DK45 radiator questions

[GMIslander]

Is the radiator on DK45 plastic or metal tanks. Mine needs repair and wondering how to proceed.
Musta happened last thing this afternoon noticed coolant running out of small maybe 1/2" nipple on bottom right of rad.
Brush poked up in there I expect.
I'm scheming how to repair it and I this is good place to start.
To cold and dark for me to crawl in there tonight old too.

My Dk40SE has plastic tanks.

A few years ago I let my wife do some brush hogging unsupervised, got an alder up in the fan and wiped out every blade on the fan.

I pulled out the entire cooling pack so I could have a rad shop check things over.

It's bit of a process to pull everything out, luckily for me it happened in the summer, wouldn't want to take the job on in the winter.

Plastic, good luck.

Plastic radiator? Mines metal. The fan blades may be plastic. Not the radiator

but mines a 2010 model. Ive never seen a plastic radiator… did not know it was a thing

The cores yes, but have you checked the tanks?
My little Kioti has plastic tanks.

Plastic
I'll have a new one the first of the week.
I can't be without the tractor so I'll install the new one and if my repairs are successful there will be a spare.
Thanks

Any chance that the tanks are ABS? If so, you may be able to do a hokey job of a temporary fix by cleaning the broken part surfaces really well and using ABS drain pipe solvent to glue them back together.
I used this to repair a broken handle on a shop vacuum hose about 10 years ago, and it is still holding together.

The vast majority of radiators have plastic tanks at either end of the core.

The tanks on either end are a high temp nylon, with aluminum fins. If its in the aluminum, its so thin, its probably not fixable. If its in the 'plastic', plastic welding is possible. Rads are expensive. Mine went on a 3yr old tractor from the inside out... strangest thing...

And to add to that - the ABS solvent probably will not work on nylon.

Friday took the day and went to the city to pick up the new rad. When I got there I noticed the box containing the rad was a bit damaged so we unboxed it to find the top tank was all busted up. The pressure cap and plastic flange it connects to fell out on the floor. A hole about the size of a tennis ball in top tank.
That was a nine hour day shot.
Took the damaged rad out yesterday took an hour and a half, a tight fit.
I would not trust using this repaired for the long term so I hope the next new one is in one piece.
You can see the split at the bottom of the small nipple.

That looks like so much fun! I suggest that you call and have them unbox before you drive to the dealership on the next one. I think I will do that also when I order delicate parts.
I replaced my rear window not too long ago, and the box was in bad shape, so the dealer too a look before they called to let me know that the window had arrived.

I Googled "plastic radiator repair" and there are products and YouTube videos that could maybe repair that crack.if it were me, I would hang onto the broken radiator and try to repair it as a spare.

 

[Dave Canfield]

Another thing is see if a radiator shop can do a good repair job and then keep it as a backup to guarantee that you never have this problem again.

I don't know what they are hitting you for the new radiator, but I have been surprised sometimes on the cost of custom aluminum radiators. I have seen them for less then some pricey new ones.
