heat

[n8murphy]

Ive git some decent heater boxes but no cabin levers. Should i put em in place of my jpipes and wire them open. Ive got an 1835 with amerged header and have no cabin controls in my 66. Is it worth it to put them on and have them stay open. I havent bought any hoses or a different lower tin yet. Without a thermostat or controls will it even generate any heat?

that would be great in the winter, but it will roast you in the summer especially your ankles. I guess it depends if you plan to drive the car all winter. I left the heater boxes on my car, but I wish I put J tubes on since I won't ever drive my bug in the winter. If you plan to drive the car all year round, it isn't that hard to route cables to operate the boxes. Heck, even if you could temporarily route some wire through the tubes and connect it to the heater boxes so you could have some control to open and close.

will i get adaquate heat without a thermostat? i drive it all year ill just close em from underneath in the summer or rig something up. I was trying to figure out if it was worth hooking upor not. im looking for a gas heater but they are pricey.

I don't have a thermostat and my heat works ok. Running cables is really no big deal and they are cheap enough.

The thermostat dosn't have much effect on cabin heat. The heat is generated from exhaust gas temperatures and the thermostat just controls cooling air past the cylinders.

Having a thermostat really insures the cooling system is working properly for the weather conditions and the engine conditions.

You really need to run ALL the tin in order to properly manage the airflow needed in the cooling system.

You could install the heater boxes and wire them open, but then you have no control over the heat being generated in the cabin other then opening and closing the windows.

Why not replace the heater levers? It sure would be easier to deal with the heat demand if they were there.

The air-cooled VW's thermostat served only one purpose; to ensure quick engine warm-ups. It does not control engine temperature, it controls warm-up time.

The engine will eventually come up to operating temperature without a thermostat, but running at sub-operating temperatures isn't good for the engine.

The thermostat's flaps, located in the shroud, do help properly control the flow of the cooling air over the heads and cylinders. Even without a thermostat, they are necessary for optimal cooling.

I'm wondering if your thermostat is properly adjusted?

I'm thinking we'll probably have to agree to disagree....

i dont have one and no flaps ive got a merged header and whatever the po left on the car. i dont even have arear tin with holes. so i need tubes i need to put my boxes on take my jpipes off and it doesnt have y pipes inside under the seat either or levers or a lever mount. i dont mind putting theese all in but its my understanding the thermostat keeps the engine within operating temperature so if im driving around in the snow its not gonna generate the heat neccecarry to heat the cabin with all that tinware (thermostat flaps) missing? i could be wrong thats why im asking. its alot of little shit to source if im not gonna get the payout of adaquate heat.

if you dont have one is your cabin heat compromised? I mean the thermostat and the flaps i have niether.

I think someone already said this here but..

1. If you don't have a thermostat or the flaps your engine (heads, cylinders, oil) will take longer to heat up becasue there is no restriction - the fan blows cold air immediately down on the cylinders as soon as you start the engine.

2. The source of heat to warm the interior of your car comes from the exhaust pipes of the front two cyilders. They get real hot real quick, so, if you don't have a thermostat or flaps you still should get heat assuming you have the fresh air hoses and heater boxes - BUT...

3. When it's cold outside If you don't have a thermostat or flaps a lot of the air that could be blowing across those very soon to be HOT exhaust pipes (heater boxes) just blows out the bottom of the fan shroud and over the cylinders that realy don't the need or want it.

4. Not running a thermostat or flaps is done all the time and the warmer the climate you live in the less it matters - but it still matters. If they were not needed VW could have saved a ton of money and not included them but their reputation for building such a reliable car would have never been realized. They have way more to do with helping your engine last longer than keeping you warm.

Thermostat and flaps, run them or not, it's your choice.

Are replacement thermostats readily available?

Plenty of used and new-old-stock thermostats for sale in the Classifieds. NOS ones are getting pretty expensive though.
