Voyager/Caravan radiator leak

Jan 26, 2004 4 Replies
1992 Voyager. On its third radiator. The first lasted 140,000 miles. The second was defective as installed. The third was a warranty repair for the second and has lasted just a year.

Leak is the same place each time, top right side rear ( by the hose, facing engine) at the crimped joint. This seems like a design flaw.



If I crimp the joint a little tighter can I make it last longer?

Oh geeze, how could it be a design flaw if the original rad lasted 140000 miles?

Sounds to me like you have a bad rad cap. That joint just happens to normally be the hottest and highest pressure area in the cooling system since the hot water from the engine goes into the rad there. So if the system is overpressure it will burst there. Did you change the rad cap or are you still running the original?

Well, yes, actually. The engine mounts have been bad for months. When I replace them it will be the fourth set since I've owned it (90,000 miles). Any idea why they go bad so often?

The cap was replaced with the last radiator, about one year ago and perhaps

8,000 miles. Could it leak from the cap but leave no wet areas above the crimp joint? There is lots of green at and below that joint but none above.

You're probably right that a flawed design would never have lasted that long. I think the engine mounts may be the cause- see my other post. I have let them go because I am tired of replacing them so frequently.
