Is battery connected, your heater core doesn't start the engine, is battery dead, retrace your steps, take your time, think, have patience, smile, now go see if you can work it out.

If you changed your heater core, it has nothing to do with the car starting. Did you disconnect the battery when you did this? . The only other thing I can think of is a safety switch that won't allow the car to run if the water is low. This can happen if the system gets air locked. How did you fill the system back up? Did you hit any wires off while working on car? Did the car run fine before you changed the heater core? Let me know and we can go from there Cheers from NS Canada

    Yes, I did disconnected the battery. This car does not have a safety switch. I didn't hit any wires off. Yes, the car did run before I replaced the heater core. I connected all the cables, I also checked that the cable were connected and everything was inplace. I checked the battery and it's not dead, the care does not start at all, the dashboard light turn on but the car won't start it's dead. Any other suggestions? I wonder if I might off had miss connected cables or missed something.

SOURCE: have a 2001 audi a4. I replaced the heater core and have everything back together again, all systems functioned fine except the wipers failed mid swing and the engine turns over but fails to start. He

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

When you replaced the heater core, did you disturb the vehicle's ECU? This is usually under the dash, close to the heater core on many Korean cars and Japanese cars such as yours. If you have disturbed the ECU, its wiring or managed to get coolant on it when changing the heater matrix, then that could be your issue.
If you got it wet, then take it out and dry it and it's connections thoroughly before reconnecting it. Hope this helps!

Was there a problem BEFORE the maintenance or only after?

Car is running in 'limp mode' so it won't drive correctly.

Did you have to pull the dash to get to heater core? IF so, something's still loose back there.

My 1999 jeep wrangler is over heating, smoking and losing coolant , I replace the heater core, replace radiator, replace thermostat and thermostat housing still over heating

It appears that you have a blown headgasket, a failing water pump, or a cracked block.

There is also the possibility of a freeze plug failing & leaking there.

You can bypass the heater core until you are sure your engine problems are corrected so as not to damage it from excessive pressure.

You'll need to reassemble everything and pressure test the system instead of starting the engine, to see where the leaks are.

Good luck !

Electrical - won't start. Hooked up fan to heater, smoke came out from under the hood, car won't start. Lights work, any key related electrical functions won't work

Your fan or heater likely shorted out and burned up, causing your one of the main fuses to blow due to the spike in current. You will need to determine what burnt up and replace it before replacing the fuse, or you may create a fire hazard or cause further equipment damage. Also double check any changes to wiring to make sure that everything is hooked up properly.

Can i by pass the heater core

i`m guessing that you are talking about the heater core blew and you have coolant on the inside of your car.you can bypass the heater core by disconnecting the hoses that connect to the heater core and connecting a hose connector between the two hoses and your done.however if you need heat you won`t have it until the heater core is replaced.

When my trailblazer over heats. there is fluid that leaks out of a drain hose on the fire wall. why is it?

Sounds like you may have water leaking out of your heater core.

This will cause an overheat condition, which you get because your engine cooling system can't pressure up as well.

You may also notice a kind of "sweet" smell to the air that comes from the air vents that blow when A/C or heater is on.

As water leaks into the A/C & Heater core compartment area...it trickles to the overflow drainhose on the firewall. This is usually intended for the condensation of the A/C core but a leaking heater core will drain that way too.

From what I hear, I'd see about disconnecting the heater core hoses going into the firewall and maybe use a splice to connect them to each other OR get a two 5/8 bolts and a couple clamps and plug the hoses.

This allows you to drive car without overheating and buys some time to get you another heater core (basically a "mini-radiator") Its summer, so you don't need the heater right now but keep in mind...you won't have a heater until the core gets replaced.

Hope this helps...
