Default Removing Heater Core

Has anyone removed their heater core?

I am debating if I want to pull mine or not in my toy car. I live in SC and if I move anywhere any time soon it will be Texas. So I am thinking I will not miss heat to much. The car is not a DD so I just will not drive it if it is below 50 or so. So are there any big cons to not having one besides not being able to vent out hot air in the case engine overheating? I am running a godspeed radiator and a coolant reroute, so cooling should not be an issue.

Kind of off topic, but would it be remotely possible to keep the fan, and then build a simple custom shroud that only routes heat to defrost vent? More work than just ganking it out on a pure toy car, but it would at least allow you to drive it in the cold if you wanted. You could lose a lot of weight and possibly a smaller blower as well, maybe one of those fresh air systems fans that are normally used to pump air into the cockpit. I dunno.. just thinking out loud.

Yes.

If you will not be driving it under 50 degrees I don't really see a reason to keep it.

Rain-x foggy wipes work really, really well.

When did you move to SC?

I will just pick up some of the Rain-x foggy wipes. I had never heard of them before and they seem like a perfect solution for if my windows do fog up.


I got down to SC in August, now seriously considering moving to Texas sometime next year. I just need to figure out where in Texas I could register a stripped car.

The only think you need in TX for inspection are lights and a pass on the emissions test.

The ac is responsible for defog more then the heat. If you really need heat, they sell little electric heaters u can plug in for under 20 dollars. Ditching the HC = one less thing to fail.

Is emissions state wide? The nice thing about SC is no safety or emissions.

No one gives a **** in Florida but I'm not sure if living here is worth lax emission laws.

This.

Some anti-fog on the inside and some rain-x normal crap on the outside. Done. Re-apply all of the time.

I've only driven the car in the rain once, and I didn't have any trouble with it fogging up.

If you don't keep up with the re-application the windows get the most anoying haze in them when driving at night.

Wherever you move, connect the "in hose to the "out" hose so that you maintain flow to the back of the engine.

I have a coolant reroute so isn't it all forced to go out the back of the head?

Depends how your reroute was done. Most reroutes that maintan the heater core still put the water through the heater core until the temperature rises enough to open the thermostat. If you block that flow, you could get hot spots.

Dependent on how your routing was done, you may be able to block the heater and simply put a larger hole in the thermostat flange.

Lars he suggesting that you keep the tube coming out of your spacer (that went the to heater core inlet) and connect it directly to your lower hose fitting. this way when the thermostat is closed, you still promote coolant flow.

That makes sense. I can loop it that way.
