replacing top hose on rover k

[Tim Broyd]

I've replaced the hose, but on running the top hose gets hot whilst the bottom hose into the radiator says cold.  Seems there's still air in the system.  How do I get rid of it please>

Hi Tim. You need to release air from the highest point in the system. If you have a heater, air possibly trapped in there. If heater valve open ... both the heater hoses should get equally hot. Have you got a bleed tee inserted into the uppermost heater hose ? Have you got a bleed bolt in top of radiator header tank ?

Bottom hose only gets hot after thermostat opens. Did you run it for long enough ?

Do you have a heater? And do you have an additional bleed tee?

It's a very common problem. In addition to bleeding at the highest point(s) possible there are enthusiasts for all of the following:

• Lifting the nose.
• Massaging the hose.
• Drilling a hole in the thermostat.

Thanks SM25T.  I haven't got a bleed tee or bleed bolt.  I opened the heater valve (was closed before) - both heater hoses got equally hot and after quite a while the bottom hose into the radiator got hot as well.  Hopefully that's fixed it.  Many thanks for your help.  Tim

Should have said - Thanks Ian.  I've done precious few miles over the last 3-4 years cos of too much work, especially overseas trips during the summer.  I'm hoping to remedy that this year, starting with the Fish'n'chip run.

Thanks Jonathan.  I thought putting it up on ramps, but was too lazy :-)

Great to hear you'll be on the F&C run Tim. We are driving west, leaving Dartford around 1100 on Friday if you want company.
