Hi, Ive been having the same problem for a few months now but its getting worse so I brang it into a shop today. They are gonna check it out. They put the laser to the block and it was 230 and the thermostat housing was 205 and radiator was 230. Also the coolant was literally boiling out of the resivor since it was so hot. So thats where my coolant is going. Within the last 6 months I did new radiator, radiator cap, fan switch, honda oem thermostat. What do you think they will come up with as the problem. I have to get it fixed before I blow the head.

Do you
have the same problem?

You may have done that already. Have them do a leak down test to confirm.

Ive had a leak down test I believe at another shop that claimed it was fine. They said they checked the cyclinders for water is exactly what they told me. IS this a leak down. Also oil and coolant are fine by looking at it. No smoke

T stat is open but the rad is hot from possible circulation issue or super hot gases from a blown head gasket

As I have stated several times, it may be a head gasket. You need to have this verified first before moving forward.

They can do a chemical test of the radiator gasses, this will show any exhaust in the radiator, if so the gasket will be at fault, this is a simple and quick test that they can do.

Well its a blown head gasket. Im just gonna try some head gasket sealer to get me by temp. They found gases in coolant they said it turned yellow on the head gasket test. Any suggestions on head gasket stuff in the bottles. I saw one at wallmart I think called k&w its an orange can.
