Question about Chevrolet Venture

1 Answer

How do you bypass a heater core on the 2000 Chevy Venture. It has a rear and a front heater core with a 3 way T outlet connecting several hoses and more than two hoses that go into the firewall since it goes back to the rear heater core as well. I was told it cannot be bypassed any suggestions?

    That seems like the simplest solution and is what most people say, however how do you determine which ones coming from the engine are inlets or outlets. There are more than 2. As a matter of fact I just had a 3 way T outlet (going from engine and into two other areas of the fire wall) replaced b/c it broke.

    We had a guy at O'Rielly look at it and given that some lines from the heater core also ran back into the radiator from the core he didn't think it could be done.

    Are you sure for a vehicle that has a dual heater core we can just perform a simple engine bypass?

Yes it can be done. look at your engine on it there will be two heater hoses coming from the engine to the heater, disconnect those two heater hoses at engine, with heater hose and two hose clamps, get the hose and clamp first at auto parts, install one end and the other end of same hose, where you disconnected the heater hoses from the engine, you have just by-pass the heater, hope this was very helpful.

    In the hose your going to used to by-pass, cut it and install a T and hook the hose that runs to the radiator to that, no need to know which is inlet or out all going to the same place, back to the engine, no one way valve on it.

Rear heater core lines leaking near firewall


If the tubes going to the rear heater core are the problem , drain the system and replace the bad tube/tubes. If the actual heater core is leaking and you do not want to go to the expense of replacing it, unhook both tubes at the back of the motor , cut out a good section of hose and use it to loop/connect the outlet line and inlet line on the motor side (not the rear heater core side). This will bypass the rear heater core , the front heater core should be adequate to heat the whole car. If you have a pin hole in a section of solid (copper) tubing, you can cut out the bad section and reconnect it with some heater tube and two hose clamps.

My van is over heating there is coolant and water in the radiator it started leaking underneath towards where the front passenger seat


The problem sounds like either the inlet or outlet hose to the heater core is cracked or split. Or the heater core itself is at fault. Need to inspect the hoses from engine to the firewall going to the heater core for damage. If no leak from the outside then problem will be on the inside under the dash. Hope this will help you.

I have replaced the rad cap, water pump, thermostat and water pump heater on my 2000 Chevy Venture. The rad and heater core are good. The water pump heater was in for 2 days working great and now I'm...


first of all the water pump doesn't have a heater, all the water pump does is cycle water (coolant) throughout the cooling system, the heater is up inside the dash behind the glove box.

I would feel the two 3/4" heater hoses that run from the engine into the heater core, if both of them are hot (providing the engine is at full temp) it one is hot and the other is cold maybe the heater core is plugged.

Rear heater not getting hot after by-passing front heater core which is leaking.


Hi:
Your vehicle only has one set of connections to the heating system, and you disconnected them when you bypassed the heater core. There is not a seperate heater core for the rear heat, just ducts off of the front heat.

I have a heater core leak on my 2000 chevy silverado V6, is there an easy fix?


You can bypass the heater core, you just wont have heat anymore. On the firewall of the truck, behind the engine, you will see 2 rubber heater hoses that go into the firewall. They attach to the heater core. Disconnect them and get a plastic connector, and connect the 2 hoses together with clamps to hold them down. This will stop coolant from going into the heater core, and no more leak.

I have a 2000 Chevy Cavalier the heater and the rear defogger doesnt work both quit working at same time


Try taking a hose off the heater core for the front heater to see if your core is blocked, this might indicate a core cleaning.  As for your rear window defogger, the wire that usually feeds the  heater might be severed or cracked and you might not get a proper contact. Take the small plug off the heater strip and stick an Ohm meter on it to see if you have an open or closed circuit.
