Radiator Error Signal

[vramakr]

Hi Guys,

Need your help. My Radiator full service including hose change all done 8 months back. Suddenly now I have this radiotor error lamp flashing. Its intermitent, sometimes there and sometimes hilang. I brough to my regular mechanic and he tried high pressure check, bleeding and all....and confirmed that nothing is wrong with the radiotor. He ask me to test for few days and see. Now the light is up again. All my temparature sign in normal. Any advise guys? What can be wrong. Thx

Replace the coolant sensor and any sign of the coolant leak somewhere under the engine?

Thanks Mel279. I will check for the coolant sensor. There is no leak under the engine tho. Thx

Hi vramakr, have you managed to solve the radiator issue? would be great if you can share the findings. :67:

if there is no leak and water level is normal then try changing the coolant level sensor under the expansion tank (N42), very simple DIY
