I figured out how to flush the heater core with just tubing by removing the hoses that connect to it on the firewall and hooking up the tubes to the heater core, then flushing with water and finally replacing the water with coolant. I'm still working on the block but I think I can make that...

Thanks, I could definitely do that probably with rubber stoppers and my carpet cleaning machine haha I just want to know the job was done right. I've never had a good experience with taking any vehicle, even a 1998 ford ranger, to any mechanic. I suppose I could just take the LS to the...

Well. Finally got all of the plastic parts replaced. New intake manifold gaskets, new degas, the whole nine yards. When I was in there I noticed that it looks like the cooling system may be contaminated. I'd like to flush the whole system and backflush the heater core, but I'm not sure how to...

Got the water pump off today. The impellers and everything looks intact but the plastic on it was very brittle and came right off as I pulled it out.. I guess this would have started leaking within the next year or so. I'm sure this is the stock water pump and with 138k on the clock I can say...

Here's a pic of some of the metallic flakes I found in the coolant I saved. Its been outside so there's some bugs and stuff in there that did not come out of the radiator. The only thing that came out was coolant, some metallic flakes and very small copper colored flakes. There's not much of the...

I had a first gen before this car also. I got lucky with that one. The guy was in the navy and replaced the hydraulic fan and all the ball joints before I got it. I just needed a new ac compressor and a dccv. The old compressor was working but leaking oil. He didn't know about the dccv though...

Thanks for the insights! Its possible that the car was run with old antifreeze before I purchased it at some point. I bought it from a real estate agent that knew absolutely zero about cars. When I whipped out my scan tool in his driveway and started looking at the ball joints he thought I was...

I've tried to bleed the system several times now. It's not quickly overheating. Takes about 15-20 minutes with the heat on max to get to 220. Do you think there would be some coolant in the oil by now if the oil to water cooler has failed? Theres been no oil in the coolant yet and I've drained...

Thanks joegr! I actually was on the phone with the ford dealer just a minute ago about a water pump gasket. They have one for me. I'm not a trained mechanic, but i can follow instructions, and I have done extensive research over the last few days regarding overheating in general, and...

Thanks for the response milehighmickey. I do know my dccv is working. I just replaced it last month with a motocraft replacement and my heat/AC both work great. I'll check into the water pumps too. Probably time to replace them anyway. The coolant is already drained out so I'll just pop them...

I didn't order the bottle from rockauto because they didn't have motorcraft! Do you guys remember if before you replaced the degas bottle you could not get a steady stream from the bleeder at idle with the heat on max? Ive inspected repeatedly for coolant leaks. There's none. But there's...

Yeah I did have a problem with that when it got really cold out. I live in virginia right on the ocean so it doesn't drop below 40 too often right in my locality. I got the code twice because i actually had to go somewhere first thing in the morning on a cold day. It just cleared it self the...

The new one looked just like that. I noobed up and bought the housing with the thermostat already installed. I will admit that I've been battling myself as to if the new one is functioning properly. I think that it is and that there is a leak somewhere in the system that is allowing air in...

On a side note, looking in the coolant that was drained from the radiator I'm noticing some metallic and copper looking flakes in it. I'm assuming probably from the thermostat that fell apart.

That thermostat came with the car! I was comparing it to the new one and it did not look like the correct thermostat. The big spring was much longer than the one I just put in from ford. I guess I'll just change the whole lot of plastic components. I'm just not one to throw parts at a car and...

I'm going to find the paperwork and double check but I do believe the degas bottle was replaced at some podunk shop in newport news, va lol. It probably wasnt motorcraft. When my upper radiator hose cracked I could not see the crack either. Good point. I guess my biggest worry at this...

Here's some pics of the thermostat. It literally came out in pieces. The plastic clips in the housing that secure the thermostat in the housing were still there. I'm going to drain the coolant again and take the degas bottle off in a few and see what its looking like. There's no coolant leaking...

I did just replace the thermostat and the housing today. The old housing was still good, and new looking, but the thermostat fell apart inside of it. All the hoses you mentioned still look to be in good shape, still look new, and feel new even. I did not replace them, but comparing them to...

I did fill by the book. degas bottle first, then topped off at the engine fill cap. I was following the first gen instructions to bleed. I did not have that link you posted. The only thing I see that is different is for second gen (the link you posted) says to turn the heater to defrost. I was...

Hey guys I have a 2004 LS sport (3.9) that Ive owned for a couple of years now. She's been very reliable until now. The other day the LS over heated. The needle went into the red while my wife was driving it. So i trouble shoot and everything leads to the thermostat. I bought a new thermostat...
