codytotheh Posted April 5, 2009 Author Share Posted April 5, 2009 so any ideas on what is wrong ?? Quote Link to comment Share on other sites More sharing options...
oldschool Posted April 5, 2009 Share Posted April 5, 2009 It might be your water line to your turbo. the turbo is water cooled from your radiator. Quote Link to comment Share on other sites More sharing options...
codytotheh Posted April 5, 2009 Author Share Posted April 5, 2009 dont think its the turbo line, you can see that in the picture, it actually looks to be leaking from under the intake Mani..... Quote Link to comment Share on other sites More sharing options...
mdjdc Posted April 5, 2009 Share Posted April 5, 2009 There is a hose under the intake that preheats the throttle body. I had a very similar situation and that hose had broken. A real PIA to get to. From the front of the engine look under the intake and you can see the hos I am talking about. I'll bet you it is the culprit. The easiest way to replace it is by unbolting the intake and lifting it up. Remember to drain the system or you will get coolant into the cylinders and hydrolock the motor. The hose is small and I just replaced it with fuel line of the appropriate diameter. The other possibility is the cooling line to the turbo. It is on the front of the turbo, but if it is leaking on the bottom, it will pour coolant on the top of the block. Check that one too. It is on the passengers side of the intake to the turbo. Normal size hose. I'm thinking that it is most likely the first one though. Good luck Quote Link to comment Share on other sites More sharing options...
4x4_Welder Posted April 5, 2009 Share Posted April 5, 2009 Yup, throttle body line. I replaced mine with 1/4" fuel hose. I can tell you for a fact that that is a pain to even find, since they are so buried and usually only leak under throttle. You might want to go to a shop and have them put some dye in the coolant so you can see the source. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted April 5, 2009 Share Posted April 5, 2009 Yup, throttle body line. I replaced mine with 1/4" fuel hose. The hose is small and I just replaced it with fuel line of the appropriate diameter. The ethylene in the coolant will seep through the fuel line within a few years time. Additionally it is not meant to be exposed to constant 200+ degree heat. I used it, then saw detrimental long term effects. You really should use Coolant hose Carquest carries actual Coolant/heater hose in sizes from 1/4 on up. If you are really hard up, use Trans cooler line. It is made for the heat at least Quote Link to comment Share on other sites More sharing options...
codytotheh Posted April 5, 2009 Author Share Posted April 5, 2009 so best Course of action :: Yank intake manifold, replace that hose 1/4" heater hose (how long), clean up old intake gaskets put on new ones, drive away happy..... "? Quote Link to comment Share on other sites More sharing options...
Turbone Posted April 5, 2009 Share Posted April 5, 2009 That little hose can be removed without lifting the intake. It takes a pair of longnosed pliers tho, preferably with a angle. The hose only has a spring clamp on the end under the intake. The other end is easy. It might be your water line to your turbo. the turbo is water cooled from your radiator. The turbo gets cooled from the rad, true. But the line comes from the water inlet on the thermostat housing. Quote Link to comment Share on other sites More sharing options...
DaveT Posted April 6, 2009 Share Posted April 6, 2009 The ethylene in the coolant will seep through the fuel line within a few years time. Additionally it is not meant to be exposed to constant 200+ degree heat. I used it, then saw detrimental long term effects. You really should use Coolant hose +1 to that. Been there, done that. Almost fried an engine when the fuel line failed only a year or so later. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted April 6, 2009 Share Posted April 6, 2009 That "little hose" is on the front to the engine, not behind the intake manifold and throttle body. If not the turbo coolant line (might want to replace it while you are messing around; I have had several literally shatter on me ), then either the coolant manifold (runs directly behind the intake manifold, bolting to both ends hear the head) or where either the CTS or thermo-vacuum-valve screw into the coolant manifold.
