Heatercore video needed!

Flushing out the crusty old dexcool this fix will last.

alot of people dumped the dex-cool out of the 3800 series engines because the dex-cool would eat through the gasket for the intake manifold and if you're stuck in the middle of upstate Montana your roadside gas station probably doesn't stock dex-cool and dex-cool and con green can't be mixed

HEY! It's that guy! Thanks for that. Always a good time hearing it.

Thanks Eric for all that you do. I didnt know the tricks of flushing the radiator,but thank you. Thanks for taking care of the customer,and you always do a good job!

I have a shameful confession: I want to blow out a heater core to see if crud comes out. LOL Alas, I'm just a computer geek and not allowed under the hood for any reason. 😑
That said, Eric, I absolutely LOVE your channel and enjoy watching a professional do his thing.

Was wondering if you ever use airlift coolant tool? Whats your opinion on it good or bad

Hiya S.M.A.R super cool video with loads learnt so please keep them coming GL&HF coming from Dulwich London England(✌peace✌)

What is wrong with dexicool just curious thanks

The question, the comment, it’s got the big THREE EIGHT, she’s got the windshield, the hob in the knob. She’s a runner folks 🤷‍♂️
Question, what does PRNY stand for Mr. O.? I’ve tried lookin it up but it’s been buggin a fella for months

Great job on the coolant and changing out the thermostat. Remember if we can’t do it you can ! Lol 😂

I miss my '95 Buick Ultra supercharged. Almost as much as my mechanic does…..

I thought I heard something about the age of Buick drivers in there somewhere. I laughed right out loud. (Oh, it's LOL now for those younger people.)

50+ years ago I worked in a radiator shop, removing/installing radiators and heater cores. Now and then we'd get a car that needed an engine flush. They were amazing as the water would come out completely black. After several blasts it looked much clearer.

Aren't you going over a little overboard just the flesh out of heater core a job that probably cost $60 is costing the guy by 400 now

Great job on old iron….LOL

where do you get that flushing gun thinghy?

I've always done my coolant flushes by:

Pop the upper radiator hose, run it to a bucket.
Drain the radiator itself to a pan, cork it.
Drain the overflow tank.
Fill radiator with distilled water.
Open heater fully.
Run engine until the thermostatic relief valve (what they keep calling a 'thermostat') opens.
Keep adding distilled water until the water into the bucket runs clear.
Cut off engine.
Drain radiator and cork, add coolant concentrate until you hit the 50/50 point for the car. If you can't add enough, start the engine, drain out a bit more distilled until you have concentrate right.
Reconnect all hoses.
Fill overflow with 50/50.
Start engine.
Keep adding 50/50 to radiator as it refills the upper hose. It doesn't have to be perfect. As long as it's at least 40% coolant, you're good. If you hit 60% coolant, you're still okay. You can do a drain and fill after a year with 50/50 mix. If you keep up with drain and fills, you'll keep your fluid fresh.

Caveat: Some systems now are built where you HAVE to use a machine to drain and fill. (Ford trucks). Others, like the Mazda 5, have the drain hose _partway down the side of the radiator_. You'll need to cork that so that what you pour into the radiator cap doesn't come straight out. (if you have a new hose you're going to install anyway, just cut the hose in the middle, one side to pinch off, the other to be connected to go to the bucket)

You will go through a lot of distilled water, but it's not like you're going to do this monthly, or even yearly. This should be an every three years type thing.

You can do the flush with distilled and premix. Do the same thing as the distilled, except keep pouring in the premix until the water coming out isn't clear. (Or you can use the premix in place of the distilled water, but that's a bit more expensive than using distilled to make sure everything flushes out clear)

Wondering if anyone else puts dielectric grease on hose's to prevent them sticking to the housing on the thermostat and other nipples ?

I need to flush my house. I have to wait until springtime. $2200 later, It's good enough for now. The plumber got the heat up to 69.

Could you do a drawing of the engine cooling system on where the water and airflow goes and are there. Any internal parts that could be at risk if not done properly? Andy Uk

Awesome job sir

As long as the heater core not leaking and flushing it works what's wrong with year after year I had a 2003 S-10 I had to flush every winter for 7 years and it worked great .
