What causes a car to overheat and have no heat?

Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch. As mentioned above, this also restricts the warm coolant from flowing through the heater core which uses this to blow warm air into the cab of the vehicle.

Can a bad radiator cause no heat?

If your radiator is very low on coolant, you’ll get no heat. If your levels are okay, you either have a bad water pump or a thermostat that isn’t opening.

What should I do if my Subaru overheats?

KEEP YOUR FINGERS SAFE. The fans can come on at any time, the belts are spinning, and stuff is hot, so be careful. At some point, maybe after 5 minutes, maybe after 20 or more, the thermostat should open, and you should see circulation. Top off again.

Why does my Subaru heater blow cold air?

Anyway ever since then it was working fine no issues, then again just recently the car over heated after putting my foot down and the heaters inside the car blew cold air. But as i let it cool and then drove off slowly the heaters kicked in and the temp stayed normal until i got home, no issues.

Is there a problem with my Subaru Impreza?

Subaru Overheating!!!!!! Right I have a problem with my impreza (2003 blob eye with 59k miles on clock), there seems to be an intermittent over heating problem. It started when we had severe snow/icey weather, the car was working fine but all of a sudden the temp guage jumped to just under the red.
