radiator hoses
when I designed our radiator hoses I spent months trying every configuration on different engines and worked out a bottom hose that would fit everything. The old basic shape was wrong and Rover must have realised this when the got to the 1990 models as they redesigned the lower curve plus adding all the outlets. The difference on top hoses is because the thermostat elbow points out at a different position on 998c to 1275cc. I do not think anybody makes a 998cc type top hose in silicon as very few people have ever requested them and tooling is expensive. People with highly tuned 998 often use a 1275 head are therefore able to use the 1275 silicon top hose.

I can't imagine it'd be difficult? Perhaps tie a long piece of string around the old one as you pull it through and then tie that around the new one, so passing it through the bulkhead is easy?

naff radiator hoses
Hi, i was wondering about other peoples views on the kevlar hoses sold by minispares as mine (grh240kevlar/grh245) have both perished badly after a little over two years. The bottom hose burst as i was fiddling with the carb, good for my engine but bad for the top of my arm.I am using ancient hoses i found in the shed at the moment, ironic as they are in very good condition.I did email minispares asking if there could have been a bad batch but i recieved no reply.I don't wont to use blue hoses as they look out of place on a 37 year old mini.

samco do a range of matt black silicone hoses that look like the originals but will last ages if not forever.

Bottom Radiator Hose Sub-Branches
Someone out there, please help me with this. I have a Rover Mini 93 SPI. Where do the sub-branches of the bottom radiator hose lead? The bottom radiator hose and thermostat housing sub-hoses - where do these lead, as well?
What I already have connected:
1) The bottom radiator hose - 1 branch connected to the heater, and another to the lower manifold pipe.
2) Thermostat housing sandwich - 1 branch connected to the heater switch, and another (which is branching out from the first branch) to the upper manifold pipe.
Please correct me if I'm wrong by letting me know the correct pattern.
The reason I'm curious about this pattern is because I had to pull out the head and all the hoses. After the work was done, when the cold engine starts, the rpm is between 1100 to 1300. When the engine reaches a normal temperature, the rpm is jumping from 1400 to almost 2000, and stays there without going down.
Your help would be greatly appreciated.

No Heat ?!?!?
I installed my new heater valve today, but couldnt get any heat whatsoever from the heater. I drained the block, installed the valve, re-filled the system and fired it up without the radiator cap fitted. The thermostat is an 88C unit, and the temp rose to about 88-90 (ish), but the heater hoses remained stone cold - regardless of the positioning of the heater cable. So, thinking that there could be a blockage somewhere in the system, I let things cool down a bit, disconnected the heater hose from the lower radiator hose and blew into it, watching for displaced coolant flow from the lower radiator hose takeoff. While blowing, I operated the valve by hand to ensure that it was functioning. Since I witnessed coolant flow from the lower radiator hose takeoff, so can I safely assume that the overall cooling system is clear of any blockages? Why, then, isnt there any heat? Im searching through the boxes of bits tomorrow for another thermostat, just in case, but this is puzzling me.

re brakes
Sorry I should have been a bit more specific, I meant a radiator hose not a brake hose and on closer inspection it was the radiator that had gone. I've managed to get hold of a new master cylinder so I'll give that a go and if that doesn't work I might have to do the compensator valve. If I still have no joy I think I'll buy a push bike!

Coolant leak
After a few days of being parked in my garage I seem to always find a small puddle of coolant on the floor from my 1981 mini 1000. I've changed the radiator, top and bottom hoses and jubilee clips. I've also had a new water pump fitted. I've check the level in the radiator and that seems fine as it is at the top. The puddle also seem to be more under the middle of the engine. I thought it could be the By-pass hose? Is there anywhere else this leak could be coming from? Any help with be appreciated! thanks.

cold heater
Mine was also blowing cold air - found out my lower radiator hose was also cold and the temperature gauge was glowing red - I just ordered a new radiator.

At a rough guess I would say that the heater is airlocked, try discounting the heater return hose at the joint to the bottom radiator hose and then run the engine with the heater valve open. When coolant starts to flow out of the pipe from the heater unit switch off and reconnect.

parts
if your radiator has a hole, then all you need is a new radiator, the hoses should be fine, although if the clips are old they might be worth changing. minispares do the mk3 cooper grille which is chrome and looks really good. they do rocker covers too, and an alloy one would look best

over heat
flush your rad through to get rid of the crap in it. Take it out and run a hose through it for about 10 mins. I warn you though that the bottom radiator hose is possibly the gayest (is that a word?) bastard of a hose to get off

re
Did the problem come on suddenly or after a rebuild etc? Maybe your radiator is blocked up and corroded beyond flushing. Take the bottom hose off and check the water is really flowing through clearly. It may be that something is lodged in a hose or in the water passages of the engine.

Temp gauge reading high
Same issues on hot weather ... => than 35/36 °C outside temperature. Smiths seems over reading the temp. No water leaks new radiator new hoses no coolant low level apparently no troubles at all in the cooling system (SPI) ACR4 says when the needle is over the N position that engine temp is around 90-92 °C (thermostat is a 74 °C type).

right lads its back over heating again this time think iv sussed it ... the systom had lots of water and only serton pipes where hot to touch and the radiator was only luke warm and the pressure in there was unreal .... couldnt even squeese the pipes at one point when iv let it cool and got the pressure out went round and had a look at some of the pipes and one of them was filled full with somthink felt like slushy like had a crunch consistancy after squeesing it for a fue mins i topped water levels back up and started it ran perfect for about 50 mins then ... over heated again ... now the slushy ness is near my heater in the car and its no where else and 3 quaters of the pipes are hot again ... so im thinking blockage somewhere ? im thinking old crappy anti freeze ..... so im on the hunt for a hose kit of my car only one i can find is this one and to me it doesnt look right so can one of you guys take a look at it and just tell me it is or if it isnt basicly iv already flushed the systom when i did the water pump and thermostat just hope its not in my radiator
i got told to flush the systom fully back and forth all pipes radiator heater the works so i did
right for all use that are intrested in this thread and not sick of me and a fue mates on sunday after getting over missing the run out we got stuck into the mini taking off every pipe i could with out removing to much and making a big job and disconected every pipe and stuck the hose pipe down every hole every pipe and ran it till it was cristle clear as i was doing this there was tiny bits of metal flakes looked like rust flakes but not 100% so everythink was clean water put pipes back on filled up water again ran it through check all pipes all were hot turned it off let it settle and toped up levels ... then took it for a run down the sea frount out for around 40-50 mins before the beer and bbq was calling with the lads obv... as the weather was loverly ... car ran loverly never over heated never built up pressure nothink today was scorching weather again run to work was around 40 mins again and nothink got a little hot but then pulled it self back down tomorrow im going to try and take it for a long run out see what happends ... anyone else have anythink i can check or do to elimanate another problem it could be or could have been may be the case ?

Steaming Mini
Dificult to say really. Could be a main hose, radiator or water pump. If there isn't anything obvious when refilling the radiator then suspect the small bypass hose between the water pump and the head. They're a weak spot allegedly.
It was a horrible morning though to be having to look under the bonnet - I know because my son dragged me out of bed to do just that when he wanted to drive to college and he flooded the carb. Yeh, I know you don't really need to open the lid but I wanted to check the fuel level in the filter chamber to be on the safe side.
