Radiator

[HellOnWheels]

Just picked up a new radiator for my GN (87). It has the plastic end tanks, hookup for the trans cooler connections, a drain petcock, an overflow pipe connection, and another "nipple" that looks like a 3/8" line would fit!!??

It's application is for an 88 IROC f-body w/a 350 TPI.

Anyone know what the "nipple" connection is for??

TIA
HOW

I just did that conversion in my car last weekend. Mine had some sort of plug in the middle inbetween the two tranny cooler lines. Mine already had a plug in it. I read on another post... some of the f-body radiators have the plug already.... some don't...... but if it doesn't have the plug..... it will leak out the hole.... gotta get a plug for it.....

Just looked at mine

mine has the plastic plug in it. I guess u should tell the place where u got it from to get another one so u dont have to worry about it. What did u pay for the rad anyway?

I think mine was around $117 + tax or so from Autozone. I told them it was for a '92 Z28 with a 350. When they pulled it up on the computer.... it was the same part number as some of the threads on here said to get....... so I bought it..... 1-3/8 flue ..... the one I got 1 day earlier..... had 1-1/8" flue..... I took it back....... installed the Autozone one..... which came with the plug.......

That nipple is for the heater outlet hose on a F-body. They make plugs that fit over it and are held on with a worm clamp. Watch out! I've blown those plugs out. One was from a bad radiator cap and another time from heat and old age. I'd like to find an end tank with out that nipple so that problem is eliminated.

What are you guys doing with the oil cooler lines?

I don't use the oil cooler lines. Haven't used them in last 8-10 year.

I plan on adding an oil cooler I bought the other day...... but temporarily.... I have run the hose out using the stock fittings on the hose closest to the battery... and cut the end off at the other fitting..... I then went to Home Depot and bought a 1/2" male pipe to 3/8 pipe bushing... and screwed straight into the oil filter adaptor.... then put a 3/8 male pipe barb fitting for 3/8 hose on it.... slid the oil cooler line over it and put a hose clamp on it.

I would have just bypassed it all together.... by either removing the pancake adaptor... or just plugging both hoses off with 1/2" pipe plugs.... but was unsure if that would work or not.... so I just left it and ran one hose inbetween the two fittings.....

Oil cooler might get installed this weekend.

I am running full synthetic oil now... so I am not as concerned with high oil temps.....
