I put mine in on the radiator end but shouldnt make any difference .The engine temp never runs hot in traffic like it did before i added the brass plug with a 3/8 hole drilled in it Carl

Carl - did you mean 3/16?

Thanks

It will make no difference which end of the bypass hose the restrictor is placed. Water flow starts at the water pump side so that would be the logical choice if you had to pick one end over the other. And Carl did mean a 3/16" or smaller hole.

Sorry, i did drill a 3/16 hole not 3/8,finger got ahead of my brain Carl

this hose is like my, um, never mind!!! (real short so I can't see it making a difference)

Hey guys, I've just found this thread, I've got my motor out for a rebuild and would like to know the reasoning behind putting the restrictor in the bypass. I don't seem to be able to find the original question. RodL

The restriction forces more coolant through the rad rather than allowing it(hot uncooled coolant)to circulate back into the motor-therefore it should run cooler.You can't completely plug the bypass hose but that restrictor will allow enough coolant through with the 3/16 hole.

  

Whoa, putting the plug in the bypass hose is only part of the equation. You may want to consider using a modified Robert Shaw thermostat (or Mr. Gasket equivalent) also.

A friend of mine closed up the by pass completely and t didn't seem to have any adverse effects. He has driven the car all over the US without any problems. Him, I and another went from the east coast to the west coast and back w/o any heating problems. I'll bet he has put on 40,000 miles on his Yblock
