heater core

i was thinking if it had a larger area for the fan to blow on that it might be warmer. like i said, it was an idea.

Well, it won't do much good. Hate to say the setup the cars currently have is about the most efficient way to heat. And not that effective on the vics. The heat in my car is rather lacking. I'm glad I don't drive it much in the winter.

My car pwns with heat. Give it like 5 minutes or so and you get glorious hot air. :p

My car has decent heat within 3 minutes of starting (On a cold day), and a few after that it will melt your face off. Plus I just set to 75 on auto and I never really have to bother with a thing. I should check to see the highest temp I can get out of the vent, anyone ever checked to see?

I have gotten as high as 140. Also be careful heater core r & r has caused broken limbs and other injuries

Which is why I said to chock the wheels and put the e-brake on!!!

just stick your heat on vent and it'll blow out warm air from the engine bay and outside. the heater core isnt really neccasary. and it wont even change your coolant pressure.

Yeah, that shit don't fly around here. Gets down to negative numbers here.

Wouldn't work here either, doesn't go into the negatives a lot. But it gets cold. Needa heata? Ya Needa heata core. And since I've replaced mine, It's been perfect. Keeps the engine cool too. (til I get a fan clutch)

Please keep silly crap like that out of the tech forums.......

A lot of the poor heat has to do with what thermostat is in use. Colder than stock thermostats results in less heat. I got much better heat when I was running a 195, but my coolant temps were usually 200-210 even in the winter. I run a 180 now and it hovers around 195. I suppose its also entirely possible the gauge is out of whack, its a cheap thing. Heat is OK this way but not blistering hot. Clogged heater cores will also put out lousy heat, just because coolant isn't passing through the whole thing efficiently, and that scaly shit that forms inside the tubes basically insulates the hot water from the metal of the core.


Air leaks will suck a lot of heat out, and base models had less noise (and by extension, thermal) insulation so you lose heat that way. Wagons have probably near double the interior space to heat, but exactly the same heater system as a sedan so they pretty much suck in cold weather. If you live where its really ugly cold and the heat output isn't enough, basically the best solution would be to treat the car like a house. Seal up air leaks around the doors, and insulate where you can. Can't get really silly, but adding a layer of padding under the carpet won't hurt, and a layer above the headliner. Replace the deteriorated paper behind the door panels with a plastic or maybe tyvek or something that won't be as leaky, replace any missing grommets in the firewall. It won't cook you out but it will help.


And you people have nothing to complain about shit heat. I drove a 73 Beetle for years. That is a vehicle with a piss poor heating system.
