Leaking Water Hose (not radiator hose)

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.

It sure sounds like the heater core, especially if you have water leaking inside the cabin. The two heater hoses only go from the engine to the firewall, and do not go into or through the firewall. They connect to the heater core right at the firewall.
Check carefully around the back side of the engine and the heater hoses, though. If a freeze plug is leaking, water will be dripping off the bottom of the engine. If it is leaking before the firewall, that would not be the heater core.

You should be able to trace the heater hose from the Firewall back to the engine. That is one possibilty. Sometimes depending on how water circulates in an engine, the intake manifold can distribute water and a leaking gasket will let the water out.

There are tools which can be borrowed from an Autoparts store for a returnable deposit. You would want a Radiator pressure tester which will alow you to test the engine when it is cold and force water out of the leak.

It sounds like the evaporator drain tube is blocked or came off the duct inside, pull the carpet back and locate the rubber drain hose on the bottom of the evaporator housing, the hose should go through the firewall so water can drain out, the hose may have become disconnected before the firewall or it come off at the evap housing, pull the hose of the evaporator if water comes out make sure the hose goes out through the firewall and is not clogged.

It sounds like you're looking at the heater core water lines. These connect to the heater core supply and return inlet and outlet pipes to bring hot coolant into the cabin for heat and windshield deicing.

The heater core is a mini radiator and operates on the exact same principles as the radiator does. The heater core is located behind the dash board on the passenger side. Look for a wet spot of antifreeze on the passenger side floor area - close to the firewall for an indication of a leaky heater core. If it is leaking, it will likely need to be replaced. This can be a pricey repair.

Good luck!

There is a drain tube that clogs up. It is on the firewall under the hood on the passenger side. You have to access it from under the car. Use a stiff wire and clean it out. Sometimes you can clean it with a water hose and sprayer. Just don't put a lot of water in it. Spray a little, let it drain, Do this till you don't see any mold coming out. If it clears out and you still have water issues. Replace the heater core.

Your heater core has developed a leak - the wetness on the passenger side carpet is engine coolant
from a heater core leak, or a leak in one of the two hoses connected to the back of the heater core.
Your strategy: disassemble dash down to heater core, determine whether you'll need a new heater
core or new hose (or new hose clamp), then replace the offending part.

If it is in the front of the car it could be the radiator, a radiator hose or the water pump. If you can see that it is not the radiator or a hose, look under the snout of the water pump. There is a weep hole there that will leak anti-freeze when the seal is out of the pump.

If it is leaking at or slightly past the firewall on the passenger's side, then your heater core is leaking and will need to be replaced.

Most likely a leaky gasket. The water pump is a likely candidate, but also could be from a bad radiator hose/thermostat connection. Would suggest washing down the engine with a hose connected to the hot water. While the engine is cold use the hose to wash off the oil & grease deposits and old antifreeze. Allow the engine to dry without running the car. Once dry start the car and be prepared to look for the first sign of a leak. Sounds like a dealer issue since there is very little work clearence between the front of the engine and the car body. Barely enough room to be able to change the serpentine belt.

well if you have water or coolant leaking on to the rug in your car, first you must remember that every car has 2 radiators. One for the Engine which is in the front of your car under the hood and one for your heater, which is usually hidden deep behind the dash inside of your car. So if you are leaking fluids on to the rug in the car; Im 90% sure its going to be something dealing with the heater radiator. What you have to do is find out where your heater radiator is on your car and check all the hoses.
