Hi all,
I have an overheating problem with my B16A. the overheating only happened during idling in a massive jam. when I drive for long journey, it does not happen. I have checked the followings :
1. no boiling water on spare compartment when overheating or filled up 100% compartment
2. no sign of milky stain on engine oil cap
3. no white smoke
4. water level still same and no sign of reduced amount of water
5. took out the thermostat and problem still same..so thermostat was not the problem
6. water pump still very new
7. no sign of blown top head gasket
8. radiator cap still ok
9. radiator tank - double layer type
the only suspicious I have is the radiator tank..which could have been blocked as everytime I change out my radiator water, I can see rusty water coming out. I had this problem before but after servicing the radiator, it was ok for 6 months or so.
I believe the rusty water was due to bad engine block..i bought this engine from Japan (used). no matter how many times I clean my radiator, the flowing water out on the next service still will be rusty.
I have no overheating problem when travelling for 200 + KM at 140km/h to 180km/h speed.
also, one of my mechanic told me that VTEC engine must use the thermostat. is that true or is it good without thermostat?
Pls assist
