My surveyor recommended changing the pressure caps on the heat exchanger's on my Perkins 4.154M diesels. Does anyone know where I could obtain these?
Thanks,
Bill
 
the pressure rating is usually stamped on them
 
I'll take a closer look next time I visit the boat. They aren't leaking but the seals look dusted so I don't want a problem.

My caps are 13 lbs I picked them up at the auto parts store.
 
I think they might be 7# caps. That's what's on a many of the old Perks. Probably not too hard to find, but if all else fails, Transatlantic Diesel has them.

Thanks I have an e-mail into TAD late this afternoon. I have found them to be very responsive. They carry almost anything I would need to service or rebuild these motors. A rebuild or re[placement is not in my current plans. I believe the motors properly run have at least 10,000 hours of life left in them. I'll keep the fuel clean, and change the oil and filters as recommended by Perkins/ Mazda used this motor in pickup trucks in Australia, (Not the marinized version).

Get the pressure spec and go to a NAPA store. Not everything has to be priced like jewelry
 
Bill,

I assume your heat exchangers have coolant recovery bottles attached to the overflows on the head exchanger fills. If they do, there is a difference in the design of the caps and you need to specify coolant recovery when you buy them. It's not a problem, they are very common.

By the way, the two MOT GMRS radios you sent to us a couple of years ago are working fine and are used for bridge-to-cabin comms on every cruise. It's the only radio that the Admiral is truly comfortable with.

Good luck with your GulfStar. I have always admired them. I make sure I read all of your posts.

Hello Bill my fellow ham operator (I'm AA2UK) in the ham world. Which reminds me I need to renew my license soon. There are no coolant recover bottles on the heat exchangers. Now I'm thinking I need to figure out a way to add them One thing I m not good at is mechanical engine related stuff. Converting analog to NMEA2000 on old school diesels I can do in my sleep. As far as anything other than adding fluids or checking levels is where my comfort level stops.
I'm glad the FRS/GMRS handhelds work for you we have about 10 systems in boats at our marina. One guy even does a morning show at 7AM on channel 1!
Thanks,
Bill
 
TAD Inc just called these pressure caps are rated for 7 lbs and these motors do not come with recovery tanks in the marinized version. They told me any cap from NAPA that is under 10 lbs will work fine.
