So to keep them going here's mine. I have a 91 crx si stock d16. On my way to work a few day ago I was late so I was going fast and at higher rpms. I noticed my temp gauge 3/4 high on the way back at low rpms and crusing speed it was normal. That day I changed the thermostat and flushed the radiator. Drove today to work and fine, on the way back y fast to se and temp started slowly climbing. I did an oil change this week and I didn't see when I camback any leaking fluids of any kind. The overflow tank was boiling and filled up and both radiator hoses were boiling hot as well. I'm thinking a blockage someware in the system or water pump issues. But only happened at high rpms above 3500. Also blown head gasket hopefully not but still. Fans work good as well. Any imput or tips or any kind of info will be great.

 

you might still have air pockets in the cooling system...!!!

 

Probably, any tips on how to clear then never done thhat before
