Coolant Leak

Last Friday I smelled coolant while driving driving back from doing my license renewal.
When I got home and looked for the leak, I found this beautiful piece of planned obsolescence.
Automotive tire Automotive fuel system Motor vehicle Suspension Automotive exhaust

I searched on the forums here and found that Dorman hade made a greatly improved setup, using aluminum instead of plastic..
The "spring" pliers that I "sprang" for at NAPA, cost more than the hose set-up!
The hoses were all pretty much easy to reach, and the lock on the spring pliers made it super easy to slip the clamps off & on.
I refilled the rad and added a little extra to the overflow bottle, for good measure. 馃槑

That's why they make metal ones. Hope that's what you replaced them with.

Sorry for the technical oversight Sienile, it seems that I had 2 browsers running as I was posting here and shopping for my little red rocket some parts.

How many miles does your van have? Curious to know how long these plastic parts last.
Mine just rolled 120k...

120k is about the mileage the oil coolers like to fail at. They have all metal versions of those too. Might want to get you one on order for when yours springs a leak, or do it before then.

Thanks for the heads up!
I knew the oil cooler was plastic too, but didn't know it's failure was any kind of predictable.

From what I have learned on this forum there seems to be two modes of failure for the oil cooler. First is a multiple answer, leaks caused by enthusiastic techs tightening the oil filter cap way too much or competent people tightening it correctly and the plastic just getting fatigued. Second is the seals getting old and brittle and start to leak. Third is the plastic just gets stresses from heat and pressure and begins to leak.

A member noted that he could not find any failure of the OEM cooler but it was leaking, hence the above notationHowever he did replace the oil cooler with one of the aluminum ones. I don鈥檛 think anyone wants to try the OEM cooler and just replace the seals, I know that if I pull mine off it will get replaced regardless of what is causing the leak.

Dorman also makes some aluminum cooling system parts.
