Factory five Radiator question

[cfriedman67]

just installed the FF5 radiator after giving up on getting my 1997 cobra style radiator to fit. On the FF5 radiator there are two small threaded outlets on either side of the radiator. What are they for and what gets attached to them?

Thank you

They should have come with petcocks. One is a drain one is an air release

I only received a radiator. i did not buy the complete radiator cooling system from F5. I guess i will need to purchase those.

[michael everson]

Still think it should have come with them. Every one I have installed, they were already in place.

Even with just the radiator, it should have come with petcocks. Give FFR a call and I'll bet they'll have them in the mail tomorrow.

I purchased their radiator & the petcocks came installed...

I just purchased the radiator 2 months ago, and it came with the petcocks installed.... Call them.

Peacocks should have come with it. My first radiator leaked before the car was even running. FFR sent me another but I already had the Breeze upper and lower mounts and shroud installed. These are the things that happen with these projects.

[cfriedman67]

OK. Maybe because I'm a novice and didn't understand what a petcock looked like but now I do. The petcocks are already there. I guess my real question is does anything get hooked up to either the drain or the air release? Also when installing the overflow tank there are two outlets on the bottom. Where do they go to? I just assumed that some how they got connected back to the radiator.

The petcocks don't connect to anything. Open the upper when filling the system to allow air to bleed. Use the lower to drain the system. On the overflow the tube that is open at the bottom goes to the nipple below the cap on the "T" filler and the one connected to the standpipe vents to atmosphere.

Thanks everyone for the help! Simple things are not so simple when you don't know.

Just a small hijack here, but on the same subject. I purchased 1/4" hose to connect the bottom of the overflow to the nipple below the cap on the T filler. Hose fits snug on the overflow, but way too small for the T nipple. I think it's too small to muscle that thing on the T nipple.

I originally used the FFR provided overflow tank but it didn't have enough capacity. Totally drained out when engine was cooled off and I filled it to max when engine was warmed up. I know a lot of people say it's not an issue but I wound up buying a different one from canton racing. Nice thing about this tank is it has a sight tube. Plenty of capacity too. Dadofthree- try 1/4 inch heater hose. It's thicker than regular 1/4 tubing normally used for overflow and it will stretch enough for the tee. A little oil helps here.

If the heater hose is still too tight, try boiling the first couple of inches in a pot on the stove to soften it up.

Just checked my build. I used 5/16 heater hose not 1/4. Sorry about that.

[DadofThree]

To connect the overflow nipple to the fill cap nipple, i put a 3/8 internal compression fitting internal sleeve into the 1/8" hose. Then slid the 1/8" hose inside the 3/8" hose and held with a clamp. Then put the heat gun to the 3/8" and muscled it into the nipple at the fill cap. Worked well (even upside down)

A quick trip to True Value for a barbed hose adapter and 2 clamps...DONE!

I put two layers of electrical heat shrink tubing on the smaller nipple. I heated the first layer to shrink it, added a layer and heated again.
Those two layers made the small nipple the right size for the bigger hose all the way, No extra fittings or clamps and an invisible fix.

I did look for that sucker last week, but couldn't find it. I had the compression fitting parts laying around from your Kleiner mod (for fuel line) that I did on my power steering return line.
