To everyone.

Having a heater core problem?? Leaking?? Cracked...ect. I know it is very expensive to replce a new one ... approximately 140 usd.

I just found an alternative way to save big bucks, yet still get the heat for winter.

So far i have spent 20 cad for materials and 2 man hours to complete my own homemade heater core.

material.

1) 1/2 inch copper tubing
2) 1/4 inch copper tubing
3) flux
4) soldering torch
5) solder.

Instructions:

Cut out four 1/2 inch copper tubing ( use your exisiting heater core as measure template).

drill 10 holes on all 1/2 tubing, space evenly.

cut 20 x 1/4 inch tubing and solder all into the 1/2 tubing.

Capped the end of the 1/2 tubing.

the coolant should flows freely.

I live in Vancouver, is cooler here, and my experience works, dont' worry about adding fins on the 1/4 tubing. The tubing itself radiant heat very well, of course fins will definately increase efficnency of the core.

Advantage 1) save $$ 2) guarantee no leak yet rugged radiator 3 ) fun to build based on plumbing knowledge.

Disadvantage 1) not as efficient as the original heater core, 2) it is homemade. ( you can increase the efficiency by stagging the core up to the maximum space inside the heater box. As long as the air flow is not block.

Hi,
Excellent work, most of the stuff on this site is somebodys innovation!
I'm sure it'll help someone in another country where parts are hard to find / expensive.

Thx, for the compliment. Apologize for my bad English which may confused some of you.

Any questions please ask. I worked in the Aviation Turbine industry. I have lots of experience in machinery, hydraulic, welding....etc.

Hope my knowledge can help everyone
