New problem arised WTF??

Alright I over heated after going to get a couple parts for the camaro.
As Im driving back home with my roommate, she over heats.
Put some more coolant and what not in and she is still steaming for some reason?
Then he finds a little something.. I got my passanger side carpet full of coolant. And tear away the little covering over it, and then im leaking coolant from somewhere.

I cant really pin point it from my engine bay, but anyone else have ideas??

In most vehicles the heater uses radiator fluid as the heating medium. Commonly could be a loose connection on the interior side of the firewall or more likely in an older vehicle, a core itself, which has started leaking.

How hard is it to get to the hose and the core??
And which could I live without, without any major issues for 2 weeks (my next paycheck)

Re: New problem arised WTF??

huh... mustang guy... you should be used to the Fix Or Repair Daily syndrome...

at the firewall there are 2 hoses clamped that run through the firewall into the cabin... disconnect both and find a piece of copper pipe to connect the 2 together... then replace your heater core at your leisure... just watch the temps and make sure your fans are coming on... probably the cause of your over heating... BTW it is a $12 relay to fix the fans... it is very common too

Re: New problem arised WTF??

Looks like you got a reliable answer here. FWIW, my '87 Camaro had the same leak, the pass side carpet was wet with coolant. But things get worse for me because I had a shop replace the heater core. In doing so, they had to remove the valve cover to get at the hoses on the firewall, in doing that, they had to remove the bracket that holds the coil, and that meant removing two bolts that hold down the cyl head. The cyl head started to leak shortly after I got the car back. Yea, the heater core was fixed, but now I had to replace the pass side cyl head gasket!!!!!

The point here is check the work if someone else fixes your car. Find out exactly what they did, and use the proper torque on all bolts doing the repair process.

Re: New problem arised WTF??

Other than doing a thorough job of replacing the heater core, I can't think of anything else to look for. These heater cores deteriorate and start leaking. I had to do the same thing on a previous third gen that I used to have.
Make sure that your thermostat, cooling fans, and water pump all function properly.

Re: New problem arised WTF??

Hey after you get the heater core replaced and coolant flushed check the system for Electrolysis in the cooling system, Electrolysis involves an ion exchange between the heater core and engine coolant which can result in a breakdown of the heater core material. This is similar to the operation of a battery. I had a simlar problem on a truck I owned. Here are the steps to check for Electrolysis.
  1. To check for electrolysis use a DVOM set on DC volts. Place the positive probe of the meter in the engine coolant and the negative probe on the negative battery post.
  2. Adjust engine throttle to 2000 RPM to properly get coolant flow and true electrolysis voltages.
  3. If more than .4V is recorded, flush the coolant and recheck, be sure the water is desalinated.
  4. If there is still excessive voltage present in the coolant, check the engine to body/battery grounds. Also, verify proper grounding of any aftermarket electrical/electronic equipment which has been installed into the vehicle. Improperly grounded electrical devices can cause electrolysis to occur.
  5. If the condition is still present after the grounds have been checked, it may be necessary to add extra grounds to the heater core and engine. A hose clamp can be used to secure a 16 AWG stranded copper wire to the heater core inlet tube. The other end should be secured to an EXISTING FASTENER on the body sheet metal. Extra grounds to the engine should be attached between EXISTING FASTENERS on the engine and body sheet metal. Verify continuity of any added grounds to the negative battery terminal.
Hope this Helps

Mikey
