Hey guys, I just got done with my 113 head swap. I am having a couple of problems and one of them is with the cooling system. The guage is reading at 260 after only a couple minutes of running. I have no idea why its getting that hot. During the head swap I installed a brand new water pump, new 180 degree thermostat, flushed all the coolant out and installed a new temperature guage sending unit. Radiator is less than a year old also. Any ideas on why my car is getting that hot?

Next, there is a ticking noise of some sort. I cant tell if its an exhaust leak, or what. Heres a video I took: http://www.youtube.com/watch?v=_rvMzzfA0jU

Any help would be greatly appreciated.

The car is an 86 Iroc w/305 TPI.

check the simple things...take out the t-stat....of it still runs hot, check the pump.

do you still have the old temp sending unit? i would try that out and see if the readings are any different, you could have gotten a defective one

I dont have the old temp switch.

We were setting the timing today, and the fan didn't turn on. The temp was at 235-240, and the fan still didn't come on. So the fan not turning on is the main problem? Or what I'm trying to say is would the fan running/not running make the difference between it running too hot and not?

If not then I'll move on to the t-stat

My brother knew that when you check for codes that the fan would turn on, so he did that and the fan turned on. So what would cause the fan not to turn on when it gets that hot?

I am Rich's brother. I will add that the thermostat apperars to be working. Once the temp got around 200 coolant started flowing through the radiator and the temp went down to 180 for a little.
