Radiator repair

[Industrial Toys]

Our equiv of harbour freight offers a chinesium plastic welder, cheap (for what they usually cost) but still rather expensive. What makes them so expensive? Not like they use high frequency or anything fancy like industrial stuff.

Do you have the broken piece?

I would drill a bunch of holes and put some stainless 6-32 machine screws around the hole facing up with nuts. Roughen and clean the area and use the best adhesive you think might stick to the plastic and can take the heat. Not sure if that Lepages PL 25 (?) would stick to that plastic, but it's a crazy strong adhesive. Also not sure if it handles any temperature.

Go with a competent radiator repair shop.

They may even have a line of replacement radiators available that are less money than OEM.

I just sent my motorcycle radiator to a well known motorcycle radiator repair shop. I'll probably have $100 or so in it. OEM was $800 for new. I just can't risk being somewhere out in the boondocks and have a DIY goop radiator repair fail.

Our local rad shop clsed up after many years. Too many aluminum and plastic rads out there now.

I took my leaking generator rad to another guy an hour away. Said he would repair it no problem, cheaply. Got it back and all he did was cut out the bad part! I could have done that myself and saved the money and time.

this would be my route, go after market rather than cobbling a patch, you can't afford even 1 overheating incident

That is not fixable...

One day I guy I know with a Landcruiser similar to mine asked if I wanted his old radiator. He said he just got a new aluminum one. I knew the old one was brass and copper. So I took it.

Took it into the radiator shop and they rerodded it and took off the tanks and rebrazed them. Good as new.

A year later he blew that aluminum radiator. He also said it never could cool the motor. Turns out it was a single core " high efficiency radiator". Well, the coolant never stayed in the radiator long enough to take any heat out of the coolant. Beware of high efficiency radiators when getting a new one.

And watch it flow out of the hole faster than it can be poured in! An plug up the small ports throughout the system. Leave the corn meal in the kitchen for cornbread or coating food to fry!

you guys actually took the bait, seriously....

back to the OP: Snobdds' comment about finding a multi core aftermarket radiator is an excellent point. personally would be looking at biting the bullet & going OEM. wouldn't dream of cobbling a patch. that's about as reliable as using cornmeal.
good luck, best regards
