If you are scared your heater core will die and leave you stranded, please read -->
This past weekend, I was out of town when my heater core died. When a heater core dies, it will crack and leak hot coolant in the interior of your car. It will run through the vent tubes and eventually drip on your right foot and on top of your very sensitive ECU (something you NEED to drive). When this happened to me, I needed a ghetto repair so that I could get back into town. I found a cheap fix that everybody can appreciate. What you will need to do is, first, bypass your heater core so that no more coolant flows through it and leak.
There are two heater hoses going in and out of your heater core on your firewall. Remove the smaller top hose that goes into the top heater core fitting. Next, remove the heater core side of the longer/bottom hose and simply connect it to the solenoid valve thingy on the firewall. That's it!!! It was that easy! I didn't have to buy any parts and the hose easily bypassed the heater core without kinking at all!
Take that smaller, top hose that you just removed from the heater core. Connect it back up to the top heater core fitting and blow on it as hard as you can until all of the coolant blows out on the ground from the bottom heater core fitting.
After doing this 15 minutes job, I didn't have a single drop of coolant drip onto my ECU. Just in case, I lined it with paper towels and kept an eye on it my entire drive home. Not a single drop.
I got this idea from Matt93SE who wasn't completely sure it would work without kinking the hose. But, it worked great on my car. Of course, your hoses need to be in decent condition and not brittle.
Here is a drawing I made to help you understand this. I also posted this on my website with more information. Feel free to check it out.

I hope this knowledge helps someone in the future when their heater core suddenly goes out. If it hasn't, then it WILL. So be prepared with a #2 phillips and a flathead screwdriver. I ALWAYS carry a nice tool kit in my Maxima. And don't let your ECU get wet or you will really be screwed.

I had to do this once on my 1978 Datsun 810 Wagon (Straight 6, fuel injection, rear wheel drive)... my FIRST Maxima! The heater core was OK but I had burst a coolant line and had to invoke the Ghetto Clause of the Rules of Repair and bypass the heater core.
It worked so well I drove all summer and into the Fall with it like that, but quickly remembered my "ingenuity" one very cold Maine fall night with the family in the car and NO HEAT! I can deal with a little cold, but the incessant whining emanating from the (now ex-) wife was intolerable.
Later had to upgrade and trade Wife 1.0 for Girlfriend 2.3. That solved the problem.

i did this to my car back in '00 but my heater core didn't go out but in fact everytime i would turn on the A/C it would only blow out hot air so i just ended up bypassing my heater hoses and now i get cold A/C. weird but true.

It's hard to understand what you are trying to say since your English is so bad. But it seems that your ECU shorted out and you need a new one. If you are able to give more details about your situation, then I might be able to help you further.

the ECU got wet, and the car starts to fail and to shake much in low revs, if I accelerate is made up, but at the time of letting accelerate the problem returns, check engine is on, and if I accelerate with the transmission in Parking (P) the car shut off... Hope you can help, this time i use the babelfish translator

I take it to the scanner, and they cant pull put any codes...just a bip,lol... so They say that my ECU was not working, and cant explain why my car is running...the guy told me, its a miracle ...

Try to purchase a used ECU and that might fix the problem. They are not expensive here in the USA. Hopefully they are not expensive in Japan.

Well. i already install the new ECU, the car runs better but not enough, and the check engine light its still on, i pull the codes using the info on this page...results
35 Exhaust Gas temperature sensor
51 Fuel injector circuit open
What can i do to repair them?? Mainly the 51, cuz i think thats the major problem..
And both errors say (california models only) so i guess i have a california model? how could i know that??
Pleas help guys...

Yes, the #51 is the major problem here. I would just test your injectors. It's very likely one of them has failed. You can test the resistance of each injector by touching the two terminals on the injector while it's unplugged. If it's between 10-14 ohms, then it should be ok. But if it's outside that range, replace the injector. Also, the injector might be ok and you could just have a bad connection somewhere or corroded terminals on the harness. Also, it could be a leaking injector due to one of the orings going bad.
If you want to learn how to fix everything on your car, then I would get a Factory Service Manual for your Maxima. If you don't want to fix your car yourself, then take it to a shop and let them deal with it. Or you can start here:
http://www1.autozone.com/servlet/UiB...3d801f5140.jsp
If this link doesn't work, then make sure you search for 1994 Maxima and you will find some information for your car.
*Edit: Oh yeah, also, it's possible that you bought the wrong ECU for your car. It's possible that you don't have a California Maxima, but bought a California car. If that is the case, then you WILL get the Exhaust Temp Sensor code!! I have that code now b/c I am running a California ECU on my Fed spec Maxima. That is just temporary anyway. I wouldn't worry about the Exhaust code you got. But I WOULD worry about the injector code.

Thanks...Off course i wanna learn how to repair my max... btw, i pull the codes using that page, then i guess i can fin there where the injectors are or how to check them...stuff like that, im still learning, so i dont know where they are located...
Anyways thanks a lot... ill try to post more if my english get better ... lol

Well right now im translating the FSM... Another question, the new ECU says GG instead of GB...could this make some trouble?? Like the lack of power until certain rpm... i have custom Exhaust ( no cats) and i hear something like if wasnt enough gas to fill up the pipe, i mean mm like cough cough lol... and before that my car run out of gas because...im starting to doubt about the new ecu, the car feels diferent but not good...
Sorry about all the question and my bad bad bad english

It's the big bar that goes all the way across the dash. All the dash parts and console parts bolt to it. So there's really no way to eliminate it. Plus it serves as a chassis brace.

MrGone, why did you edit my post earlier? I simply posted a website that has FSM downloads. It's not my problem if it's copyrighted. I just linked a good website. www. is a great website!
