Ve coolant disappearing??

[kizza50]

2006 ve v, had a slow Leak from heater hoses, so I replaced them, coolant level was fine for about 2 months now it's going down about a liter every month, no signs of leaks anywhere n no leaks onto the floor..... Could the cap be the issue?? If so And the coolant isnt going back into the overflow, wouldn't it just be on the floor??

Check you oil too and see how it looks. Car overheating? Could be evaporation from the Cap. Also bleed the system as you may have huge air pockets after changing the hoses.

Best to take it to a radiator repair work shop where they can give the cooling system a pressure check. At the rate of a liter per month, if it were to be leaking externally, it would be evaporating before it reached the ground, making it a bit hard to detect though a 'tell tale' residue might be visible. Personally, I would simply put some cooling system sealer in and that should stop the leak, if that is what the problem is.

Might top it up n change the cap see how I go,

could be a faulty sensor as well

How would a faulty sensor result in coolant loss?

I was pondering the exact question, lol this may be a silly gesture but I could actually smell coolant burning like it was it was leaknf on the exhaust manifold shielding but from the cap exactly.

my missus had the same problem and it was due to a sensor issue, how it would result in coolant loss i have no idea

Do you men it had a leak at the temp sender sensor ?

some sort of sensor associated with coolant regulation
