1989Volvo 240DL Heater hose leaking

The car started over heating but i had to get where i was going. Found the leak in the heater hose? i think anyways. its coming out of the firewall down into the engine. So the plan.. Take hose off see if there is enough room to cut it off and reattach. If not replace the whole thing which honestly looks like a pain. Any suggestions welcome.

SOURCE: Replace Heater Core for Volvo S70 (1999)

It is your heater core. I fixed mine for $144. Ordered the new part on Ebay and followed these instructions It was very simple, I'm a middle age grandmother! The hardest part was cleaning up all the antifreeze. You will need a shopvac, a small one is $20 at WalMart.

SOURCE: Car Heater smells strange

from he Popular Mechanics site if the smell in your car is like maple syrup:

WHEN: After the engine has warmed or possibly even after it's shut off for a few minutes.
THE CULPRIT: Coolant containing sweet-smelling (but toxic) ethylene glycol is leaking from somewhere. It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car. A strong odor inside the passenger compartment probably means a bad heater core.

SOURCE: volvo 240DL sputters while driving

Not enough information here, but I would always replace the crank shaft position sensor first. Its at the rear of the engine, it senses grooves in the flywheel. Next I would check the fuel pump relay. Finally the Airflow meter.

Yes, probably water pump, but easy to do yourself. Change thermostat now as well.

1994 Caprice LS. Little to NO heat.

It will be the heater core. If you can smell it inside the car and it's steaming up the windows the core will need to be replaced. Remove the heater core housing and check to make sure its leaking from the core itself. You might get lucky and have a leak from the hoses running to core instead. Hope that helped.

Leaking antifreeze between firewall and motor on passenger side. just started when i tried to use the heater. could it be the heater core and where is it located

Could be the heater core, or where your heater hoses connect at the firewall. Heater core leak would more than likely put steam in the vents of you car when heater is on and hot and fan on. If the leak is just in the engine compartment, it`s a hose or a loose connection.

My 99 Tacoma extended cab sr5 4x4 has a water leak tha i cannot seem to find. My heat blows fine and I do not think it's my heater core. Anyone else have this problem? Both my driver and passenger front...

Hi, look at this way ,,,, it's wet on both sides on the inside of cabin. Gravity being what it is , check the heater cowling below the heater matrix for (water) dampness. On a bad day there are only two hoses coming thru the engine bulkhead ,,, to the heater matrix , so do the maths yourself . A pressure tester will expose any weak / vunerable hose connection. Good Luck

I put coolant in radiator and I get a/c but my heat doesn't work. I think my heater hose was bypassed by the previous owner. How do I fix the problem?

You should be able to look down in between the motor and the firewall and see if the heater hoses are attached to the heater core. Most of the time when they are bypassed it is because the heater core has started to leak. Instead of replacing the heater core (not a fun or easy job) they just bypass it so they won't leak coolant. So, if it is bypassed your probably looking at replacing the heater core in order to get heat.

Coolant leak cant find it . it only leaks when heats up and it has a heavy drip coming out where the transmission meets the oil pan undernearth

That would be your heater box overflow making that drip on the transmission, which indicates that you have a leak in your heater core. Try disconnecting the hoses to your firewall which connect to your heater core and either blocking them or joining them together to see if the leak stops. If it does, you can leave them that way until you can get to your heater core and replace it.

Water is getting inside of car on passenger side. and i think it effected the radio and heating/cooling system.

The coolant hose going into the heater core gets leak at the clamp end. Need to replace this piece of hose. This sounds simple, but it is not uncomplicated. There are 2 hoses coming in and going out from the heater. You can make a loop to bypass the coolant going to the heater core to eliminate the leak. However, do this way you won't have the heater at all.
