Hi,
I have a 96 chevy s10 pickup with a 95 chevy blazer motor in it and I have no heat! The heater hoses are not getting hot except for residual heat from the motor. There seems to be no water circulating in them. The truck and intake are from a 96 and the block is from a 95 I have a 95 water pump on it and I am not sure where the heater hoses are supposed to be. I do not know if I should get a 95 intake instead of a 96 or What.I am lost!!! Any ideas on what to do or where to put the heater hoses.
Thanks for any help in advance<

So you have no neat in Central PA. When you drive to Eastern PA do you have heat? Sounds like you need to flush your heater core. If you do a quick search you'll find the guide for doing it. Basic method is just disconnecting the heater hoses and connecting a garden hose to blast out whatever is clogging the core.

 

if the hose isnt hot the heater core isnt even getting fluid, hence the problem lies upstream.
