We've checked for any signs of HG failure, but no, it isnt the HG. Can the termoswitch be the problem? (The thing that starts the vent when needed) After setting a manual switch for starting the vent, there are no longer such water blow offs.. if I dont start the vent, the temp gauge will raise up more and more, if I start it, it goes down.. but if its the termoswitch, how does it start up automatically sometimes when needed? (1 of 10 times)

there is 1 temp sensor screwed inside radiator, one in the block, and another one to send data to ecu

on my car i thought head gasket has gone when antifreeze suddenly start to disappear and couldnt see any leaks or hg failure symptoms, later found water pump was leaking

if you still cant see any leaks i would reccomend you to buy compression tester from local shop or something like this from ebay

So I need to change all 3 sensors? and check for leaks? How much do the sensors cost?
