hi all just wondering if anyone can help my vx sintra 2.2dti is losing coolant and i dont /cant find the cause.

I replaced the water pump as the old pump was failing there was a slight leak from the old pump, so replaced pump and pump gasket, checked all was ok didnt notice any leaks,then 4 days later saw the temp gauge was higher than normal when i checked the header tank on water so i put about 2 litres of water in and all was fine for about 3 days,then need to put water in it again every morning now i check the water level and some days it needs a top up some days it dont.


i have no oil/water mixing and no pressurizing in the cooling system all hoses seam to be ok and for the life of me i cant find a leak but the water has to be going some where dose anybody have any ideas? cos this has fried my brain it is the same engine as used in the omegas and vectras.

thanks for taking the time to read
