It is a quick hose conecter . the conector needs to be replaced . not a easy job because they tend to break off in the engine . you may want to take it to a shop

Recently I replaced water pump and radiator checked out ok. Water is still leaking out.I have a 300 Chrysler 2005


There are many places that coolant can leak from, other than the water pump and radiator. As vehicles age, so do their components. Obviously, your water leak is elusive; otherwise it would be obvious where the leak is. If you can see coolant leaking onto the ground, then there are a few other things to check. Look for bypass pipes that may be on the engine. These can leak at joints. Also, heater hose connections can loosen or corrode, causing leaks. Radiator hose connections as well. Another common elusive leak in older vehicles is the heater core. When these leak, often they leak either onto the passenger side floorboard, or they may leak into the condensation tray for the A/C coil and just drain out onto the ground, leaving no other trace of where the leak came from. Lastly, engine blocks and cylinder heads have metal disks installed called freeze plugs. These are placed to prevent the casting from cracking should the coolant freeze and expand inside. These disks corrode and rust out over the years and can leak. Some are in areas that are not easily visible and can hide well.

My 1999 dodge caravan is still overheating. I have already replaced the thermostat and the water pump, also there is no heat. please help me someone!


Hi there.
Well you can either have a problem with either radiator outer {dust/dirt in outer core of radiator or clogged up inside were water goes, or soft hoses,blowen head gasket plus a few others ,but first go to garage to were you blow up your tyres and use the air hose and blow out the radiator core where the air goes in, 2 drain out radiator water and then refill with water at 1 ltr at a time and then check your info car book and find how much water the radiator takes ,if it dosent take all the ltrs then the radiator is blocked inside.
if engine runs rough missing etc then get your Head gasket checked out.
When you say no heat is that with heat on gauge or no heat from heater, as it could be heater blockage same as radiator core. So let me know how you get on.

My van is leaking antifreeze from somewhere by the firewall of the van not the radiator. Its the metal hose that has a hole in it but i can't figure out the name of these metal (aluminum)hoses.


The metal hose by the firewall is either your heater core inlet pipe or outlet pipe. These inlet and outlet pipes will develop leaks for a varity of reasons. If this is the source of your leak, you may want to replace the entire heater core which is much easier than trying to fix the leak. The attached link will help you.

Describe how to bypass a heater core in a 97 Dodge Dakota plz.


Easiest way to bypass a heater core is to disconnect both inlet and outlet hoses at the engine firewall. Install a right angle hose coupling in each hose. Then install a straight piece of hose to connect the two hoses.

Water leak under the intake manifold,1995 toyota 4 runner


There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

Water leaking out engine near front fire wall


Sounds like one of the connections to the heater core are leaking. Should be hoses connecting to the metal heater core pipes. The heater core is on the inside of the car with metal pipes going through the firewall to heater hoses.

200 2.0 jetta cooling system diagram. i have a leak on a metal hose that goes into block left side of engine. how do i fix?


The metal pipe you are talking about is a heater pipe. it carries coolant around the block. i would just buy a new pipe and replace the old one. if you use epoxy or something its probably going to leak. there is a bracket built into the pipe and its screwed to the heater hose flange on the side of the motor. once you remove the two nuts you should be able to take a prybar and pry it from the block. (Its just pushed into the block and sealed with an o-ring)
