Temp gauge spike after accelerating
My temp gauge started spiking real fast when coming to a stop then getting back on the gas. I flushed the sys. but still doing the same thing So here's where I'm at. I replaced both thermostats with 180 degree. I replaced the fan clutch because it was weak and new radiator cap. The first time I started it I bled the sys. and the temp still crept up slowly while idling so I cut it off thinking head gasket. So I got a block tester to see what would happen. I started it with cap off but the water would come out until the thermostats opened. I put the cap back until around 180. It released pressure but stayed at 180. I put the block tester on and it would start bubbling by itself. I left it on for 3 or 4 minutes and the liquid stayed blue. I done this 3 times so I'm thinking maybe head gasket not blown? I put the cap back on and let it idle for another 10 minutes or so and the temp stayed around 180. I let it cool down to hook everything up to take it on a test ride. After doing all that I top it off and start it up. I crack the bleeder just to make sure no air. The temp trys to creep up so I take the cap off. It cools back to 180. I top it off and put the cap back on and let it idle for a few minutes, still 180. I take it down the road at 60 come to a stop and turn around still 180. Head back and come to a stop. After I turn on my street It starts to heat up. Pull in my drive way and try to take off the cap. After getting it off and hot water coming out the temp goes back down to 180. So now what
