any clues would be great
for some reason i keep blowing bottom hoses.i replaced my water pump with one with a larger impleller and the new bottom hose lasted about 400 miles and split
just past the jubillee clip on the water pump neck.i replaced it and just assumed it was defective and this next one has lasted 75 miles and has a slight spilt and
losing coolant.i drive spirited but not racing so iam going to get a set of silicone hoses but does anyone have any idea why this could be happening?there doesn't seen to be any rough edges on pump outlet - any advice really appreciated as always tony c

I think you must have just been really unlucky with two faulty hoses - take them back!

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.

Easy job, if not a bit fiddly. I assume its the top and bottom radiater hoses and heater hoses, probably not sold as a complete kit, but I could be wrong. start off with the rad hoses and replacing is very straight forward. the heater hoses inside the car will still hold some water so get a container to catch it in. Disconect both ends of the heater hoses from under the bonnet, one is on the heater tap on the lefthand side as you look at it, the other is attached to the rad bottom hose, which you will have allready detached. Probably have to remove the heater to make life easier detach hoses and pull through the bulk head, and may well be best to check the heater matrix while its out. Water pump bypass hose will require the radiator to be removed. Remove the top bracket and then lose your temper removing the two bolts securing the bottom bracket, do this while you replace the bottom hose as it will be much easier. Then remove the fan thats been getting in your way of removing the bottom bolts and on the bottom of the pump is a small flex hose Various amounts of spanner rash will be acquired and patience lost with the rad removal/bottom hose. http://www.minispares.com/Product.aspx?pid=34509 http://www.minispares.com/Product.aspx?pid=34757 http://www.minispares.com/Product.aspx?pid=36718 http://www.minispares.com/Product.aspx?pid=37502 http://www.minispares.com/Product.aspx?pid=38050 http://www.minispares.com/Product.aspx?pid=38550 Hope my poor explanation has helped, Im sure others will add stuff/correct me, but from memory I think thats it haynes never even replied to my job request

heater hose connection
One end to the take-off on the cylinder head (flywheel end) and one end to the T-joint in the bottom hose (below the water pump). Simple.

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.

Which way do the heater hoses go?
I'm fitting a standard heater in my 1987 mini and don't know which is its outlet pipe and which is the inlet. One heater hose comes from the top of the cylinder head and one from the radiator bottom hose, but can someone tell me which one goes into the top pipe on the heater and which on the bottom? Many thanks.

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.

HELP NEEDED
You should be able to see if your pump has a bypass hose or not - it's a straight rubber tube about 3 inches long that links the top of the pump to the bottom of the cylinder head.

Over Heating
u tryied giving your rad a flush with a hose disconnect bottom pipe and flush it through. if ur using a 1275 in a 998 shell and are still using the 998 rad with no auxilary fan then it will be very prone to overheating. if u still have truble cheak the mixture isnt too lean these can happen if uv modifyied the engine eg K&N airfilter. if that isnt the case then minispares uprated 2 core rad is very good and will hopefully cure it.

help - water dripping
Most probably just a leaky hose - it certainly cant be coming from the bottom of the engine. Just have a good look and trace it back. Dont put Radweld in if you can avod it - some people swear by it but in my opinion it just causes blockages and stores up trouble for later.

radiator...
Advice for rad removal... Try to loosen the hose clamp as much as possible. Remove all the bolts and brackets and other hoses and start pulling the rad upwards. You should be able to reach down with your other hand and reach that bottom clamp while pulling. If you still cant loosen it, use a flat screwdriver to try and pry it off. I was able to loosen mine enough to pull it loose. If the hose is in good shape, just put it back on when your done - with a NEW stainless steel hose clamp. If its sketchy looking, now is the perfect time to replace it. If you have to, cut it off. Getting your car cooling properly is important enough to do this right. Taking the radiator to a shop will be FAR more effective than a flush. They will soak it in a caustic bath for a couple of hours and run pressurized cleaner through it. You cant get it nearly as clean with a simple flush. Plus, the top of the rad will be a cool copper color when youre done. Remember, its far more expensive to repair or replace a warped head that a bottom hose... Vince

No Heat ?!?!?
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.

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

hoses
yes you can use the bottom hose but not the top as it is the wrong shape for 998cc but I am going to set about getting a 998 silicon hose made for all 998cc but taht will be some months away. the clubman 998 hose can be used for a minii and cut down but it will only fit a 998 and not 1275. dont get confused as there was 998 and 1275 clubmans, You require 1 each of the hoses and cut to length required as one side is longer than other going to the heaterd
