Sorry to tell you this unless you have plenty of time and money and you can pull the dash apart, as they are a bugger to play with all cars are under the dash and you have to strip out the inside of the car like
steering /dashboard complets assy all wiring etc etc .
So dont play with it BUT if its leaking water into the car or pushing steam up on to the windscreen then you have a leak that CAN be fixed without touching it like a tin or 2 of IRON TIGHT/or go to the Cummings truck agent and get a tube of ALLORMORSEAL. its a radiator repair sealer on trucks and they also work in cars ,tractors etc.
Let me know how you get on .. RON

Film on inside of windshield and a sudden large coolant leak. Could this be the radiator or what else?

Coolant leak is likely coming from the heater core or coolant line to/from heater core.

The film on the windshield is antifreeze.

Diagram for heater core replacement on 1986 elcamino

Best to get a repair manual. You will need to remove part or all of the dash, since the heater core is inside the car on the firewall. An Autoparts store would have a repair manual for your car. In The Meantime: 1. Disconnect the heater hoses, at the firewall in the engine compartment. 2. Connect the two hoses together using a piece of tubing and a couple of hose clamps. (This will bypass the heater core, until you can get it fixed.)

Need to replace heater core

Very very big job. Only do this if you really really love your car. Here is the 100ft overview:

*Disconnect the heater hoses at the heater core inside the engine compartment. (recommend cutting the hoses and replacing with new ones)
*Disconnect the heater valve cable from the heater valve
*Remove dashboard (involves removing steering wheel/column, radio, glove comp, etc)
*Remove the heater assembly (big black plastic box behind the radio)

The core is inside the heater assembly.

Again, this is a big job, and it will probably be very frustrating at times (I know from experience). If you do not have a repair manual for the car and you think you want to try this...get the manual first!

Heater core removal on a 99 ford expedition

To remove the heater core on this truck the entire dash must be removed, the A/C drained, and the coolant drained, once the dash is out you can access the environmental station, which houses the a/c and heater cores. The heater hoses to the core and a/c lines to evaporator core are quick disconnect and require a special tool. After removing the environmental station, disassemble the station by removing the screws, then you will be looking at the inside of the station, the core on the left side is the heater, the door is the blend door, and the core on the right is the a/c core. Re-install in reverse of disassembly, fill coolant and charge a/c. If you are not comfortable with this depth of repair I would find a reputable repair shop in your area and take it in for this repair. Hope this helps, let me know.

Find out how to replace heater core in the front

The front heater core in your truck is inside the environmental station, which is inside the dash, the entire dash will have to be removed in order to access it, in order to access the heater core itself you will have to remove the environmental station, requiring the draining of the engine coolant and the a/c system. Your best bet is to buy a Haynes or Chiltons manual and follow the steps to perform this repair, or take it to your favorite repair shop. The core itself should cost about 60 dollars. I did my own and it took a good 5 hours to remove and replace everything. I hope this helps, let me know.

Windows get like a foggy film and smells like old antifreeze. i think its my heater core? its a 95 bronco & where is it located exactly on that model?

Dear Foggy Film......
You are correct!!! This foggy film is the result of the antifreeze leaking and then evaporating inside the cab of the vehicle. The heater core on this vehicleis located inside the evaporator case inside the vehicle's cab on the firewall up underneath the dash closer to the passenger's side. It involves about three hours labor to replace the heater core.This is a moderate to mildly intensive repair for the first timer..if you have any more questions then you're more than welcome to get back to me!!!! HOPE I COULD HELP!!!

Heater core

Hello there:
These are not hard to remove the hard part is to get the two halves of the box open they are sealed together so what you need to do is to get a really sharp utility knive and cut along the seam and then this will allow you to split the box and remove the covere so you can get to the heater core.
Once the repairs have been made make sure that you reseal the two halves so that no water or air will get inside ok.
best regards michael
