Need a Radiator cap part I can use for a Modine S3 replacement Radiator model 433084 from O'Reilly.

Anyone with this radiator and if so can you give me the cap part? The manual does not even list the cap part and the stock cap is bigger by about 1/8 of an inch.

Local parts store should be able to tell you what one cant they?

 

Yea I guess i'll take the whole thing with me tomorrow. I know a few other people do have this radiator. Saw pics the other day forget who it was. And the product website is useless. Who makes a radiator and puts a manual in the box with nothing about the cap? (insert random curse words).

 

apparently modine does

 

It looks like the 86-91 cap might fit.

 

Follow up: Found out it's a Stant 7037 Cap. In case anyone buys this.

I called Modine and they didn't even know or want to bother to look it up.

 

That is what most of us on the forum call the tall style 1st gen radiator. Stock tall style rads typically had the larger cap while aftermarket ones, like yours, tend to have the smaller cap.

 

OMG this blowz. I got the 7037 and it's too small. The quest continues. I don't want to pull it out but I guess I have to drag the whole thing back to the store.

 

Won't a stock rad cap work? Seems to me if its a reputable company that built it that it should use the same cap as stock.

 

Yea I called Modine and they guys says "we just sell radiators". I said yea.. and what cap does it need?.. "I don't know you'll have to call the people that buy them from us".

Here is a pic

 

Looks no different from the small cap tall rads I have.

 

Do you remember a part number for the cap?

 

Ok I do apolgize for the length of this thread. But so that I don't leave anything
unfinished in case anyone buys one of these since several parts stores stock Modines. I took the radiator to Auto Zone and the mgr helped me find the cap!

It's a CST (generic brand) 7516.
