cooling systems are designed to run under pressure to raise the boiling point of the coolent. Your pressure cap should have a psi value on it. So when the system is pressurized, the hoses will feel firm.
Unless you had coolant in the oil? Why did you mess with removing the head? PITA job especially if done in the car.

I had bubble coming in radiator, so I was guessing it’s the head gasket:scratchchin

Do you think it's wise to use 160 t-stat??:headscratch:
Thanks for helping:bigthumbsup

is it tuned for a 160 stat? If not, whats the normal temp that its running? I'm sure it's always in the warm up mode if it's not tuned.
+1 about being under pressure and how it works.

I have no idea what the original tuning 160, 180 or either 195, do you advise to try 180 or 195?

By the way it's very hot and humid weather; it's like Florida summer time I guess:headscratch:

Car stock setting should be considered when you change the thermostat...try not to stray too far from stock setting or your computer will always thing its running cool and compensate. And yes, your hoses being pressurized is a good thing.

go with either a 180 or 195 t-stat.....

anything lower will cause additional problems.....
