blazer overheating please help

Ok I just recently replaced the intake manifold gaskets on my 98 blazer. Heat worked before hand but smelled like antifreeze in the cab when on. After fixing gaskets and flushing coolant sytem I have had no heat at all. No problem other than that until now. I was driving today and the temp guage started to rise. Needed gas anyway so I stopped at the gas station and checked the overflow bottle which was empty but could not see anythin leaking anywhere. Went in o get some water and when I came back out there was coolant sprayed all over the air intake an drivers side of the engine bay. So I poured the water in and instantly temp went back to normal but started to rise again as I was driving home from the gas station. So I popped the hood when I get home and to no avail I can't see anywhere that it can be leaking from and both heater hoses are hot so I don't think that is the issue but I have no idea as I'm not very familiar with this truck. I have only had it for two months. Any help would be greatly appreciated as I really have no idea where to even start looking for the problem at this point.

Sounds like a leak some place.
Get a pressure tester on it.
And check for leaks cold warm and hot.
When filling up system always remove rad cap and make sure rad is full.
But only remove it cold not hot.
When system is open the heater hose/heatercore has to have air bleed out of it.
