Heater Hose modification??

I have been having some trouble with my sami running hot. The other day I was checking the heater hoses and I noticed that the bracket on the firewall that flips when you slide the hot cold switch on the dash and changes the path of the water was jammed and someone had taken it out of the loop. The switch used to cut the flow of water to through the firewall to the heater core or whatever, and now that it is gone I have a constant flow that cannot be switched. This wouldn't cause me to run hot would it? I would think it would make it run cooler, kind of like running the heater all the time. Any ideas?

no it will not cause you too run hot the only way it would make you run cooler is if you were too run the fan on it . i dont think i would do that in 90% weather LOL!

Re: Heater Hose modification??

I run my heater full blast when I am running on the trails, It'll keep the thermometer ehheh about 1/2 way, if no heater it'll go to about 3/4 +- a little.. Take the valve off, clean it out see if it still works (mine was frozen up kinna bad, fixed real easy).

Re: Heater Hose modification??

I removed that valve long ago. I have never known as samurai to be cold. [img]/wwwthreads_images/icons/smile.gif[/img] I replaced that valve with a flush valve. I can open up the coolant system there and connect a hose to flush from that end of the system as well as from the radiator.

Even in the dead of winter, as long as I have anti-freeze in the radiator, it stays warm.

Now, if yer heater core is plugged from rust or what have you, then there could be a prob. You can bu-pass your ehater core altogether and see if there is any noticable difference before yanking the core out for inspection. The heater core feeds back into the water inlet hose right next to where the manifold to heater hose exits the manifold.
