Just wondering if any OPPOs have successfully patched a radiator leak and if so, what you used. The $600 geo has a conviniently located leak right on top of the radiator and while I could get a new one for like $60 I kinda want to try patching it first as (A) money is extremely tight right now and (B) the point of the car was the absolute cheapest DD possible.

Pictured: what I wish it looked like.

True story: my Tercel had a crack in the radiator right at the lip where the cap tightens. Was a nightmare for a while. Then one day on a whim, I swapped caps between it and my pickup (which was old OEM and fit better). Never leaked again. I tried soldering it twice and failed miserably...

TL;DR I miss my Tercel

PS - Your car is ruined. I’ll take it off your hands.

I think usually to really repair them you would have to braze/solder the hole. I’ve never done it personally but I’m willing to bet there are tutorials on YouTube.

Ive put a smooth fitting into a threaded port, I used jb weld or an off-brand equivilent(I dont remember). It was doing 100% of the water sealing because the fitting was basically jammed into a threaded port of similar size. Drove it like that for a month with no issue, then I replaced it.

I patched a small leak in the fins on an SBC 350 with JB Weld. Put a bunch in the crack with a toothpick and let it sit for at least a day.

As much as I hate it, Bars stop leak does work pretty damn well.

JB Weld and other epoxy stuff is a very temporary fix. It will work but keep a spare kit with you just in case.

Im guessing a junk yard is out of the question? Those were basically Corollas. You may get lucky in the $15-$25 range.

How bad is the leak? Distilled water is pretty cheap. True story, I drove my MJ for five months going through about a gallon per hour. Once the level dropped far enough it stopped leaking, too... but it did also get kinda hot at times. Hey, nearly free hot flush, though...

When you say it has a leak at the top, is it in the fins or is it in the very top. I had an Isuzu which had a fiberglass-reinforced nylon top, and nothing would fix that once it cracked.

If you want to try driving it without coolant pressure, sometimes just leaving the cap loose is a good temporary solution for the time being if the car lets you get away with it.

Came here to say “Yep, I used a replacement radiator.” But then I read the post, so JB Weld.

Jb weld will work if you clean the surface and let it sit for 24 hours. Acid core solder is applied with a torch, also effective. If the plastic is cracked try melting a zip tie into the crack with a soldering iron
