Yes there are cooling system hoses under the intake, here are instructions to remove the intake.

Instructions

  1. Remove the Intake Manifold
    • 1Drain the cooling system and relieve the pressure in the fuel system. Disconnect the negative battery cable, the air intake duct, the IAC valve connectors, the throttle position sensor and switch connectors, and the EGR solenoid valve.
    • 2Pull the EVAP canister vacuum and purge hoses, the vacuum hoses from the EVAP, the brake cylinder, pressure regulator and EGR tube. Tag and disconnect the spark plug wires. Remove the distributor cap.
    • 3. Take out the three left bank injector connectors, the thermal transmitter, the ground harness, breather pipe and the upper manifold. Disconnect the fuel feed and return lines and plug them with golf tees to prevent fuel spillage.
    • 4Locate the right injector harness connectors and disconnect them as well as the fuel rail and injectors. Remove the coolant temperature switch harness connector and the water hose from the thermostat.
    • 5Loose the bolts on the lower manifold in sequence. Remove the bolts and left the intake manifold from the engine. Remove the gasket and discard it.
    • 6Clean the mating surfaces by scraping the old gasket material and carbon deposits. Clean the surfaces with solvent and inspect them for damage.
    Install the Intake Manifold
    • 7Put a new gasket in place and install the lower intake manifold to the engine. Tighten the bolts in sequence as follows: first pass-35 inch pounds; second pass-78 inch pounds and third pass 70 to 84 inch pounds.
    • 8Connect the ECT sensor connector, the fuel supply manifold and the right bank injector connectors. Connect the fuel lines and then install the upper intake manifold. Put the breather pipe in position.
    • 9Install the intake manifold ground cable, the thermal transmitter, the left bank injector connectors and the distributor. Reconnect the spark plug wires.
    • 10Continue reconnecting all the components, reversing the order in which they were removed. Connect the negative battery cable to the terminal. Refill the cooling system with the appropriate coolant.
    • 11Start the engine. Check for fuel or vacuum leaks.

SOURCE: coolant leak from upper radiator hose where it meets engine

thermistate housing is the place you refer to it fuction is to hold a thermastate to open and close water flow at 150 to 190 degree according to car spectif the thermaste sticks it causes overheating and can blow the thermastate gasget, the tole cost is about 30$ at most for the thermastate and gasget...now many other things can cause a car to over heat and cause a hose leak and somtimes it is simple to just tighten the hiose clamp at the thrmastate and problem sovled see a water leak causes the radiator to lose presure and thus with out a sealed tight water cooling system the boiling point of water is lower and thus the car over heats when in doubt stop by the local gas station and have a tech take a quick look as it could be simple as the hose clamp difficult as a therm,astate but do not let it go to warp a head gasket as this blown headgasket is what is the end results of running a car to hot

How do I flush the radiator
Removing the drain plug and just letting old coolant drain out and then refilling doesn't really flush it out. It only drains what is in the radiator and it doesn't circulate and flush what is in the engine and heater core.
Take radiator cap off, then take top radiator hose off where it comnects to the radiator..only disconnect that side of the radiator hose aim end of hose downwards and leave it there. Take a wet rag and push it into the radiator where the hose was connected..you don't want to push it in so far you have trouble removing after flushing...the wet rag is just to limit the amount of water that will come out of radiator where hose is no longer attached..crank car and coolant will start to slowly come out the vend of radiator hose aimed downward...have a hose or 4 or 5gallons of water...right after you crank the car pour the water or befilling the radiator with the hose...you want to keep the water going in the radiator as to keep it fulI...replace what is coming out of radiator hose...continue to add water until what is coming out of the radiator hose is clear water.. this way the water is circulating through the entire cooling system and engine. When water is coming out clean...turn car off remove rag from radiator and reconnecupper radiator hose..the drainplug is at the bottom of the radiator on the side of radiator that is on the drivers side of the car....remove drain plug and drain water left in radiator..replace drain plug and crank vehicle and fill radiator with coolant recommended for your vehicle... Sounds more complicated than it really is..other option take to a repair shop and have them flush with machine..usually around 100 bucks at ashop..Iif you have any questions Iwill be glad to answer..

How do i change the radiator fluid?
Most radiators have a drain plug on the bottom tank the engine block also has a drain plug . Remove the radiator cap ,open both drains ,let all the coolant run out, if there is no radiator plug remove the lower hose , remove the heater demister hoses, with the heater control on hot flush out all the coolant from the heater radiator. with a garden hose, till the water runs clean, tighten the radiator plug or re fit the hose,put a garden hose into the radiator and flush out till the water at the block plug runs clean ,refit the heater hoses, refit the block plug, fill the radiator from the hose leave the cap off , If it has a overflow tank clean and flush it. start and run engine for 5 minutes top up radiator if needed . stop engine and drain out all water. most important that all old coolant is drained out, only buy the best coolant you can . If you make up your own use only distilled water. keep some to top up with never mix with another brand. Fill radiator with coolant top up over flow tank, run engine top up coolant as needed, refit radiator cap run for another 10 minutes check for leaks,

My 1998 jimmy has always leaked antifreeze but the last month it has got bad to were i have to fill it up everyday
You need to get or rent a coolant system tester and identify where it is leaking from. They are very simple to use. You just remove your radiator cap and install the tester and pump up the cooling system and then you watch for where the coolant is coming from. Look closely at your water pump, intake manifold gasket, radiator, heater hose coupler on the intake manifold, and coolant hoses. Those are all the common leak areas.

My 1999 blazer is leaking antifreeze. can't really tell from where but it does not always leak. most of the time it is over the weekend when I am not driving it.
You can buy or possibly rent a coolant system tester which pumps air into it to help locate leaks. Very simple to use. You just remove your radiator cap and replace it with the tester and pump it up to the PSI listed on your radiator cap and watch for leaks. I would pay close attention to the water pump and intake manifold gaskets. It could be something as simple as a loose radiator hose clamp. It is common for intake manifolds to leak and they expand when hot and contract when cool so the leak is more noticable after sitting. Look on top of the engine around your intake manifold and your heater hose for coolant or a chalky like residue which can form from coolant leaking. Your water pump has what is called a weep hole on it which will be located behind the pulley close to the shaft. You may need to use a mirror to see it. If coolant is leaking out of it the water pump will need replaced.

Ok. guys. i am losing coolant. it is not showing up in the oil and i have no external leaks. i did replace the head gasket and all associated gaskets about two months ago. also have changed the upper and...
If the coolant is leaking at the head gasket or the intake manifold gasket slowly, then new gaskets will have to be installed. The bubbles coming up is a bad sign that the seal of the coolant system is bad or it's overheating the coolant to the point that it boils over.

The overheating may be due to air or vapor in the cooling system not allowing fluid to flow freely.

Did you put a 50/50 concentration of coolant to water into the cooling system?

Also, check the fan to see if it is turning on when the car is at operating temperature at idle.

May need to be flushed out and new coolant installed to increase cooling efficiency.

Good luck on this repair.

Heater not blowing heat only cold
Check the coolant level. It is common for the intake gaskets to leak causing the coolant level to drop. The first thing to stop working when the coolant gets low is the heater. Top off the coolant and determine where you are leaking coolant whether it be the intake gaskets, hoses, radiator, water pump, etc.

If the coolant is full what does the temp gauge say? Once the vehicle is warmed up it should read around the 200 degree mark. If its below 190 than the t-stat is stuck open. Replace the thermostat.

If both of those are fine and the coolant looks like mud than your heater core is plugged. You can try back flushing it with a water hose. Remove both of the heater core hose and use a water hose to flush out the heater core. This may take several tries before you start to feel some heat.

Overheating Problem with 2003 Bonneville. I have
The one thing I would check first is the cooling fan a quick check is with engine running turn a/c on and see if radiator cooling fans are running, if they are then we know the the fan's are good, if they don't come on check voltage at cooling fan if you have voltage bad cooling fan, turn car and a/c off, start car again with a/c off and fan's should come on at about 220deg. if they don't come on disconnect coolant temp sensor fan should come on, more then likely bad coolant sensor, now if fan don't come on you'll need check check your radiator or have a radiator flush.

My lincoln ls v-8,is running hot after i changed the thermostat, & water pump what else could it be
Build up in the coolant system a faulty Sensor reporting that the engine is hot when it is not. You can try running a coolant flush through the system to remove that possible problem. If you are basing this overheating problem on coolant being forced out the over flow, do a compression check on the cylinders. If one or more of the cylinders is running extremely high compression you may have a faulty head gasket, cracked head or cracked block.
