M1008 radiator replacement

[Enforced_Leo44]

Hi everyone,

My truck recently developed a radiator leak, I think it's some sort of hairline crack between the inlet tank and the core. Brought it to a local radiator shop but they couldn't locate the leak as it apparently only leaks while it's cooling down, they just gave me a bottle of "LiquiMoly Radiator Stop Leak Plus" and said "If it still leaks, shake this thoroughly and pour it in the coolant while the engine is cold"... and asked me 130 euros for this.

I've always been quite against these radiator stop leak products because I'm afraid that they could clog some coolant passages within the engine, so I'll probably bite the bullet and get a new radiator...

I'm from Italy so my parts choice is pretty limited, RockAuto would be my best bet, so I looked on it and found a OSC 850 radiator, anybody has had any good/bad experience with said radiator?

EDIT: It's a 2 row radiator from what I read, I don't do any towing/pulling/heavy payload stuff with my truck so maybe 2 rows are enough

Thanks in advance,
Leo

Do not waste your money on a 2 row. Even without towing.

I would take it to another repair shop and see what they say.

If not, be prepared to spend some cash.
They still make the copper/brass radiator, but a lot of guys have had luck with other models.

Search or Looking back on old threads will show you the part numbers.

Leo,

slightly closer than US. Maybe this will fit your needs?

I tried the aftermarket 850 brass radiator and it was junk. I have an aluminum one with plastic tanks that is much better. Lately there are a lot more aftermarket options including welded aluminum units.

Any information on that aluminum radiator? My 1008 needs one as of yesterday. Are these 3 or 4 core?

Hey there, the OSC 850 from RockAuto (the one I bought) actually has 3 quite large rows, even if it’s sold as a 2 row

You will have to modify the upper supports a bit, the radiator is slightly shorter height wise, and the fitting are somewhat strange, they include some adapters that are finicky

Other than that, it works as intended, the temperatures stay down, I still have to test it in hot weather though

PS the one I bought is all-aluminium, no plastic side tanks

So far so good with this one from Jegs.
CUCV radiator

They are made in the USA by TSM.
Thermal Solutions Mfg

One arrived damaged right off of the Fed Ex truck, so it was returned.

That looks like a good choice!

If you order one, make sure you open and inspect it while the delivery driver is there. Any damage, refuse it.

Out of 4 shipped to me, 2 were damaged. Hopefully the 5th time will be intact.
