Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Trad Air Condtioning

Thank you Richard. Yes, that is later schematic used for car 8-14 years years later. I was trying to get as closely to the DaveW standard as possible. Sadly,, during the hard times, Morgan would outsource and alter components/suppliers frequently. That is why, for example, the electrical diagrams kept becoming more difficult to read. In this case, the people preparing the all-important Parts books (1999 to 2014 IIRC) . Management developed a less patient and less interactive policy with suppliers.


Not Richard's fault, George. RicharV6 is having the same problem as the dealers and other owners have with the later Part Books for some time. Richard chose a diagram from another newer one. Lovely pictures but you have to be trained in the Parts books creators programming to decipher them. And even then, numbers are not explained unless you are in the possession of OTHER regularly changed pages continuing the explanation of those numbers. Morgan would issue special part#s pages with prices with ever changing price for dealers only. I stopped collecting them many years ago.

However, the Parts department fellas are pretty savvy and deal in the black arts. (wry smile). They wisely dislike changing Parts #s . (TG!) So look at the diagram I posted with the numbers below and merely consult the part #s on my older diagram. That is another reason why I used it. You are right, prettier pictures don't help the community if we don't know the parts they refer to. These few trad parts books and community experience/aptitude are vital to the survival of our cars.

I also have the original electrical diagram for Roadster AC. It was made for the US early on in the wave of early S2 Roadsters that went to the USA before the MMC ran out of airbags. Inserted below for you George..though I am not sure how electrics explain how these models are cooled, with or without AC.


Interesting thoughts Richard. Thank you. We can all cogitate. It would help the Roadster fellows immensely, AQC or not. The other AC cars seem to have the same setup. .

I don't see much change in this area from the first to the second diagram, save the overflow or expansion tank seems to have trebled in size and moved to the right hand side of the engine bay from the left.

Hey! Let's be unambitious at this point. It would be great to improve the AC with a simple fix. However, if we can figure it out the entire cooling system, we can end the heating issues (especially the 3.7s). At this pint one cannot expect any help in this area or other areas from the Works. If we can confirm a fix, I am sure some enterprising young aftermarketeer will produce and sell them. Bless'em. The parts needed are inexpensive.

Which hoses are the target for the bypass are obvious...the ones going in and out of matrix covered by the climate box. But I cannot confirm anything without a Roadster at hand. I also see other things that could be addressed. For example, (do not shoot me) placing a AC rad in front of a coolant rad, is .....er....."problematic" for a small vintage sports car with a small cowl and an engine bay designed for (originally) 36bhp. Akin to placing an oil cooler under a rad.

P.S. I also see other things that could be addressed. For example, (do not shoot me) placing a AC rad in front of a coolant rad, is .....er....."problematic" for a small vintage sports car with a tiny cowl and a very small engine bay. Akin to placing an oil cooler under a rad or a pretty engine cover that has to block airflow around the engine and inhibit access. Much wiser to polish and chrome the engine like I did!



Sorry, best diagram quality I have.
