    2000 LS V8 has rattling and knocking sound

    Joeger I seem to get hit air most of time from passenger side and cool to cold air on drivers side. I don't think their are any leaks as I no longer need to top it off so I think all the air is out. What causes cold air to blow on one side.

    2000 LS V8 has rattling and knocking sound

    I apoligize if I dont respond fast enough but my computer is not the best. I believe I have addressed the cooling system and have taken air out. I have re-added coolant and topped it up. I dont believe its leaking as I no longer need to add more coolant. Plus it seems that all hoses goping into...

    2000 LS V8 has rattling and knocking sound

    I am still getting some heat intermittently on passenger side but cold air on drivers side. Does this mean that the DCCV is definitely at fault. Is there anyone who can diagnose this for me.

    2000 LS V8 has rattling and knocking sound

    But how can a small air pocket stop heat from coming out. Does anyone think its something else.

    2000 LS V8 has rattling and knocking sound

    I added a bit but not that much. It can't be be low coolant as it took very little to top it up.

    2000 LS V8 has rattling and knocking sound

    I also checked fuse number 1 which looks to be the small 10 amp fuse and not any of the big ones. If I am incorrect with that then can someone please let me know. It looks like all connectors are hooked up.

    2000 LS V8 has rattling and knocking sound

    I don't think its air in the system. All hoses on the car are hot including the ones going into the firewall. I let air out through the valve in the hose and added some more coolant yet its still got no heat. The compressor for the air conditioner is also not turning on. Does this still sound...

    2000 LS V8 has rattling and knocking sound

    I replaced the other coils and I would say the car is now running 97% smooth. I think it might have an exhoust leak coming from bottom of car. But right now the frustration lies with trying to finally fix the normal heat issue. As has been posted many times before on these forums, I am getting...

    2000 LS V8 has rattling and knocking sound

    Well I replaced coil 7 and all the other coils on that side if the engine as well as 7 out if 8 spark plugs due to one if the new plugs breaking when it fell on the floor . The service engine light has now gone away by itself. But unfortunately the car still sounds tough and runs and sounds like...

    2000 LS V8 has rattling and knocking sound

    I think you are right. The heating and air-conditioning were working ok before the engine was pulled and thats why its maybe not the DCCV. But the air-conditioner compressor is also not working . Can you tell me exactly how to bleed the cooling system to a T with detailed instructions

    2000 LS V8 has rattling and knocking sound

    Joeger, I appreciate yours and others responses. I got some replacement coils as the code shows misfire on number 7. I will also replace all of the spark plugs to go with it. But as to the no heat issue, I notice that more hot or warm air blows from the right passenger side than the drivers...

    2000 LS V8 has rattling and knocking sound

    We again the people posting on here are smarter than the idiot repair shops. The problem was with another part that broke with the timing chain assembly. I ordered a complete new timing chain assembly and they put it in after they stupidly removed the whole engine from the car because they...

    2000 LS V8 has rattling and knocking sound

    The bottom end always had clean oil and after hearing all the posts on here I feel really comfortable that the bottom and should be ok. Now my only question is does anyone think I have to do a valve job.is there a chance that the bells hit the Pistons or does it sounds okay. When I drove it I...

    2000 LS V8 has rattling and knocking sound

    I appreciate all the expert opinions on here. As I said it turns out that it was the guides on the timing chain as per what the idiot mechanic told me. This comes after they pulled the engine and already replaced the tensioner. But I need help now to decide what to do. Seeing that there are no...

    2000 LS V8 has rattling and knocking sound

    Are you saying that their are no bearings that you can buy for the V8 2000 LS. I see bearings listed for the V6 2000 less engine, but I don't see anything listed for the V8. How was that possible

    2000 LS V8 has rattling and knocking sound

    Well it looks like everyone on this board knows more than these mechanics. As the problem was within the timing chain cover. But they needed the Pollote the engine to see this. My question now is, seeing that they pulled it out should I get it freshened up. Does anyone think that it needs new...

    2000 LS V8 has rattling and knocking sound

    So what your saying and what everyone else is saying, is that there is no way that sound is coming from the bottom of the engine. To me the sound sounds the same as if when the tensioners broke. It is definitely coming from the top. But this Indian mechanic is either stupid or is trying to scam...
