Where socket goes on the bolt is stripped. need to remove?
My thermostat housing is cracked on my 1996 police interceptor, I did not realize this until i installed the new o ring gasket with the thermostat. when I removed and re-installed the gasket three times wondering why the housing was still leaking, AND after over tourqing the bolt and stipping the head where the socket goes i discovered a small crack where the housing mounts to the block. Can anyone help with ideas how to remove the bolt, the threads are fine. the size is 10 mm, go figure...

Re: where socket goes on the bolt is stripped. need to...
You can try this if you're brave enough.........find a socket smaller then the one you used originally to strip the head....using a hammer...pound the new socket down on the bolt head.....or you can go to yoru favorite parts store, and buy a set of EZ OUTS, or EZ OFFS....they do about the smae thing but you won't destroy the socket taking hte bolt out.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Notorious for intake leaks, the composite plastic intakes crack and leak coolant-as to the lack of power, you mght have overheated it and done some damage to the engine. There was a recall (information below) for the 4.6 for the intake-the overheating and lack of power means you should at least have compression checked and go from there-you may have bad head gaskets or worse. Do a compression test before you do anything else.
Ford Motor Company will extend the recall (01M02) on
4.6L V8 equipped vehicles with plastic intake manifolds. Some of the
composite intake manifolds used on 4.6L SOHC engines may develop fatigue
cracks at the coolant crossover duct. This condition could result in
engine coolant leakage which, if not serviced, may cause engine
overheating. Complete loss of coolant may result in engine damage or

Do not loosen radiator drain **** with system hot and pressurized. Serious burns from coolant can occur.
Do not waste reusable coolant. If solution is clean, drain coolant
into a clean container for reuse. If thermostat is being replaced, be
sure that replacement is specified thermostat for vehicle model and
engine type. Instructions
Locate the Cherokee's thermostat intake housing by following
the top radiator hose to the engine. The hose connects to the thermostat
intake. A second, smaller hose connects to the left side of the
radiator hose. This is a bypass hose for the heater.
Remove the two bolts that secure the Cherokee's thermostat
intake housing to the engine with a socket and ratchet and lift the
intake upward to drain the coolant in the hose back into the radiator.
Remove the gasket and the thermostat from the engine and
discard them. Wipe the mating surfaces of the thermostat intake housing
and the engine off with a clean towel.
Place the new thermostat, spring down, into the engine and place the thermostat gasket over the thermostat.
Place the thermostat intake housing onto the thermostat
gasket. Thread the bolts into the thermostat intake by hand to avoid
cross-threading the bolts and then tighten them using a socket and
Clean mating areas of timing chain cover and thermostat housing.
Install thermostat (spring side down) into recessed machined groove on timing chain cover.
Position thermostat housing on timing chain cover.
Install two housing-to-timing chain cover bolts. Tighten bolts to 115 inch lbs. (13 Nm).
Housing must be tightened evenly and thermostat must be centered
into recessed groove in timing chain cover. If not, it may result in a
cracked housing, damaged timing chain cover threads or coolant leaks.
Install lower radiator hose on thermostat housing.
Under the radiator hose that meets the top of the engine
under the throttlebody if you follow the heater hose from firewall on
the driverside toward the engine it goes to the thermostat housing.
To get to the thermostat you need to remove air cleaner box assembly
from the throttle body and move it out of the way.
Next, remove the nut at the throttle body that holds the steel tube
that goes to the heater hose, remove all hoses that connect to this
tube and raise it out of the way.
Remove the steel line that goes to the radiator surge tank from the
Now the fun part. With a 13MM box end wrench, loosen the lower bolt from
the thermostat housing. A 13 mm socket will remove the top bolt.
Remove the thermostat cover and remove the thermostat.
Reverse to install.
can say the 2003 APK 2.0L engines thermostat is located almost vertically behind the alternator, for the job you'll need sockets 10mm and the elbow joint extension for the lower bolt on the thermostat housing. the jobs a little fiddly but made easy with the elbow joint. care is to be taken when retentioning the plastic thermo housing as it easly breaks and a replacement isnt cheap So just use common sense when re-tightening others report using the TDI thermostat as its cheaper
You will need a 1/2" socket with ratchet, and a 1/2" wrench for the actual removal of the thermostat housing. First, remove the air duct from the air filter housing and the air intake connection to the engine. Set aside. Next, remove the upper radiator hose from where it connects to the engine by loosening the hose clamp. At the other end of this part where the hose was removed from is the "L" shape that houses the thermostat and bolts to the engine. This part (housing) has two bolts. The top bolt will require the use of an extension on your ratchet which you will need to insert between the water bypass pipe and the exhaust heat shield before coupling with the 1/2" socket. Loosen the top bolt. The bottom bolt will require the use of the 1/2" wrench, as the socket will not fit due to the location of the heat shield. NOTE: the bottom bolt only needs to be LOOSENED and not removed, as the housing has an open "C" at the lower bolt location allowing the housing to pivot upward from that bolt. After removing the top bolt and loosening the lower bolt, you can pivot the "pipe" end of the housing downward and carefully maneuver the housing out of its location. You should now see the thermostat.
Clean surfaces of the engine and housing well. Insert the new thermostat with the "spring" into the engine and the "bell" outward. Be sure the seal is seated properly into its socket in the engine. Position the housing carefully, making sure not to move the thermostat out of position. Reassembly is the reverse of removal.
In my case, I did not use any gasket seal. The thermostat has a rubber seal on it which works well on its own. Adding gasket seal may make removing the housing in the future more difficult
