Hose blows

I drove my truck up into the hills (of Hollywood) on a really hotbday and when I stopped the big hose leading into the Pleneum (if that's what it is called) blew up creating a huge steam cloud. I thought my truck was on fire for a minute.
I fixed it with a steak knife cutting the end off that blew and adding water, which got me home. Driving home the temp went way up then stabilized at the middle.

Generally, My truck seems to run hot... It always feels crazy hot. But I have not done the fix on the gauge, and the stock gauge just stays in the middle.

I have read lots of the overheating threads and threads that talk about things close to this, but nothing exactly like this blown hose.

1993 nas 110 75k miles seems to have endless problems

Any thoughts where to start? Thanks in advance

Old hose? I would start by changing them all out. It's a lot cheaper than a new head gasket and all the involved machining.

While your at the cooling hoses, don't forget hoses to the heater matrix as well. Is it time to rod out the radiator?

Ok. Yeah, the hoses do appear original. I was going to order a full set.

Is there a way to tell if a radiator is worn out? I am sure it is original too.

Twenty years old.... I would just replace all the hoses, the radiator, thermostat and fan viscous unit.

Completely agree. My truck was running hot at around-town speeds. The radiator fins would crumble when you touched them and the whole system looked original. I replaced every hose in the engine compartment, radiator, fan clutch, thermostat and sensors. The water pump is newer as well. Problem solved and it's nice knowing that all cooling components are new and solid.

Great idea to baseline the cooling. Hoses, water pump, fan clutch, radiator, radiator cap if its not new, replace it. It is not that expensive (less than a grand in parts). I run a 180 degree thermostat as well. If the sensors are not acting up (easy to check) I would leave them.
