D9G Coolant flush recommendations???

I looked up some old threads and it seems cascade is what was recommended..... I will go ahead and do that..... Chime in if I should put the thermostats back in or not.... I am still going back and forth....And I will not clean my radiator with a pressure washer.... I do not want any leaks....

-x 200 on thermostats ! ! engines prefer to be at a steady temperature, as much as possible....not too hot, not too cold (think Goldilocks)

-i used a pressure washer on the exterior of my rad, depending on pressure output you need to be careful....not too close...don't bend the fins etc...it makes a HUGE difference when clean and proper airflow thru the core..

-Cat has recommendations for cleaners inside the cooling system, i seen some but cant remember offhand...

-dont' listen to Trump about injecting cleaners:flame:

Hi Team,
scans from a Cat Publication "Know Your Cooling System" Form No :- SEBD0518-01, Dated 1978.
There are later revisions but I feel that this one covers early style systems better.
Yeah, well, seven is out of place due to inability to load more than six scans at a time----

Everybody should Save these for your future reference.
Cheers,

Mine only had one thermostat, i put 2 new ones in and it gets up to operating temp much faster. Why wouldn't you put them in?

We used the cat recommended potion and got a fair bit of stuff out but ended up having to core it as per my other thread. We used about 3.5 bottles of the quick action stuff.

Make sure you get the oil coolers. We didn't take them off. We left one elbow attached ran water down and flushed it out that way.

Appreciate your reply.... I am going to fill it back up run it for a couple hours and then dump it again and do that 2 times... I will follow the steps regarding cleaning the radiator ect... I ordered 2 cat thermostats will pick them up tomorrow but will wait to install as I want it to be flushed multiple times...

It states 40 gallons and that means a lot of water and cleaner to circulate.... Will get her done... Thanks again...

Yeah, that sounds about right. Pressure relief valve is another cheap item that might be worth looking at changing or testing. I did that top hose and one of the bottom ones while i had the thermostat housing off and the thing drained, save dropping 40 gallons of coolant to change a hose in a years time.

That's pretty well all we did. Don't get too carried away with the dose of the potion, It's pretty expensive stuff but last thing you want to do is flush a hole in something. I think the instructions are fill, run for 2 hours and drop or something like that. There is a slow action (leave in for a few hundred hours) option too.

Taking the top tank of is troublesome. It can be done but you need to pull the radiator halfway out to access the bolts. Hopefully you don't need to go that far.

There is a bolt down near the oil filter that will drain the block.

Thanks for that I will find the drain bolt by the oil filters for the block.... I want to get as much out as possible... I have the 2 hoses that need to be replaced the one off the water pump that goes up by the fan and then the other closer 2 the fan same side as water pump... I agree better to replace the hoses now then meet the dump of 20 or so gallons later.... Will it ever end???
