Hi,My name is Tim,
I will do my best to assist you
does the truck run well?
has it ever been really hot?
tell me all you can
runs well never been really hot .problem started with hose leak.
small hose from top of engine
and,,you have replaced the radiator cap?
what is the lbs of the cap you installed
yes surge tank cap
does the coolant come out at the cap on the tank?
yes through overflow hose
where the capis located
or at 1
stand by please
lets do a couple of things here
sense the engine runs well and has never been hot
and,,you did work on the cooling system
first,,inspect the coolant tak
make sure it isnt damaged and the seal on the cap is sealing to it
you may just need to bleed the system
lets bleed it this way
1,you need to remove the radiator/reservoir cap when engine is cold
2-start the engine and let it idle
3-turn the heater on high
4-keep coolant on hand and add it as needed...some coolant may gush out with the air,so be careful
5-keep doing this until the engine is at operating tempeture,the heater is hot and the coolant in the radiator settles down
6-then install the cap
if it still does this,,
again,,check/replace that new cap
be sure to inspect the tank for damage
i dont think you have a problem with the engine like a blown head gasket,,,sense it doesnt get hot and the problem began by replacing a hose

yesterday mech bled system as you said i was there replaced cap
check that new cap..and the tank itself
if all is well..you may need to pressure test the cooling system to make sure you dont have a blown head gasket
these are the only things that could cause this problem
drove truck this morning .leaked a lot. what kind of damage would i be looking for
like where the rubber sealon the cap contacts the tank
make sure it seals tight
it is posible to get a bad new cap
again,,the things i have told you are the only things that would do this
Pressure Cap Testing Tools required ^ J24460-01 Cooling System Pressure Tester ^ J42401 Radiator Cap / Surge Tank Test AdapterPressure Cap Testing 1. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap is removed while the engine and radiator are still hot. Remove the pressure cap. 2. Wash the pressure cap sealing surface with water.
3. Use the J24460-01 (1) with J42401 (2) in order to test the pressure cap. 4. Test the pressure cap for the following conditions: ^ Pressure release when the J24460-01 exceeds the pressure rating of the pressure cap. ^ Maintain the rated pressure for at least 10 seconds. Note the rate of pressure loss. 5. Replace the pressure cap under the following conditions: ^ The pressure cap does not release pressure which exceeds the rated pressure of the cap. ^ The pressure cap does not hold the rated pressure.
ok i will check cap and tank.what if engine did get hot what would you check
the head gaskets
they may be blown
this would let the comp-ression of the engine blow into the cooling system,,
is this expensive
making it have too much pressure
yes..it will cost some money if it is the head gaskets
i will probably take it to the dealer where do you sugest
the dealer may be your best help
but..it wont be cheap
if you dotn work on your own truck
i would sugjest the dealer
they will have the tools to do all these tests
