It employs a round heater. The plate says it is a SMITHS model R200. Code: FHR 2404. I've heard such items are obsolete. They do tend to keep the passenger's knees warm! Probably made by the fine people who made the equally functional gauges! Seriously, I've read that a round heater from the back of old Volvo wagons can fit & work better. Other than that, know little about such heaters & liitle info is found in any of the books I have. I may need a core in the future. -Fred Kuzyk Morgan Sports car Club Canada --------------------------------------------------- Date: 03-Sep-1997 11:40:04 From: Subject: Re: [Fwd: Re: Heater] My 1972 4/4 has this heater, and when it developed a leak a couple of years back, I mentioned it a friend round the pub who said the Morris Minor used the same heater, and he just happenned to have half a dozen a them in a field! It cost me two pints, and it was a little deeper than the one previously fitted, but is still doing a great job to this day.

Works really well and can't even be seen. Cheap too. CB -------------------------------------------------- Speaking of J. C. Whitney, I bought a pretty nice hot water heater from them for my Morgan. Measures 7" x 7" x 7", two speed blower for about 119.00 less your preferred customer discount of course. Will bolt right through the firewall or weld some bolts to the case (after taking the core out) and run some hoses to coincide with the old Smith's holes. Actually puts out some heat and doesn't leak. You can take the doors off the Smith's, make some little brackets and attach it to the new heater, no one will know the difference, but they'll wonder why it's so warm! ------------------------------------------------- Excellent comments.I second them . Before adding an oil cooler, it is best to know exactly what temp your oil is running. The best temps for petroleum based oil are in the 180 to 210 degrees F. Cooler that that causes excessive engine wear due to sudge and acid formation, hotter causes the oil to break down and oxidize. Either one is very bad.

Anyway he got his from Griffin Radiator; 100 Hurricane Creek Road; Piedmont, SC. 1-800-722-3723.
