New Conundrum 2000 XJR Had Leak At The Reservoir. Removed And Replaced ,Then Had Fluid Leaking From Reservoir With Cap On And Tight. Changed Thermostat. Now Leaking From Overflow Tank And Still A Bit From Reservoir At Times ??? Any Help ?
Maybe you have a bad head gasket and your cooling system gets pressurised?
You have the air bleed and Atmospheric Catchment Tank plastic lines CROSSED or incorrectly connected!!
I Was Thinking The Same Thing But Hoping For Something Else
Continuing the discussion from Anti Freeze Leaking:
Tried To Swap But Hoses Are To Short To Do That And Took Pic’s prior To Removal
