was the airbox cleaned after they installed the core? Antifreeze is sticky nasty foul S*^^T
cleanup is the key, also, does the "NEW" one leak? are the hoses good?
everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section for FREE...make copies of the right pages and fix your vehicle like a PRO! :)
Some coils are also coated to prevent corrosion and it is usually a little oily. This could also be what is on the windshield. If it is that, it will stop.
Could be the heater core.
The heater core is leaking coolant.
Sounds like heater core is leaking, replace heater core or bypass
Most likely a film on the inside of a windshield is caused by an engine coolant leak within the heater core.
The fastest way to defrost a windshield is to turn the defrost vent on without heat or simply open the windows. Another option is to warm the inside of the car by turning the heater on.
1968-1982 Corvette heater cores typically begin leaking due to a breakdown in materials dropping anti-freeze and coolant on your Corvette's carpet. This is not a pretty sight. Removal of the heater core takes place from inside your Corvette. First the RH side lower dash pad must be removed, then access can be gained to the inner heater box. Remove all ductwork (windshield defrost, floor duct, side ducts, etc.). The main inner heater box is supported to the firewall by 4 to 6 studs, these stud plates are riveted to the inner heater box. By removing the nut on the opposite side of the firewall the inner box can be removed from the Corvette. The heater core is mounted with straps inside the inner heater box. Once the inner box is removed from the Corvette, the heater core can be replaced and reassembly can begin. At this time it is also a good idea to replace all the seals in your Corvette's heater & air condition system. Seal kits for 68-77 & 78-82 Corvettes include ductwork seals, inner box seals, heater/ac flapper door seals and firewall mount seals for internal and external heater boxes. Replacing these seals not only improves your Corvette's heater & AC performance, but also eliminates air drafts which are common on all C3 Corvettes. From all of us at Zip-Corvette.com
Heater core is located inside the H/AC "suitcase". It can be a chore, but you're best bet is to remove the 'suitcase' and remove the heater core once the suitcase is on the ground.
The AC takes the moisture out of the cabin air and that helps clear the inside of the windshield from moisture faster.
if there is condensation on the inside of your windshield you can probably smell coolant as well. this is caused by a leaking heater core located behind the glove box in the evaporator case.
You first have to take the passenger side (bottom) dashboard out. You then remove (approx) 3 bolts from the inside and (approx) 2 nuts from the motor side. The heater core is inside the heater box. When the box comes off, you then remove the heater core from the box - after removing about 6-8 screws. It is more difficult than it sounds.
Finding coolant on the passengers side floor. Turning on the defroster and the inside of the windshield fogs up. Sweet smell of coolant inside vehicle.
Either the heater core is leaking, the windshield is leaking, or there is a leak around the cowl. If the water tastes sweet it is a leaking heater core.
The heater core is on the passanger side, located behind the bower motor housing on the firewall. If the car doesn't have AC it is not a difficult project. Remove the heater hoses from the firewall and then remove the screws that attach the cover to the firewall. The heater core rests inside.
Check inside the engine near your windshield if the water drainage holes are open
IT IS LOCATED ON THE PASSANGER SIDE OF THE VEHICLE, WHEN THEY DO LEAK THEY TYPICALLY LEAK INSIDE THE VEHICLE.
Why are there windshield wipers inside the car?
It could be that you have a leaking heater core, which resides inside your car. Another give-away for a leaking core would be a sweet smell inside the car and/or a sticky residue on the inside of your windshield.
They usaually fog up the inside of the windshield when defrost is used, soak the pass side floor with coolant and smell of anti freeze when operating heater in any mode.
I have 95 Trans Am with a LT1 corvette motor. The heater inside the car does not heat very well. I was told I could have some air in the system. Thermostat is new.Heater core hoses seem warm not hot . 90-110 using thermal gun on the out side of hoses.Back of heater core showed 115 deg. Should heater core be back flushed? Any ideas on how to get more heat to the driving area?
Windshield tranny inside the engine????? The windshield has nothing to do with the transmission, and they for sure are not inside the engine. But, I will say, go to your local Auto Parts Store. They can help you.
watch your coolant level because antifreeze is probably leaking in your heater core, another indication of leaking heater core is greasy film on inside of your windshield and it makes it hard to defrost.
Does the smoke smell sweet, does it leave a film on the inside of you windshield? If so, you have a leaking heater-core. $30.00 part.
Yes. That smell is the coolant being blown into the air ducts. You might also notice a slimy film on the the glass that is very difficult to clean.
You most likely have a leaking heater core, check you coolant level first while the truck is cool........
