Hi Im David, thanks for visiting the site. First things first, did you bleed the air out of the system after you replaced the hoses and thermostat?

Customer: replied 2 months ago.
is that by the vehicle running with coolant reservoir cap off?
Expert:  david craig replied 2 months ago.

and squeezing the hoses over and over and over until you see no bubbles coming out. and yuo keep the system full while doing so

Customer: replied 2 months ago.

Expert:  david craig replied 2 months ago.

with the vehicle running and up to temp make sure the upper and lower radiator hoses are equally hot.

Customer: replied 2 months ago.
Yea there both hot... it takes awhile then they start to heat up bout the same
Expert:  david craig replied 2 months ago.

are your fans working?

Customer: replied 2 months ago.
Yea they blowing good
Customer: replied 2 months ago.
Coolant is bubbling then eventually it starts running hot
Expert:  david craig replied 2 months ago.

ok, you need to have a block test done to see if there is combustion gases getting into the coolant

Customer: replied 2 months ago.
I had a shop do one they drill a bolt out of the thermostat housing for when I changed it a bolt broke off. They did a pressure test I believe and said the block was giving a different reading or something like that. Then they called back this morning and said I had a cracked head gasket
Expert:  david craig replied 2 months ago.

a cracked head? or a blown head gasket?

Expert:  david craig replied 2 months ago.

they did a block test with the blue fluid ?

Expert:  david craig replied 2 months ago.

im not talking about a pressure test

Customer: replied 2 months ago.
Ooooh ok Nall I done got it! They said pressure. Is that something I can buy? I'm hesitant to drive it and cause more damage.
Expert:  david craig replied 2 months ago.

you can buy it online, not sure if a part store would have it.

Customer: replied 2 months ago.
Ok
Expert:  david craig replied 2 months ago.

you can try autozone

Expert:  david craig replied 2 months ago.

hows it going?

Customer: replied 2 months ago.
Ima just put another motor in it I guess. Head Gasket work is expensive in Richmond, Va....2300! I found a motor and mechanic to put it in for 3000. What do you think??
Expert:  david craig replied 2 months ago.

If the engine failed the block test and combustion gases are getting into the coolant, verifying the head gaskets being the problem then yes, thats a decent deal.
