What is wrong when your heater is blowing radiator fluid inside on the floor and out of the heating vent on a 97 Jeep Wrangler Sport?

The heater core is leaking. GEt a manual from DISCOUNTAUTOREPAIRMANUALS.COM and replace it.

What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?

Because your jeep wrangler is over heating, you must have a sensor in the dash not working If that smoke is steam, the heater core is leaking and in need of replacement.

it could be a couple of things you could have a bad thermostat or a bad heater core

Because you don't have enough coolant in your radiator.

One reason your home electric heater is blowing cold air is the heating elements are burned out. A bad thermostat may also be the problem.

It would be best to disconnect the coolant lines and flush the core after the radiator flush. This will clear any sediment from the core.

check the coolant level, or, possible stuck thermostat.

The water pump on the engine circulates coolant though the engine, radiator and heater core (which is usually located under passenger side of dash). The heater core looks like a small radiator and once the engines coolant starts warming up thr heat can be spread by the blower motor mounted to the side of the heater core. Voila! Hot air blowing out of whatever vent you choose.

Only the fan is working, there is no gas burning (gas heater) or the electric heating element is not working(electric heater)Answeris it electric gas or oil Its gas.

Check the radiator for full coolant. Check the engines water pump and thermostat, as the engine coolant carries heat from the engine into the heater core.

It could be the heater valve which is located under the hood to the passenger side down below the radiator and fan units.

It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.

Its your Heater core if it smells like a syrupy sweet smell if not then its your thermostat

The heater core could be bad. Or, as was my case, you may have issues with your radiator. If the radiator is cracked and is not able to generate enough pressure the heating system will not function.

No. The thermostat controls the flow of water through the radiator, not the heating core. Using a thermostat with a higher temperature rating delay the opening of the thermostat (and the flow of water to the radiator) until that higher temperature is reached. This will cause the coolant to run hotter.

it is essentially a tiny radiator. hot coolant goes in and heats up the fins in the heater core and your fan blows air through the heater core thus heating up the air and you.

User Avatar

well you could just turn the heater off heater blower ---- If it is a car heater then check your coolant level. the heater is driven off a heat converter that is fed by the radiator system. When the coolant fails to pump round the radiator system the car internal heater doesn't work. Driving without coolant in the system will result in the engine overheating and seizing.

This would indicate that the system is low on coolant when the gauge is hot. Not enough coolant to service the heater core.

Nicrome wire is used in a heater as a heating element.

User Avatar

Your cooling system is empty of coolant and you must have a large leak somewhere.

User Avatar

The heater core is part of the heating and cooling system, and it is the circulation of the radiator fluid that supplies heat to the core. The water pump on the car is what is responsible for the circulation of radiator fluid.

Make sure you have enough coolant in your radiator. The radiator is the thing in the very front of the car, the very front of the under the hood area.
