But isn't that what the surge tank is supposed to accomplish? Do I really need both of these?

Last night I filled the tank and let the engine warm up until the thermostat opened up and started to flow. It burped twice and then flowed nicely. I put the cap on and went for a drive. It still spiked to over 110C and stayed there for a while. By that time the oil temp was at 95C and then the water temp went down to 65C and seemed to stick. I was running about 4500RPM so I wonder if the lower hoses are collapsing?

Tonight I might just try to duct tape a liter coke bottle to the inside somewhere and see if that helps.

I also turned off the inside fan and it didn't change temp.

I'm going to leave it with my mechanic on Friday so he can drive it to see what it does, fully drain the system and pressure/flow test the radiator.
