I drive a 90 300ce.

It is 105 degree today. In where I live, climate temp above 100f is nothing. On a hot day like this, My water temp is constantly above 100, it runs even hotter sometimes. I used to worry.

When I went through the debug processes and all the components, I found the prior owner of my 300ce modified the thermostat keeping it stuck open. I put in a new 87 degree thermostat, however makes no change.

I simply take it as normal now.
