I have a 2003 Ex with the 7.3. There is a leak in the rear coolant line just in front of the rear right tire. Is there any way to bypass the rear heater under the hood?
View 1 RepliesOn my 2003 Excursion 7.3L, I notticed I'm leaking what I think is coolant from the passenger side rear hard line by the front spring hanger. I haven't pealed the plastic loom away yet, but I did see the loom is chaffed near the spring hanger. What lines are the ones that carry coolant, and can I just cut the hard lines and replace with a section of rubber hose?
View 3 RepliesI just purchased an 97 E350 (15 Passenger) and I notice that the two rear heater lines (along the driver side) are rotted and is showing sign of minor leakage. Can I simply replace them with rubber heater hoses or do I need to get the factory heater lines?
View 6 RepliesGot F-150 4.6 cooling system leak on the heater line (farthest back line) coming out of the block. Fitting looks to be steel. How does it attach/ do I need to remove the Intake to replace?
View 5 RepliesSo I finally got my truck running on sunday and I come home after work yesterday and my driveway is covered in coolant. the line that goes to the rear had split in the middle and also in the rear?!? Where to get a replacement. I was thinking about just cutting out the messed up section and hose clamping some heater hose in its place?
View 12 RepliesRear steel brake line ruptured the other day (was pretty rusty). Despite being an idiot in regards to automotive repair (among many other things), I decided to give it a shot. I was able to get the damaged section off, went to Autozone with the broken piece, they matched it up, were nice enough to cut it and put on one larger fitting (because the two were different sizes) and flare it for me.
I was able to get the one side (at the T fitting) on OK. That was the "new" side, the one they flared at Autozone. Looks good. No leaks.
The stock side, at the passenger side caliper, leaks like crazy. Not out the threads, but out the hole through which the line passes. Know what I mean?
I'm having a hard time figuring out what's happening, because I'm not sure how this thing works. Does the line fit flush to something inside the connection at the caliper? Is it a bad flare?
It did not go in easy, but the new one was just as much trouble as the fitting that came out (stock?), so it must be right.
I have a leak where my heater core tube goes into the intake at the rear pass side of engine. I have read that this part is pressed in. I dont want to remove the intake since i just paid $400 to have a new gasket kit put on. My question is can I bypass this tube with a hose from the water pump like in this video?
FORD 4.6 , 5.4 , 6.8, HEATER HOSE UNDER INTAKE REPLACEMENT THE EASY WAY !!! - YouTube....
If I can do a rubber hose like in the video I was to make sure that the tube just goes through the intake and that it does not supple coolant into the intake??
It seems that the install of my Doug Thorley headers didn't go as well as I thought. Turns out the passenger side header melted the bracket holding the heater lines and then punctured one of the lines when it rubbed against the header. Right now I'm not sure what to do. I noticed the melted bracket and pulled the fender well, but that's when I noticed the leak. I guess some of the melted plastic was keeping it from leaking everywhere until I removed it. I live in AZ so the rear heater isn't really necessary so if a stop gap measure is to bypass it then I'm game but I can't find any info on how to do it. If the only real solution is to get the entire line replaced then I'm a bit hosed I guess. 2001 V-10 4x4 BTW.
View 6 RepliesTrying to get the a/c working on the EX. Tried to pull a vacuum and heard a leak coming from near the firewall. After a closer look I could see the larger line was rubbing against the rear head stud. That line is a hard to remove and replace. So if you have a studded 6.0, take time to look at your lines to make sure they have proper clearance.
View 1 RepliesThe oil cooler mounted above the oil filter on my 2002 Explorer 4.0L V6 has a major coolant leak on one of the external line/hose bib elbow. I've googled Explorer oil coolers and I've searched this forum with no luck. Can you bypass it without any problems mechanically or electronically (throwing error codes)? I have already purchased a new cooler and the lower oil cooler line. I'm just wondering if I should return the parts and bypass it. If I go through the replacement, I noticed the cooler is mounted by a pass through threaded tube with a hex head molded into it for fastening/loosening purposes. What size hex head socket it is?
View 12 RepliesI have a 1990 F-150 w/351 that I knew had a coolant leak at the back of the engine when I bought. It's a tinker around truck, something for me to play with.
I've traced the leak back to a metal tube/pipe that sticks out of the engine compartment just below the AC housing. I cannot find anything in the Haynes manual or a diagram on the intertron that shows what this is and if it should have a hose on it or...?
My coolant says it is low. This happened last winter and I just had it topped off. This winter the car has been stored and I've been starting it every week and this time it sat for four weeks and started just fine but that's when the coolant light came on. The coolant is about an inch below the minimum line and there isn't any coolant on the ground.
View 7 RepliesI'm feeling a bit embarrassed posting my delima, but I have a minor coolant leak which seams to be coming from where the heater hoses connect to the water pump and as well to the thermostat nuckle thingy. I have replaced all of the hose fittings with SS band clamps.
A couple of weeks ago I replaced the water pump, thermostat, alternator, rad hoses, belts, coolant sensor, PS tension pulley. The water pump is now tight and sealed. Since then the temperature gauge has been continually fluctuating from Normal to near Cold.
I was wondering if I should have placed some type of sealant compound where the heater hoses connect to the water pump and also to the thermostat nuckle thingy.
Initially, I thought it may be residual trapped air in the coolant system. But after a week, it became apparent that the heater hoses were leaking at the engine, and at the water pump, connections.
What puzzles and torments me is why is the temperature gauge fluctuating so widely up and down? This is totally weird.
I am not sure if it is the high pressure or low pressure line. The line had rubbed on the frame and it wore a hole in the line. I want to get this fixed and wondered any remedies or if I need to replace the whole line. Someone said I could take it to a radiator shop and they could repair the line???
View 14 RepliesRoutine maintenance gone wrong.
Installing rear brake line and failed to put on the rear washer and stripped out the bolt hole mostly. Will still unscrew and screw back in but not enough to stop a slow drip. Is there an easy repair or time for a new caliper? Thread tape is not brake fluid resistent.
If no repair, what brand should I go with? Are they all similar or MC better? Can get Fenco for $50 and MC for $100. A1 Cardone and ACD for about $75.
02 F150, 5.4 gas motor, about 338k miles. Bought this truck well used so I would have a truck when I needed one. Someone has removed the heater control valve. I've got a new one, but there is a port on the top for a vacuum line, but where this line plugs into.
View 1 RepliesSince I bought this '05 Ex, I have had a driveline vibration. Not bad mind you... just barely noticeable when I let off the gas going 50+ mph. I had my local Ford dealer change the Ujoints and it worked a little.
I just installed Firestone Air Bags on the rear axle. I put 20 lbs. of pressure in them and it raised the rear exactly 1 inch (I measured before and after). After the air bags were in and pressurized and the rear lifted 1 inch, I took it for a drive. WOW! The driveline vibration is completely gone. Smooth as glass.
Question that I need opinions on from those who have more experience with an Ex than I do: Did my rear springs sag enough to cause a driveline vibration? And did the lifting of 1 inch put it BACK to stock height so that the driveline is now correct?
I did a coolant flush following the instructions posted on this site. In fact I did a little more than just a flush - replaced degas bottle cap, replaced thermostat and installed a coolant filtration system.
There were no leaks before I started and the only reason I did the flush was that there was green antifreeze in it.
I noticed that there was half a gallon of coolant under it in the parking lot this afternoon - the degas bottle still has coolant in it, so I drove it home and inspected the thermostat housing and top radiator hose, as well as all fittings and hoses installed as part of the coolant filter. Everything was dry.
I tracked the leak to the lower radiator hose - the one thing I did not touch as I drained from the petcock. Coolant is running down the lower radiator hose.
Could the new radiator cap have increased the pressure in the system to a point where it identified a weak point that was not leaking before?
My temps are great, ECT is stable about 188F - 190F and EOT is stable around 192F - 194F. I ran it hard and got temps up to around 200F and they both came back down to 192F range very quickly when I backed off. They were actually running about 5F higher before the flush.
I will try running the old cap to see if there is a difference, but if the lower hose is the weak point I'd prefer to replace that and run the new OEM cap.
Okay, the vehicle is a 1988 E250 ClubWagon 7.3 IDI diesel with front and rear AC/heat. I have 3 questions for you:
1. I found that the rear heater core is getting coolant flow constantly which is making my rear AC blow 75* air. These models don't have a blend door in the back, they appear to have a valve that is only allows coolant flow to the rear heater core when the heat is turned on. Problem is that I can't seem to find where this valve is located on the van or what it is called to locate it at a parts store. Where on my van this valve is located?
2. My rear blower only functions on High. I know there is a resistor set up in the rear that controls the blower speed. Before I just replace this, is there a way that I can test it?
3. Is it possible that the Resistor setup for the rear fan speed would also be causing the rear coolant flow valve to not work? I know it's a long shot, but does the valve signal flow through it when the AC is on to tell the coolant valve to shut?
I'm 1/2 way through a flush and water pump replacement. Its going to get cold and I don't want to blow any heater lines. I have the pump off and the block drained (I also managed to get some coolant into the block - but not the rear heat).
I don't see an easy place at the front to disconnect the lines. I'd like to blow them out just to be safe. What is the best place to disco in the front or if I even need to - can I just disco 1 in the rear and then blow in both direction?
I fear that there may be some vent door closed that will prevent flow. I can't start the truck - I can turn the key on.
I have 2005 4x4 6.0 excursion. The rear heater stop working. I just get cold air in the back seats.
