Hopefully i can help..
What Model / Engine / Year of Vauxhall do you have?
I note you say you have leak? do you know where roughly this occurs under the car or on the engine? or is it actually leaking or overflowing from the expenasion tank itself?
Have you had overheating issues with the car?
Vauxhall zafira. 2.0 diesel 56 reg see no leak...or no overflowing. But coolest level goes done an inch. No overheating issues. No leaks I can see under car. No overflow in engine. Put cap securely and also replaced it...still coolant goes down
Hi..there thanks for your reply..
Ok..normally with any sort of coolant loss there arent too many places coolant can be lost..either there is a leaks externally / or a leak internally / evaporating due to faulty cap which isnt really common for these caps to do that.the systems self bleeding so air pockets shouldnt be and issue.. If its a leak externally then depending on the nature of the leak wether it crops up under engine hot conditions when housing expand or under normal cold sometimes can be spotted on the ground or leaves a powder residue of the antifreeze around areas of the coolant system where the leaks exiting from..so certainly have re-check/trace the coolant circuit,pipe work or housings,radiator for evidence of that....the best course of action really is to have the system artificially apply pressure to the cooling system using a special coolant system pressure tester/guage in place of the expansion/radiator cap..once the system is pressurized as per the psi stated on the cap then they can go around the whole coolant system looking for the leak if there is one..it will also tell you wehter the system is indeed loosing pressure or not..so that would be something to maybe have done here..However if your car is fitted with Automatic gearbox..these cars have a cooler radiator which is part of the main radiator and can be known to fail and cause coolant to travel into the gearbox via its oil cooler lines potentially damaging the gearbox internally..so as above there are few checks and test to carry out..also dont forget to check within the footwells incase the heater matrix is leaking..I do hope this helps...if you require to ask anything further then please continue before you rate
My car us a manual. There is nothing under the engine or near the coolant tank.
are you saying that the heater inside the car could also be linked. The heater in the car is not very good. And doesn't really gave full power.... is that linked toooo
if so how can I check.
I don't want to keep going to car garage to get them to check as it costly and from messages on Internet it appears even after the checks garages still normally have no answer.... please give me details instructions on how I can check the heater issue if it's related....
or how I can check internal leak. The engine has a proper cover.... should I somehow look at that. I have had it checks and I do not think that the coolant tank or pipes are at fault otherwise in the service they would have found out... especially since I asked them to check the coolant issue....
The heater system has a heater matrix
