Ever Victorious Posted December 8, 2005 Share Posted December 8, 2005 OK, so the coolant return line from the heater core to the water pipe (?) on my XT blew this morning, good 1" crack, lost all coolant. Doesn't look like I overheated the car, though, so I may be lucky. there are two hoses that come forward from the firewall that contain coolant, one is the cracked one, the other I assume is another coolant line. Anyone have any advice or know of any pitfalls in replacing these? Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted December 8, 2005 Share Posted December 8, 2005 I don't have any real advise for ya.Should be pretty strait forward.I would replace both lines if you can just to prevent it from happening again. Link to comment Share on other sites More sharing options...

I plan to. If I can find the part number of what I need at Schmucks. They have so freaking many hoses listed, I have no idea what I'm looking for..

Subarian Posted December 8, 2005 Share Posted December 8, 2005 Not sure about the routing on the XT, but on the GL you have to make a couple of 90 degree bends to go around the bellhousing/clutch. I sweated 5/8 copper pipe for the bends and used 5/8 heater hose to replace mine. Link to comment Share on other sites More sharing options...
rallyruss Posted December 8, 2005 Share Posted December 8, 2005 go to a real parts store or the dealer if you want the right molded hose. when removing the old ones DONT PULL on the fittings sticking out of the fire wall. that is your heater core and it is easily damaged. make a cut in the old hose(your gona chang it anyway) and peel it off the fitting. I have had good luch using regular 5/8 heater hose or silicone hose. I just zip tie it so the clutch linkage does not hit it. but thats on my wagon and RX. the XT may be different.

That's good advice there... thanks! I'm gonna go replace the hose now... Link to comment Share on other sites More sharing options...
idosubaru Posted December 11, 2005 Share Posted December 11, 2005 on the XT6 one heater hose goes to a metal line that runs under the intake and to the water pump. i removed the metal line and hose at the water pump and ran one piece hose from the pump to the heater core, reducing the number of hose clamps by two for whatever that is worth. general hose worked fine for me in the past on XT6's. take the old hose into the parts store and they'll match it up. be sure to check it, easy for them to assume the wrong ID.

Ever Victorious Posted December 11, 2005 Author Share Posted December 11, 2005 OK, I replaced the line $%*@#$%@#%.... anyway. New problem: the car won't start. All I've done is replaced one of the heater coolant lines (the one that was actually split, I'll worry about the other one next weekend). I checked the ignition coil wire, it's secure both on the coil and on the dizzy cap. The car turns over, but doesn't sound like it's trying (or able) to fire. Occasionally, if I've been turning it over for several seconds, I'll get a "lug" out of the engine (like one single fire) after I release the key. Ideas? Starting problems are something I have almost no familiarity with... so treat me like I'm the idiot I am on this one... Link to comment Share on other sites More sharing options...
Cougar Posted December 11, 2005 Share Posted December 11, 2005 The reason the engine tries to fire when you turn it off is because the coil electrical field collapses when power is cut off. This means that the coil is not seeing the firing signal pulse which is a ground on the negative side of the coil. My guess is that you may have caused a connection problem to the distributor while working on the hoses. Look over the wiring to the disty for a problem.

Subarian Posted December 11, 2005 Share Posted December 11, 2005 OR.... when your heater hose split, you may have gotten moisture in the distributor. Link to comment Share on other sites More sharing options...

My guess is that you may have caused a connection problem to the distributor while working on the hoses. Look over the wiring to the disty for a problem. All 5 of the wires going into the top of the distributor are properly seated, as is the disty wire to the ig coil. Is there a specific wire I need to look at? OR.... when your heater hose split, you may have gotten moisture in the distributor. This seems more likely, as the output line split on the outboard (driver's) side of the line, spraying everything between the hose and the fender, about 4 inches to the front and rear of the split in the line. How is this fixed? parts? opening it up and pointing a hair dryer at it? Link to comment Share on other sites More sharing options...
Snowman Posted December 12, 2005 Share Posted December 12, 2005 Yeah, just take off the disty cap and see if it's wet or dry in there. Link to comment Share on other sites More sharing options...
Ever Victorious Posted December 12, 2005 Author Share Posted December 12, 2005 Yeah, just take off the disty cap and see if it's wet or dry in there. Dry. Poked around at the connections on the underside of the coil and there was this round connector with four pins inside it that was SLIGHTLY disconnected. After reconnecting, it fired right up. I need to look at it again later... not leaking coolant any more, but it gets to about 75% of the way to hot before it stops... whereas before it would get 60-65% there and then stop. Edit: (rereads specs on the XT) Yeah. Probably don't have enough coolant in it... I put in about 2 quarts, mixed... says 6.1 quarts capacity. And I'm fairly certain I had basically no coolant left...

Cougar Posted December 12, 2005 Share Posted December 12, 2005 Check to see if fuse #5 is ok. If the horn works you should be ok there. Link to comment Share on other sites More sharing options...
Ever Victorious Posted December 12, 2005 Author Share Posted December 12, 2005 Check to see if fuse #5 is ok. If the horn works you should be ok there. Overheat was just low coolant. Added another 1.5 quarts mixed, and it went right back to where it should be, at about 65% at its very hottest. Link to comment Share on other sites More sharing options...
Cougar Posted December 12, 2005 Share Posted December 12, 2005 I'm not sure what you meant in response to my last post. Fuse #5 is important for the ignition system so you should check it. Since the horn is on this circuit also it would mean the fuse is ok if it works. Link to comment Share on other sites More sharing options...

Poked around at the connections on the underside of the coil and there was this round connector with four pins inside it that was SLIGHTLY disconnected. After reconnecting, it fired right up. I had posted this before you posted your response. So nothing, I guess. Link to comment Share on other sites More sharing options...
Cougar Posted December 12, 2005 Share Posted December 12, 2005 Opps. I missed your statement about the engine firing right up after setting the connector. Glad you got it going. Link to comment Share on other sites More sharing options...
