
Erol Posted April 7, 2008 Author Share Posted April 7, 2008 Thanks I will try, in the mean time I was adviced that there is a possibility of the thermostat been stuck. Quote Link to comment Share on other sites More sharing options...
viorelluta Posted April 8, 2008 Share Posted April 8, 2008 Thanks I will try, in the mean time I was adviced that there is a possibility of the thermostat been stuck. i think that if the thermostat gets stuck the engine temp will rise. or maybe it is not completely closed. yes, could be a cause Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 8, 2008 Share Posted April 8, 2008 If the stat was stuck it would either run cool (stuck open) or overheat (stuck shut). Quote Link to comment Share on other sites More sharing options...
jules Posted April 9, 2008 Share Posted April 9, 2008 Get the system compression tested if that doesnt show much the try the engine compression test for any head gasket problems. the oil and water don't necessarily always mix. May seam extreme but at least you will knock out one major component and can start checking other areas Quote Link to comment Share on other sites More sharing options...

No , the thermostat was 40 euros, I have replaced 6 sparking plugs, Oli and Air filters, water hoses and oil breather lines, with the labour charges all came to 704 Euros.
