b4 you start it today spin the clutch fan note how east it spins then warm it up and spin again there should be a noteable change,also another rad cap is needed or get the one you have pressure checked .

but that doesnt rule out that there is no heat, ill try to explain it again in detail.

Installed a clearwater head the other day, started up yesterday no issue's heated up normal
heat worked
didnt overheat.

I let it sit for around 4 hours til i got off work, went outside to start.
belt started squeaking bad.

then i started to drive it to my home. (less than a mile away)
i noticed that my heat was ice cold
temp gauge started to get past 215.

I got in my driveway and noticed that there was some coolant that sprayed out of the radiator cap. I checked for coolant level, it was good. I squeezed the upper rad hose and it was swollen, i grabbed the two hoses that go into the firewall and they were swollen. after sitting about 5 minutes they returned to a normal state.

Maybe the thermostat went out on me after i drove it the first time? and it wont open? both rad hoses are hot. but i dont see how any fans would not cause me to have heat.

im going to start with a new thermostat and new rad cap and see what happens from there

the heat problem could be a blend door problem ,keeping the motor cool is the no 1 factor first

You sure the belt is tight enough? If it is slipping on your water pump and it decreasing the efficiency of your pump not letting it circulate enough.

I'm going to tighten the belt, see what happens. Then go get a rad cap and thermostat. Hopefully that will do the trick.
The radiator was new in November and I don't think it's clogged. I'll keep updating as progress comtinues
