What does this mean?

When a heater core is bypassed? Thanks.

That means no coolant flow to the heater core, no heater. Quick fix for a leaking heater core, when selling a vehicle. [img]/ubbthreads/images/graemlins/no.gif[/img]

block off the hoses that go to the heater box. I used to put wooden dowls in the hoses in some of my show cars to make sure that the heater core would not leak into the interior. [img]/ubbthreads/images/graemlins/scholar.gif[/img]

Just make sure you sterilize your tools before you perform any bypass [img]/ubbthreads/images/graemlins/scholar.gif[/img]

I've *heard* of some people by-passing the heater to keep as much of the heat away from the intake and fuel lines as possible. The stock fuel line on our L-72 cars runs right over the top fo the heater hoses, sucking up heat...

That's true if you had to keep the stock looking appearance of the engine , then that suggestion of T.Billingen would come into play-then your heater hoses would help insulate your fuel lines from intake manifold heat to a degree.----------JoeG [img]/ubbthreads/images/graemlins/biggthumpup.gif[/img]

I am possibily going to to buy a 1969 Chevelle with a heater core bypass. How would you recomend fixing this problem?

Thanks very much!

I guess it depends on how it's "bypassed". You can plug the hoses as stated above, you can plug the fittings exiting the pump (with small freeze plug type fittings), or you can eliminate the hoses altogether.

Or...you could be like Pete and not worry about the heat (or lack of it!) and let your car idle in the staging lanes, TRYING to build up what little heat the alloy won't dissipate, all while I'm dumping ice on my intake! [img]/ubbthreads/images/graemlins/grin.gif[/img]

All those options Chevy 454 mentioned are reversible --depending on which,would determine the effort involved----as far as heat, those fellas up north have thick blood--so you may want to wear long-johns during those crisp mornings of northern winters, while waiting for your car to warm your privates.

Best way to keep your fuel cool is to wrap aluminum foil around the fuel line and use a cool can. (I used a quart can coiled some a longer fuel line in it and filled it with ice. That was pretty effective. Sure kept the gas from purculating! [img]/ubbthreads/images/graemlins/[/img]
