Another 2 evening project for my 65 Fastback with the 200 inline 6. I removed the heater hoses,
back and forward flushed the motor and radiator, bought all new reproduction radiator and heater hoses and tower clamps. I thought it would be a good idea to replace the heater core at the same time.
Holy moley, the housing that surrounds the heater core was full of twigs, leaves, you name it.
I degreased the engine and compartment and will install everything tomorrow.
I have some "need to know" questions. Which direction does the thermostat go?
The spring with copper end twords the radiator or motor? When installing the gasket,
do you put the thermostat into the water outlet first, followed by the gasket?
Does the gasket adhere to the water inlet or the block?
The previous owner did a lot of wierd things and I just want to do it right.
He used the Permatex gasket and not the Felpro that I bought with the thermostat.
Any preferences? Use both? Best way to apply? The wierd things I'm most concerned about
is that there are two inlets to the block for the heater hoses to go to.
He has what appears to be a galvinized pipe coming off both sides of the block,
with a 90 degree elbow which, tapers down to a threaded end to receive the heater hose.
Both the elbows had a blockage. I managed to clear them. This may have occurred during the flush,
but I'm not sure. A considerable amount of rusty scale is evident from what I can see looking into the threaded end of elbow. The heater core was bleeding out reddish orange water after it was removed.
I'm glad about removing it. How in the world do I, should I, attempt to remove the elbows.
I'm so afraid of attempting to break loose (or literally breaking) either the straight pipe or the elbow.
If its caked with rust, how soon will it plug again? What did go into the block where this galvinized pipe comes out? Any suggestions? Can the heater core be bypassed? Could it affect the
cooling of the motor? I realize, there would be no heat inside. Its not an air car.
