Hi

I replaced the radiator hose in my son's 89 240sx because it had a small crack in it. The car started and ran fine.........until.....later in the evening when he called me to say it died when he came to a stop and he couldn't get it restarted. It took me about 5 min to get to where he was and it started right up but I had to keep revving when I came to a stop so it wouldn't croak. This morning it's just cutting out 2 seconds after I start it even if I rev it.

When I removed the hose to replace it, coolant came spewing out and landed on the engine so maybe something got wet that needs to be dry? ;) That's the only thing I can think of. I checked all the hoses going to the plastic air tube thing (sorry I don't know the official word for it) and etc and everything seems fine and intact.

Any insight would be appreciated. It ran better than perfect before I replaced the hose.

Edited to add:IF coolant somehow got mixed in with the gas would dry gas or isopropyl help clear that problem up??

ThanksLaura

check your MAF wires..they could came shaken loose or something-(it's the metal thing..right before the air filter thing..on the plasstic hose thing across the top of your radiator)

Success (I think!) - It wasn't the wires but you sent me in the right direction. I found a hose that was loose on that side. I snapped it back in and it "seems" to be ok though I haven't taken it on a long test yet.

Here's the pics of what it was

What is that hose for and what is that thingy it's connected to? :)

Thanks!

Can someone tell me what that black box is in the picture linked in my previous post? I thought I had to just snap the hose back in place but the car started acting up again and I noticed now that the part of that black box (thingy :) ) that the hose is connected to is actually snapped off

ThanksLaura

Thanks. Do I just need to get a new case or is there more to it than that?

Well, the hose that is connected to it (the one I'm holding in the picture) was off and the car wouldn't stay running. It started but then coughed out quickly. I reconnected it and it was fine.

Then it jiggled loose again today about 3 weeks after the above event. That's when I notice that the piece that the hose connects to was actually broken from the box. Anyway, the car wouldn't stay running again. I snapped it back in place and now it perfect, but it's bound to come loose again.

Go to the junk yard and get a new one, or put a new hose nipple on the broken box. It sounds like you figured out your problem! :)

I assume it must be similar to the MAFS, in that it needs to register a reading for the car to run.

Ah well, it was just a thought! So worst case scenario it's pulling dirty air into the exhaust manifold. The s14s (or maybe all KA24DE engine 240s) have no such device as far as I know..... any particular reason?

The nipple that broke off the box is still in the hose. Do you think if I super glue it back to the box it will stay put (for now until I get a new box)

When I do replace the box is there anything in there that should be replaced or cleaned while I'm at it?

I woud suggest going to the plumbing or hardware store. I don't have a technical name for it, but you can usually find a universal nipple that would be inserted from INSIDE the box... through the existing hole. It would be held in place with an epoxy and, basically, sandwich the wall of the box between itself and the hose.

All s14's come non aiv'd. Z32's after a certain year dropped the aiv as well. Reason is because its basically useless, and is also one of the first emissions devices to be removed, in our group.

Going to look at the image then edit.

edit I would just rip the thing out, as I will do on my gf's 92 when I become not so lazy on her car, and plug both the exhaust and intake sides hehe.

Best bet would be to get a JY one. Second best would be to epoxy it back in place.

If you want to just replace the barb go get either a 1/2" or 5/8" (cant rem which it is rtight now) OD barb with 3/8" threadded female mip fitting. Re drill out the box to be able to screw the threaded part in (get a nut, cumpression fitting nuts work good sans compression sleeve, for the other side but its not needed). Think its like a 5/8" hole or something close to that. put epoxy on the threads and thread it in. Then epoxy around the base of it just for fun.

The barb should cost like 2 - 3 bucks, and well I have epoxy and a drill with a proper bit so that wouldnt cost me anything.

But at a JY, like my local one, its probably ony 3 bucks as well hehe.

It would be about $5 total for the nipple and epoxy glue. If you go to a junkyard they will charge a minimum of $10 for that plastic box.... that is if YOU pull it. Then you have to uninstall the part twice and install it once. I'd go for the ghetto fix!:D

BTW tell your son to do his own work hehe.

Make him learn then he can fix your car. At least thats what every one uses me for around here :(

Thanks again for all your help guys. My dad was always under a car when I was a young girl so I have some basic knowledge....enough to be bold enough to TRY to do something myself.

My son DEFINATELY needs to learn to do his own work. He's out there with me when I do or check anything and I've been giving him the basics (check fluids, change tire, jump start, etc) but unfortunately I don't think he'll ever be the family car fixer :(

I think it's great that you are out there getting hands on with your son's car.... and showing him the basics. My Dad and grandfather both brought me along every time they worked on their cars. I'm not much of a mechanic, but I gathered a lot of valuable experience this way. Also, the value of spending time with your kids in a constructive environment is unfortunately underrated in today's world.

Well, there's a funny (but scary) reason for my teaching him the little things that I took for granted that he'd know.....

One day I told him that one of his tail lights was out and we needed to replace it. He kept looking at me with this perplexed look and when we went outside he kept asking me (in that I'm a teenager and I know everything voice like I was crazy) "What are you TALKING about? It's right there!". I opened the trunk and showed him the light assembly and he said "Oh, I didnt know those were lights. I thought they were reflectors that glow when the car behind you has their lights on, like on bikes"

That's when I figured I had better shove his head under the hood.

Less weight and less areas for exhaust leaks to develope.

Basically you plug the exhaust tube by a bolt or cut and weld, and then plug the airbox hole (or get a new filter like a POP charger).

Then remove everything between the two.
