Question What am I looking at here?

I noticed something funny going on under the hood today. I noticed this green substance leaking from these hoses pictured here. Im not sure what it is. It started to kind of pool a little in the space under the battery, and even drip down onto the driveway underneath making a spot a little bigger than a quarter. Should I be worried? It did just rain today. Maybe it has something to do with that?

↑ Bingo, Leaking antifreeze is bad hopefully its just the loose hose clamp. Try tightening it up and see if it still leaks

Umm it depends on if you have A/C or not...if you do, its alot harder. Normally when they have a problem it leaks in the passenger floor.

If you have anti-freeze leaking on the passenger side floor it's definately your heater core. In this case I would try to tighten or replace the heater hoses first and use new clamps.

Go ahead and change the hoses and clamps first. You will have to (want to) anyway if you end up changing the heater core so no lost $$$. Especially if more than 5-8 years old. (What vintage did you say?)

Winter in coming...

Those look like the orginal clamps...maybe you should take a close look at your cooling system before you make any decisions.

This is what I would do...but I've been know to do things that others will not

Wait until your engine is cool and pop the radiator cap off. Take a peek inside and say "hello" ... if it echos back then sell it ... just kidding!

Really...take a look at the coolant level and the condition of the coolant. I would recommend flushing your system and evaluating what needs to be changed. PREVENTITIVE maintainence...

Drain the radiator...remove the upper hose and take a peek inside. Is there rust? How about the lower hose...any swelling? Are the clamps digging into the hoses?

If your hoses are as old as those clamps are then you need to replace them before winter comes and you're left with no heat or even worse, left on the side of the road.

Prestone makes a cooling system cleaner that works great. Remove the thermostat, replace the housing, fill with water and Prestone's flush. DRIVE for about a week with the water/flush. Pay attention to any leaks. Leave your HEAT on to allow the flush to get into the heater core. If it's going to leak or fail it will let you know and better it fails with water in it.

After your week of driving drain all the water and muck from your cooling system. You may need to put the hose in the fill neck of the radiator to force out any debris in the radiator. Remove the upper and lower hose at the radiator, put the garden hose in the upper hose and flush debris from the engine.

NOW...what are you replacing? I say thermostat, uppper, lower and heater hoses with clamps.

That was a mouth full...your alternative is put a new clamp on your heater hose and ignore cooling system until it fails.

Hope this helped!

Hose removal

When you remove the heater hose ... either use a HOOK TOOL to remove the hose from the inlet/outlet OR...

CUT the hose along the length with a razor blade and then use a flathead screw driver or HOOK to seperate the hose from the core.

You can easily damage the heater core by man handling the hoses during removal.

This has helped a lot everyone, thanks! My YJ is a 95 with NO AC and currently no antifreeze on the passenger side and thankfully there never has been.

I just got a 95 YJ with the 2.5, and I really want to go through it, just to make sure the fluids are clean and stuff. Is there a special way to fill the coolant, I had a Honda that you needed a special tool that only the dealership had, in order to prevent air bubbles. Thanks for the help!

Just fill at the radiator and half fill the over flow. Monitor the overflow and add the appropriate amount after time. Check the radiator cap and it should be plumb full. The 2.5 should automatically purge any air bubbles through the overflow.

Hey Tkorona, if you drive your jeep in the meantime, keep a close eye on your engine temperature. You do run the risk of overheating when you have a coolant leak. Overheating can cause very serious problems with the engine so it's worth the effort to watch it closely until you get this fixed. Buy a bottle of coolant and keep it in the back of your jeep. Check your coolant level daily by removing the radiator cap and top it off as needed. The radiator should be filled to the top with coolant. This should keep you safe from any further damage to your jeep until you get the problem fixed. If it's just a loose hose connection or old hoses which need replacing, your talking about a very easy and very inexpensive repair. This really isn't anything to be too worried about. If it's the heater core that needs to be replaced, here are the steps you'll need to be prepared to take to remove it:

1. Remove the passanger seat.
2. Remove the battery and battery tray.
3. Drain coolant. There is a drain valve at the bottom of the radiator which you should be able to open with your fingers. If not, use a pair of pliers but be gentle with the plastic.
4. There are four bolts coming through the firewall which attach the entire heater core and blower motor housing. All four are connected to the firewall with 7/16 nuts. One of them is in plain sight and easy to reach while leaning over the passenger side fender, two of them are below the battery tray and one is behind the valve cover. Remove the nuts.
5. Detatch the two hoses (the ones you took a picture of) from the nozzles coming through the firewall.
6. The blower motor protrudes throught the firewall directly below the battery tray. There is one wire attached to the back of it. Pull that wire off of the motor. Just below the blower motor, there should be a rubber hose about 5" long with a 90 degree bend in it. pull this off. It's a drain hose for coolant should your heater core sprout a leak.
7. Remove your stereo from the dash board. This will give you very easy access to disconnect the defroster duct from the heater core/blower motor housing.
8. In order to gain a little more wiggle room for the housing assembly to come loose, disconnect the lower part of your dash (the part with the air vents and evaporator core) and lower it to the floor. There are four screws along the top edge holding it onto the dash.
9. There are two hoses attached to the evaporator core. do not disconnet these hoses. Remove the screws which secured the gromet to the firewall which these hoses pass through. This will allow a little bit more wiggle room.
10. Grab hold of the heater core assembly and work it loose from the firewall. Once you have it down to the floor, detach the three cables from the assembly which control the flaps inside the ducting. After removing these cables, pull the assembly out.

Turn on the heat as high as it will go... if it wreaks of antifreeze then you have a bad heater core. The coolant will not necessarily leak into the cab unless the core casing has been breached it is possible for the core to leak into its casing and your blower will blow coolant steam out thru your vents eventually the coolant will eat thru the casing and leak into the cab as well but you should know that your heater core is bad long before this happens.

I had this issue with my '87 Ranger, repairing was too much so we just capped off the hoses going to the heater core and rerouted the heater feed into the return line. I had no heat but at least I wasn't choking to death on coolant fumes any more.
