heater valves

[idc1873]

How long/how easy is it to change heater valves.

Dont know if its same as mine with the heater flaps up the rear of the engine but if it is they are a doddle just get dirty thats all from putting ya arms up there!

they're easy to clean up and lube in situ, removing them could be a big pain in the ass. The mounting studs are part of the chassis and often shear when you try to remove the nuts. So you end up trying to weld new studs to the chassis.

Hi,
All of the other replies are fine but if you need to replace them as evetually they do sieze solid and the heating is then very poor indeed.
To minimise the shearing of the 6mm nuts that hold them on you need to remove th engine and gearbox to get maximum angle of attack.
If they do shear it will be difficult to weld studs back on so people tend to drill out the stud and use a self tapping screw.
My advice is to wait until the engine and gearbox are removed for another reason and then tackle it then.

cover them in a rost of spray from wurth, its called crafty rust off. i used to work for them and i know how good it is. it will disolve rust in front of you making it easier to free the nuts off

Heard about this Wurth stuff before any ideas who stock it , local motor factors not heard of it

could be various things Darren. They should switch on when the dial is set at 4 and above, but they will only work if the main blower in the engine compartment is running. They do often burn out and are sometimes are just left or replaced with a section of tube. Could be a fuse, could be the heater control unit between the seats. I would in this order:

Check all fuses, even if they aren't blown replace them or give them a wiggle in the holder
Check the main blower in the engine bay is working
Check they are actually in there
Check they do actually work, either remove them and test on a bench or rig up a direct supply
Check the heater control unit, they do fail and I'm not sure how repairable they are

Note that there are fuses located in the wiring right by the blowers themselves - 10A if memory serves correctly. These were later 'blade' fuses on my 88 car.

I had to replace one of my blowers which physically appeared OK - i.e. spindle turned freely, no obvious signs of damage. Fuse was blown but blew again, following replacement, immediately power was applied to the blower. Replaced the blower with a new one and problem has not re-occurred.

idc1873 Try the relay in the engine compartment (LHS) this is the one for the engine blower motor. It failed on mine, the again I'm sure the footwell blowers still worked at that point.
