old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Jul 2006 Posts: 327 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2006 Posts: 327 | Its such a coincidence that I have being loosing coolant but there was no sign of it coming from the heater now there is .It just started leaking today from the bottom inlet pipe I think.... That is my question number 1 is the inlet the hose coming from the water pump,or the top hose from the thermostat housing.. I know the core can be repaired.. Question 2 while I have the heater out of the truck can I put a plug in the inlet hose and outlet hose with out the hoses exploding so I can drive the truck and at the same time Shall I put a shut off valve on the inlet hose when i put it back on. Does anybody have a drawing of my heater my manual doesn't show it...thanks again .Peter | | | | | Joined: Aug 2005 Posts: 1,186 Shop Shark | | Shop Shark Joined: Aug 2005 Posts: 1,186 | Hey Peter, Just loop one of the hoses to the other port on the pump making a circle. Won't hurt it at all. Then get your heater core rebuilt, you might want to rebuild the control valve while everything is out.

So you say take the bottom hose to where the the top hose comes from (the thermostat housing) and attach the bottom hose to that housing...Good Idea | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | The hose connections on the water pump are intake connections. The water pump forces water into the block and the water flow exits from the head at the thermostat housing.
Only Canadians in BC can drive around in winter without the heater! | | | | | Joined: Jul 2006 Posts: 327 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2006 Posts: 327 | Fred Its summer here in BC now Has it stopped Snowing back east yet???? Peter....
So what you say above is what I wanted to know The inlet is the top fitting on the heater and the bottom fitting is the outlet.
What about my idea about a valve when I don't need the heater will that work if I turn the coolant off to the heater???

It will stop the flow through the heater and cut down on the amount of heat it produces. Some say blocking the flow completely is a bad thing for the core. It really doesn't matter which side the valve goes on as it still stops the flow.
Back east here, it was a day of shoveling yesterday!

They are probably the best and the only ones who could/would repair my circular core. | | |
