After adding a gallon of antifreeze I found it on the floor. The source of the leak is a "hole" on the back, right side of the radiator. It is a threaded hole and it looks like the place for the thermoswitch on the opposite side. My question is what goes there? It obviously fell out of my car. The exact place is: as you are looking from the front of the car, at the back of the radiator,driver side; two holes top and bottom.

 

That's where the oil cooler connections would be if it were installed.

 

Thanks, if the oil cooler is not present shouldn't their be a plug of some sort in the holes?

 

Hi Mike,

I have heard of a tapered quick release plug that can replace an oil drain plug. You pull the handle to seal or remove the plug. It could have been from Pep Boys. That could help temporarilly.

Is what you are talking about anything like this? Can it be used in place of the radiator drain plug in addition to using one for the oil drain plug?

the direct product link does'nt work for some reason, so to view what I was trying to link, go to performanceproducts.com --&gt;then enter your YEAR--&gt; MAKE--&gt; and MODEL--&gt;finally go to ENGINE--&gt;ENGINE LUBRICATION--&gt; and finally you will be at OIL DRAIN VALVE.

Pilotshark,

Good info.

When on the page with the drain valve, assuming you have internet explorer, right click and select "open frame in new window". then cut and paste the address from the new window. I couldn't get the "URL" tag to work, so I just pasted the link in my message. Looks wierd, but it makes a good link.

Thanks Greg, btw what is the verdict? would this work? I believe the drain plug for the oil is the same size (diameter) as the radiator plug. If it would be a good idea for the oil, wouldn't it be ok to use in my new Devek radiator as well? I would hate to waste any money on a useless shark item when there are so many other items that need replacement. Thanks for the input.

APOLOGIES to Michael G. didn't mean to hijack your thread. <img src="graemlins/yltype.gif" border="0" alt="[typing]" />

 

If it were me, I would consider a solid plug as a temporary radiator fix. The quick drain plug may not hold the radiator pressure as well as a solid plug. I don't see pressure spec. on the quick drain plug. Could it release unser radiator pressure? I see no benefit to having a quick release for the radiator plug. A simple solid threaded plug is what I would do.

Speakin' of fishin' Greg ...

Perhaps something like this would work as well - usually available at boat supply stores:
