No Heat

[ircwet]

Well upon my drive home I encountered having no heat. This is ONLY a assumption till I tear into things tonight. My question is there a vac pod that will divert the coolant into the heater core. I know that my 4.3 astro has one right on the housing. I do not see one on the Ty. I can reach down and feel the heater core and it is compartment warm, nuthing else. Since they replaced the heater core it gets no heat.
Thanks

Re: No Heat

When you move the hot / cold selector lever, do you feel any resistance? There is a cable that runs a door in the airbox to open or close it depending on whether you want hot or cold air.

Re: No Heat

There is no heater valve on the coolant flow, just a door inside the heater box. Like Vermontty said, check that cable - you can see it move by taking out that small plastic cover at the rear of your glove box. Also, another check is to feel the heater hoses by the blower motor under the hood to see if they are both hot. If they aren't you have a blockage in the heater core or those lines. Good luck, and let us know what you find.

Re: No Heat

I can see the cable open and close the door....there seems to be no FLOW at this time, I will remove tstat and see about blowing air and check for heater core blockage. Was just told that heat never worked since new heater core...tstat not opeing in my opinion. Any1 have a exploded shot of the cooling route. Let you know thanxs

Re: No Heat

If the thermostat was not opening, you would have an overheating truck. A good idea was mentioned above; feel the heater core lines when the truck is running and see if they are hot....

Re: No Heat

Well problem solved....I removed the hoses off my heater core to try and see if it was clogged. Sure as sh*t is was. I was thinking WTF it was just replaced before I bought it. But then was told it never had heat when it came back ( being it Cali I can only assume heat was never turned on). Well after 4 hrs of hell replacing the heater core I decidec to chop it open and see if it was a clog from bars leak or sumthing in the system. Come to find out the inlet tube was pushed all the way in to the back of the core and soldered in...NO CHANCE of ever flowing....nice to see the fine quality control of replacment parts....prob made in Mexico......Now I have heat !!!!

Re: No Heat

Weird. As stated above water -always- flows through the core. It's the damper that you move that controls heat. Now you can say you belong to "I've changed my heater core" club.
