Radiator Repair

[Shak14]

Has anyone used any type of radiator stop-leak for small radiator leaks? I seem to have a slow leak, but wondering if it’s worth a shot to try a band-aid versus a complete replacement. Any advice is appreciated.

The leak stop stuff is a temporary repair, don't leave it in long term. Plus, you need to make sure where your loss is at. Is it a visible leak from the radiator, hose, plastic fitting, etc or is it really a head gasket, EGR failure, etc?

Don't use stop leak, the system is made for liquid and goes all through your block.

You can have the radiator repaired normally, but not sure if it's cheaper than just replacing.

Have you pressure tested to find it yet?

go to auto zone get the free to you with a deposit radiator pressure test for leak down. See where it is leaking. Can't see? Thats bad, check plugs, intake, etc.

I can see the leak. Looks like most others that have posted before me. It is on the drivers side of the radiator. Slow drip.

Went ahead and ordered a new radiator and will do a little DIY in the driveway. Anyone have a good write up for swapping radiators?

If you do a little digging there is a complete radiator replacement procedure posted here somewhere. It’s pretty common, takes about an hour with common tools. Definitely don’t use stop leak. Your heater core will thank you.

Finally got the radiator delivered today and got it swapped. Right around a 2 hour driveway job. All seems good so far.

Yep, super easy. A great money maker for the shop.

I think the best price I got to do the job was $900. I’ll stick with the $200 I spent for the radiator, coolant and a little bit of time.
