sandwich plate
Hey all,
quick query, when a sandwich plate is fitted on a 1275 engine, should the thermostat be fitted in the head as normal, or sat in the top of the sandwich plate. As they both have the same recessed hole for the thermostat, just wondering, not sure if it makes a difference as is the heater take off.

Good afernoon,
The thermostat should be sat ontop of the sandwich plate. Not too sure on the exact reason for this however.
Regards

engine steady
Hi all, just another quick one, i bought a ultimate engine steady for my 1990 cooper, and im having a little trouble, the sandwich plate with heater hose take-off is right in the way, does anyone know if it is ok to rotate the sandwich plate and route the heater pipe around the engine bay, I have the cirrect engine steady but there is no hole for the pipe to pass through, Cheers Nick

manifold
Had the same problem with mine. I took me ages to work out how it fitted. Mine fits flat onto the cylinder head and over the first stud on the exaust manifold. I cut this corner off on mine because it means if you want to replace the exhaust gasket, you have to replace all the sandwich plate gaskets too.

HELP! engine steady won't fit!!
Are you sure you have the correct type of ultimate engine steady for your model, because I needed the injection type (part "EL59") for my 90' Mainstream (Carb) Mini Cooper due to the thermostat sandwich plate.

Hi Nick, The engine steady plate sits on the cylinder head, ie right at the bottom of the sandwich plates. This allows the the heater pipe to maintain the correct route. Dont forget to put a gasket between all the joints!!! Simon

steady
Hi, ive checked this and the steady doesnt clear the exhaust manifold, for some reason it seems as if it should sit above the sandwich plate, Cheers Nick

steady checking!!
Just been out in the rain to double check mine, you got me thinking!!! Right, the steady deff fits under sandwich plate. At the back of the plate there should be 2 holes. One for the threaded steady bar to go through and the other one is for the outside exhaust manifold stud to go through. You have to take this out when fitting. You will probably also have to put some small washers or similar on the stud, between the manifold and steady as spacers when refitting, as i had to. Hope this helps. All this is assuming you have the same ultimate enginge steady as me!!!! Simon

In terms of even cooling of the engine its best to drill out the 1275 head to take heater take off there. The sandwich plate may have a hole drilled in it for a vacuum switch thermostat but anything that will block hole will do.

Coolio
On mine l plumbed the heater take off into a new sandwich plate (stocked by MS or Moss) with a 12mm inlet, which sits under the existing housing on the c/head. l would also replace the fan with an electric unit. A high pressure rad cap is also worth fitting.

Head Steady + Radiator Bracket.
I have a standard 1983 998 + stage 1 kit but have fitted a sandwich plate inbetween the thermostat housing and cylider head.
Any thought on which utlimate engine steady I should looking to get?
From what I gather the cooper 1275 1990 - 1992 carb that uses the sandwich plate is wrong because they use a large bore thermostat, so I was thinking the single point injection one but I don't understand what the differrence between the 1275 and the 998 head steady is. Prehaps the 1275's sit higher.
I also need to think about which rad bracket to buy. Same problem. Any thoughts?
Thanks.

Thermostat Housing/Plate on '92 1275
Hi, I ‘m after some advice on parts for the cooling system on my K-Reg (1992) British Open Classic. I know that I have a thermostat housing with a sandwich plate, but I’m unsure which of the components in the minispares catalogue are suitable replacements. The ones I’ve looked at either specify older models without plates, or cooper models. Can anyone help? Regards, Dave.

Heater hoses
Anyone else correct me if i'm wrong, but in a metro there is no bypass in the head (either not drilled out or has a blank plate on it), and the water pump has no bypass.
I think the alternative route for the heater pipe circuit on a metro, rather than the bypass take offs mentioned above, is from a take off on a sandwich plate between the thermostat housing and the cylinder head, runs through the heater, then back through a take off in the pipe that runs from the water pump to the radiator bottom hose.

It all helps, but using water wetter made the biggest difference.

the strange thing is
you could purchase an mpi housing, if the thread is the same, else the 1990 coopers had a sandwich plate on the thermostat housing that was used for the aux fan, you could try that, but again, it may have a different thread
or the final one, get the original hole drilled and tapped out in the head.

This is the one I've got on my 1990 Mini Cooper (carb model), but mine also has the sandwich plate with the auxilliary electric cooling fan thermostat attachment.

But my temperature gauge sender terminal is in the standard position just below this.

Removal of factory electric fan
Hi. I have a 1993 mini 1275 and after having rad issues I see that in the front wing is a yellow electric fan as well as the 10 blade plastic one on the engine. I was going to replace the engine fan with a couple of single metal blades for more air flow. Can I just remove the old inner wing fan and leave a gaping hole in the wing or will it increase my chances of putting a stone through the rad too much?
Also I have a question about the water temp sensors. I know the vacuum one on the sandwich plate is for the charcoal canister and can be done away with. Is the one in the head for the temp in the dash and the one in the bottom of the rad for the electric fan?
Any info on this would be greatly aappreciated

Cylinder head without bypass
Hi all
I have acquired an unleaded head for my 1979 mini. I presume the head is from a metro as there is no bypass. Can I buy a sandwich plate and run some hose from it to the bypass on the water pump? Would this work? If yes then a yes is all I need and if not can you tell me why this wouldn't work. I have asked this question on other mini forums and not gotten a straight answer. It very frustrating. I know my other options are to do away with bypass altogether and drill holes in the thermostat or get a genuine mini head converted to unleaded or just use a lead additive.
Thanks in advance

I think its the right one, it came from ebay so im not sure. Its bacsically a big shroud of metal the fits ontop of the thermostat housing, it doesn't have a sandwich plate. the trouble the hole where the rod goes through is directly infron of the top of the breather. Plus i think it will rub slightly on my heater take off pipe. I may hjave to modify the bracket a bit.
My main problem was whether I can transfer the pipe from the carb to going onto the rocker cover take off, rather than from the breather from the tappet chest cover.
thanks,
James
