Repair Coolant Resevoir with Epoxy?


Recommended Posts

If you mean a hairline crack I don't see why it wouldn't work as a cheap "fix".

However, if the plastic is quite old, chances are the fix might only be temporary. The crack could grow or more could appear in a short amount of time.

Not to mention you would have to probably first remove the tank and then pressurize or create sufficient vacuum in the reservoir to locate the leak(s).

All that time and effort...

All to save a few hundred dollars on a new reservoir?

Or am I missing something obvious here.

Definitely a temp fix. I have a DE this weekend and thought I could get it done tomorrow before I leave Friday. It started at Mid-Ohio a couple of months back and I should have replaced the tank between then and now. Been busy with kids, work, life, etc. So, do I just leave it for the weekend or play with some JB Weld or 2 part epoxy?

We have never seen this type of repair last either. You also need to consider where the tank is cracked; sometimes it is necessary to remove the tank to see or attempt to repair the crack, making a temporary repair a little ridiculous..........
