cooling system maintenace to do list

Truck was heating up a bit last summer, was a hot day pulling a pass, but more than i remember it doing.
So was thinking about pulling the radiator. I would clean it inside/outside. Flush out the 20 year old fluid.
first question:
Before i pull it, should i put in any chemicals to clean the system? what would you recommend? I've always wondered about something like CLR and just run for a 15 minutes or so. Or just pull the radiator and soak it. I did install a coolant filter a few years ago.
thought i would pull the oil cooler to inspect it also. I've read some about clogging issues. Don't seem too common, but while i have the coolant drained.
T stat isn't too old, but would be a good time to change it.
Anything else i should do while got the coolant out of it?

I remember seeing something posted here about flushing your cooling system. I use the powdered Cascade dishwasher detergent in mine, works great.......

Re: cooling system maintenace to do list

I had a similar issue. And decided to clean and upgrade my system. I found that there was caked through the cooer and a third of the radiator. Iím surprised I didnít have more of an issue. I would replace your water pump with the Navistar pump. It has a built in filter head and you can use chemical or non chemical filters. For cleaning the system use a de scaler. While you have the cooling system drained take the opportunity to change your upper radiator hose to the one that routes behind the serpentine belt instead of through it. Change your t stat to a 205. And use RED coolant. You may need a t stat housing mine was not reusable.. I bought the billet Aluminium housing.

If the water pump is not leaking I would leave it alone. The upper radiator hose goes above the belt, this is a OBS and not a Super Duty. But I would replace all the hoses anyway. The 205 or 203 thermostat is a lot of hype. I have ran a 203 one now for 4 years and the only benefit is that the coolant gets hotter. The stock 195 works just as well. Red coolant is a ELC coolant and is not compatable with the injector cup sealant. Some say it is OK some say it isn't but I don't want to have to replace the injector cups just because the sealant failed because of the coolant.

Iím a tech for navistar and I can say through experience that red coolant will not effect the cups.

Re: cooling system maintenace to do list

I"ll check out that radiator good. i guess if it's got too much junk in it i'll replace it.
What is the benefit of the red coolant?
I replaced most of the small hoses when i added the coolant filter. kinda think i put a 203į stat in there about that time. Have to look at some paper work. But think i will get the big hoses.

Re: cooling system maintenace to do list

Navistar says not to use red ELC coolant in engines made before 2/2/99 with serial number lower than 940614.

The benefit of using it is, it is easier to maintain and it has a longer life.

If only those who knew what they were talking about replied, this thread would still be on page one.

Re: cooling system maintenace to do list

Thanks, I won't use the red. I would rather try to keep most of my cars the same.
