Nissan - Frontier :: 2004 - AC Went Out / Leak In High Pressure Line
Apr 27, 2013
My AC went last fall. I saw signs of a leak in the high pressure line. Took it to the Nissan dealer last week and they diagnosed the same problem. They changed the HP line. Told me it was good, but when they pulled it up, no AC. They took it back in and said the low pressure line was leaking as well so they changed it. Still didn't work, although it was a little cooler but the compressor seemed pretty loud. Told me they thought it might be the thermistor. I bought the sensor and replaced it myself. AC seemed to work, but sure enough, it only blows slightly cool air and the compressor is still making a bit of noise.

After having my oil changed at a local place, the oil pressure gauge showed "high." hoping it would go away, i drove for a week. it didn't... took it back to the shop and they said it was a little full which would cause it to show high pressure. That was earlier today. The gauge however has not changed. Still shows high oil pressure. I need to drive 400 miles tomorrow and am not sure if it is safe? Perhaps just a bad sensor??? I need to know if i can hit the road or not.

I have an 03 Accent. The all metal high pressure power steering line had a leak. So I bought a new one for around 70 dollars from Hyundai. This part has a curved shape and fits around the radiator. The old one was difficult to get off, but the new one is proving impossible to get on. I cant get it into place.

I think I've tracked my power steering leak to some type of sensor on the pressure line, close to where it connects to the steering box:
I assume this is a pressure sensor? I got no CEL or anything like that when the fluid had leaked down to the level that the pump started whining pretty badly though. As far as I can tell by looking at pictures, the parts store replacement pressure lines do not have this sensor, or any provision to connect a sensor to it: Advance Auto Parts: Power Steering Pressure Hose by Powercraft - Part 71878
I may just put a replacement line on there and leave the sensor plug hanging and see what happens...

I have a 2001 Nissan Frontier Crew Cab XE with a V6 (without the supercharger). I bought it on Halloween night with only 42,000 miles. It now has 112,000 miles on it. I moved from Georgia to Kentucky and heard that I needed to have the cooling system flushed/filled to prevent it from freezing in the winter time. I then noticed that it would periodically "overheat." The temperature gauge would climb up to the line just below the "H" and then I would turn on the heater.
I read online about a "bleeder valve" on top of the intake manifold. I loosened it, squeezed the radiator hoses to get all of the air out and then tightened the bleeder valve. I then let it run until the thermostat opened, revved it up to 3,000 to let all of the coolant flow. Now, at various time with no specific reason, it will run fine and then just "decide" to overheat.
I can drive it on the interstate for fifteen minutes, park it in front of my house and then have to "tack it up to 3,000" just to get it cool. I've changed the thermostat and had the water pump tested. Neither of them are faulty. My mechanic vacuumed out all of the air from the system with a special tool the dealer recommends using and it still does the same thing. What's going on with this vehicle?

I've been watching fluid build up on what I think is the hi-pressure line on the hydroboost. It appears to be originating at the coupling in the line because it is dry back at the unit.
Is there an o-ring or nylon washer in this fitting?
Can it be tightened?
Does the o-ring or washer need to be replaced?
Is it a sign of something else, like a build up of pressure in the line that is too high?
I currently have zero problems or noise coming from the steering or brake system.

I have a 2004 Nissan Frontier with V6 non-supercharged engine, 4x4, with manual transmission, 150k miles. For approximately the last 30k miles, I have had a persistent shuddering in the cab when I apply the brakes slowing from about 15 to 0 MPH. It is accompanied by a low humming noise that decreases in pitch as the truck slows down. It only happens when the brakes are warm; about 70+ degrees outside or after I've been slowing down a lot. It does not seem to correspond to engine temperature, only my perceived temperature of the brakes. There is no pedal feedback, and it does not shudder when I stop using only the parking brake. It does not seem to affect stopping distance.
I first tried to fix it by doing a very thorough front/rear brake job - new pads/shoes, new rotors/drums, and repacked front wheel bearings. That had no effect on the problem. I tried rotating the tires and that had no effect. I then did a complete front end job and replaced all the bushings and balljoints via brand new pre-assembled control arm assemblies. I also replaced the tie rod assemblies, sway bar bushings/end links, and had an alignment done. That had no effect.
Based on the repairs I've done, I would assume that it is having to do with the front brakes, but is not warped rotors or anything in the front suspension.

I have a 2004 Nissan Frontier pickup that pulls to the left. I've had the alignment done - no change. I had the tires moved from the left to the right side - still no change. Firestone is recommending I all the front ball joins at a cost of $1200. Is that really the problem?

I have a 2004 Nissan Frontier pickup that I bought used in 2012. Shortly after I purchased it the the check engine light came on, would go off and back on. Last year (before inspection) I hooked it to the diagnostic auto scanner and it read the error as four oxygen sensors. The truck was running fine but in order to get it inspected I ended up changing all four sensors. The light came back on within the week (as soon as it rained) then would go off a few days later. Rain--on, then off. I managed to get it in for inspection on one of the days the light was off. So, now it is again inspection time. Light is on, still error on the scanner as oxygen sensors. Light has not gone off in a long time.
Also noting here that I have checked this error on several different scanners. The truck is running fine. Before I take it to the dealership is there anything else this could be?

'04 frontier 6cyl, 90k miles. My AC recently started cooling poorly, although still slightly cold, especially at higher rpms. At the same time, I noticed a buzzing noise that changes pitch with rpms and only occurs with ac on. I can hear it loudest from the glove box area, and can't really hear it under the hood. The compressor clutch works fine. With the car off, I can spin the compressor and it feels fine, no noise. With ac on, the low pressure tube gets cold. I hope it's not a bad compressor.

How do you get the line back on to the rack? There is absolutely no room and I have experimented with a variety of tools with no luck. What's the trick?

The power steering fluid in my 2004 Nissan Frontier crew cab leaks as the weather turns cold, the colder it gets the worse it leaks.

So, I just found out that the noise my car has been making is related to the power steering. The mechanic said I need to replace the pump, two belts and the high pressure line. The car is a 1993 Honda Accord LX. I can't afford to have the mechanic fix it, so I'm going to have to do it myself. My questions are:1) how long should it take me? I'm not experienced at all. I was thinking of just doing the high pressure line as a 'warm up' to start. Is half a day wishful thinking? Any tips?
2) The mechanic said the hose is leaking all over the belts. He said it was "squirting and pouring out". I tried to duplicate the squirting by turning the wheel all the way and revving the engine. What I saw was a very small leak at the joint. So small it wasn't falling, but I'm sure it would if I waited long enough. The belts appeared dry to me, but I'm not really sure what they are supposed to look like. The mechanic said that they are getting soaked in fluid and that I might throw a belt. Anyway, so my question is how can I tell if the belts are "soaked in" steering fluid.
3) I've been told that if the belts are getting steering fluid on them they might be responsible for the loud squealing noise when turning. If I clean the belts with degreaser, and the noise stops, does this mean that replacing the leaking hose would be sufficient?
I'm making a long road trip in about a week (ca to wa). I'd prefer to deal with the replacement when I get to wa, but I also don't want to make things worse.

I have a 2003 Ford Excursion with the high pressure line leaking. My guess is that the original line had a rubber hose and was replaced with a 3/8" ID high pressure hose. My problem is that I can not get the 3/8" ID replacement hose over the second larger bulge on the line going to the radiator cooler. What am I doing wrong?

I own a 03' 2.7 Santa Fe (2wd) and when I got home last night i noticed that she was smoking like crazy (not overheating). Opened the hood looked under the car and noticed some fluid spraying on the the exhaust and leaking down from there which was causing the smoke. I put her on jack stands and noticed what looks like to be some hard (i think pressurized) lines that are attached to a connector of some sort in front of the steering rack. What lines are these? Power steering? oil cooler? Transmission related? The fluid that is leaking looks like transmission fluid cause its reddish brown. Ive worked on a few other cars before but not too familiar with Hyundai. When i get home later I will take a pic of this area and post a picture. And it looks like its spraying from the connecting lines (maybe a crush washer gone bad? ) not sure. I can't seem to find any image of this area online either.

I've found everything there is to know about disconnecting the high pressure oil STC line from the oil rail on the early 6.0's, but I can't find anything about reconnecting them. Do you simply press it back on? Should there be an audible "click"?

I just replaced my 3rd HP power steering line last night( 3rd in 300K, always blows the same point....fitting comes apart where it attaches to the pump.
I'll start, mine have gone about 100K plus or minus 10K, almost thinking about making it a 100K maintenance item.

I have a gas leak at the connection of the High Pressure Fuel Pump and high pressure fuel pipe. Gas drips and sprays out from the nut area (see pic). The car take a several seconds to turn over to start.
What is the most likely cause? The car is out of warranty, so trying to repair myself without having to replace any expensive parts unnecessarily.

Truck has a high oil pressure leak, only leak i have found is in the high pressure rail, I cannot get to it till sat, or sunday. So I have to let the oil cool before I can start. Any way testing to find the right temp for Oil to thicken enough to Build? I've been here for hours and its went from 180's to about 100 now...

I have a High pressure oil leak somewhere, and where it can be. I tore the oil rails out and replaced the nipple cup seals last night. I got it all back together and air tested it and sure enough a leak is present. I have no problem paying for your time (I always provide good beer). I can rebuild gas motors all day long, but these diesels has me thrown for a loop. The frustration I am experiencing is crazy at this point. All the injectors are new, and the dummy plugs and standpipes were replaced as well.

I have a '99 Nissan Frontier 4cyl. p'up and the air conditioner kept going off. The truck has three drivebelts, all inline. The first is Crankshaft to the Power steering pump , the second goes from Crankshaft to the water-pump & the alternator and the third one goes to the air-conditioning compressor; the one that keeps coming off my truck & shutting down the A.C. I replaced it three times and the last time it went off within a couple of miles. I know the crankshaft and the A.C. compressor pulley's are out of line and believe that's my problem. A mechanic friend of mine looked at it and said he thought it was something called a belt-leveler that keeps all the belts from slipping off.
