im going to be getting a Be Cool custom fit aluminum radiator for my 93 z, its crossflow, and also has a transmission cooler hook up on it since my trans has a cooler on it already, does anyone have any info on the original radior that were in the early LT1s ?

 

The stock radiators were aluminum crossflow types with transmission cooler, if auto, and some had engine oil cooler connections if the performance option was ordered. They worked fine unless they got clogged. You need a radiator with a built in transmission oil cooler to keep the transmission happy. The external transmission coolers are considered auxiliary coolers and you still need the inernal cooler. Unless you plan to make some major mods, you can save a quite few bux by just using a new stock radiator.

 

it says it has a transmission cooler, doesnt say anything about an engine oil cooler, i know my trans has the internal cooler, i dont have the external cooler

this is the one i was looking at getting http://store.summitracing.com/partde...p;autoview=sku

it says it can lower the operating temperatue thats why i wanted to get it, and the radiator i have now is getting pretty old need to be replaced soon

 

It will lower the temp if the thermostat and fans setting allow it, otherwise it will hold the same temp. Check if your car has an oil cooler. The cooler is mounted between the block and oil filter and has coolant lines going to the radiator.

 

ok i will check it out tomarrow and get back to you

 

i see a line going to the radiator from the oil pump so maybe it does have an oil cooler ?

 

There should be two hoses/pipes going from the oil cooler to the radiator. The oil cooler is sandwiched between the engine block and the oil filter. The oil pump is internal to the engine and not visible.
