Radiator filler cap

Cheers all.

I currently have a 7 pound radiator filler cap, maybe from Moss by PO.

Seems some fluid escapes, for I see some on top of the radiator after a ride.

My Healey Mechanic tests it and tells me it's a bad cap. Bad as in not making a tight seal.

Here's the problem. Seems my stock radiator neck is a deep style. The cap I have is a deep style cap. Yet it is not making a tight seal.

He gives me a cap that works, but it does not look stock.
He says he can't locate a cap that looks stock.

Any suggestions where I can purchase one?
Read that a stock one should have a brass rivet. That would be nice, but not a deal breaker.

The one my mechanic is letting me borrow, (see attached photo) does not have the two ears on the cap, like original.

Thank you, Roger
 
Try British Car Specialists
 
Roger,

I had one like that and it was bugging me too. I just got a new one from Victoria British and it fits tight and looks pretty good. I ordered some other stuff recently from British Car Specialists (brake parts) and received a package from Moss. I kinda hoped that they would have better stuff, but they're a Moss reseller. When I want to get original parts, I call Healey Surgeons and they seem to have a lot of used old original parts lying around that they're happy to sell.
 
Use the new but not stock looking cap when driving and the older, correct one when showing the car.
 
I got mine from British Car Speicalist and it almost matched the original and works great. Be sure you are not over filling the rad. It does not fill to the top as most others and will stop over flowing when IT is happy with the the level about 1 inch below the lower rim. You may not have enough air to compress. Are you getting "water" from the over flow tube also?
 
Roger, that cap that he let you borrow is not correct. the correct cap has only "2" ears, the rivet is round and smooth . The correct cap is available from "Classics agogo" in the UK, Just specify the depth of the radiator's neck and you will be good to go.---Fwiw---Keoke- /ubbthreads/images/graemlins/yesnod.gif
 
Thank you Keoke. I did mention in my first post, it is not the correct cap.

Good to know were I can order one. Exactly what this post was for. Always count on you Keoke. Cheers, Roger
 
The napa cap also allows a coolant recovery tank to work, as long as one was not concerned with strict originality.
 
Hi Roger,

There was an earlier thread on this and I ended up getting the 1 1/4" cap from Classicsagogo which looks close to original and fits well. Turns out they don't measure the depth of the radiator neck but the overall height of the cap so if you order the 1" cap it will be too short.

Hope this helps.

Cheers,

I was wondering...
Attached is a photo of the cap that has two ears. On the left.

Next to it, the cap that I am presently using, that works.
Notice the cap I am presently using has two rubber seals.

Both caps seem to be the same size.

Is the cap with two ears suppose to have two rubber seals also?

Does the correct 7 pound Healey cap have two rubber seals?

I'm wondering if the other rubber seal keeps the water from excaping the neck?

Reason for this post, is I was finding some anti-freeze on top of my radiator after a drive. (using the two ear cap)

Ciao, Roger

Yes both caps are the same size.

No the cap with two ears is not suppose to have two rubber seals. This cap uses a spring metal seal at the top.

Yes the rubber seal keeps the water from spilling out.

The spring metal seal will also keep the water from spilling out if:

The spring seal is not fatigued or the radiator neck is not damaged on the top of its rim.

No the correct cap does not have two rubber seals.

-------------------------Keoke /ubbthreads/images/graemlins/savewave.gif Cap with two ears is prolly tired,looks tired.- /ubbthreads/images/graemlins/grin.gif

---Wot! Yes if you can find a thin rubber gasket to put on top of the metal spring seal of the two eared cap you may breathe new life into it!--- /ubbthreads/images/graemlins/laugh.gif
 
Yeah SHG,Thats the one. However, I suggest you measure the depth of the neck on your radiator before you order one. This is because the radiator may have been previously repaired and the neck replaced with the shorter US one. This usually occurs when the shop finds it can not meet pressure tests with the defective old original neck.---Keoke
 
Talk about timing! But, I notice it's good only up to '66!? /ubbthreads/images/graemlins/jester.gif
