Cheap dual core radiator $87

My spectra 951 radiator developed a leak so I ordered a new OSC 951 radiator for $87 from Rock Auto and to my surprise it was a 1/4" thicker and two core. No issues getting it in and seems to be cooling great. Thought I would share

Interesting.... I just ordered the GPD 951C as it is called out as "2 Row Core"
When it comes in next week I will have to measure it.

Re: Cheap dual core radiator $87

It says 2 row "equivalent". That's not the same as actually having 2 rows, but if it's cooling well, that's all that really matters...

I got a new radiator for my Toyota 4Runner from Rock Auto last year and am quite pleased with it...

Re: Cheap dual core radiator $87

Man.

Rock Auto had this one fast tracked to us.

Ordered on Monday and have it in hand Wednesday.





It looks like two 5/8" flat tubes side by side in there.

I can snag my finger nail on the center section of the tubes.

If you squint and turn your monitor too 43 degrees you can imagine that you are seeing a seem that I describe above...





I spy the trans cooler section in there.





Hopefully this will help keep the temperatures in check.

After the system is cleaned with the proper coolant system flush.
