Sounds like you have the same problem I recently had except I didn't stick gunky sh*t into my cooling system, my gu8 would run hot, few times got up to 110-115c, Wasn't losing coolant, but would pressurise the system after driving and not let the coolant back into the system and it would get stuck in the overflow tank..

The solution? A brand new radiator, Mine was over 70% blocked and this is only a 3 and a bit year old car mind you, Cooling specialist said they should be flushed every year or they get build up in them and clog up. Since I changed to new radiator, Running temp 86-92c with 92 being full noise and 600+ egt up a hill......

Mine also doesn't run a front ac fan.

This...... pull the rad, or i can do it. And either get it checked, will cost you $$$, for the check. Then they will either say, it fubar, more $$$, or you just bite the bullet and replace it anyway. Still $$$, but less than a check and new rad.
That is. If its just cooling issue you have. Not something more sinister. Then you will no choice but to get a professional to take it further. Compression and sniff test would be the first i would be doing.
