NPB 646L - Update

Post by tomcat » Thu Aug 11, 2011 7:56 am

Hi there
Picked up my white (was green) IMP Super yesterday evening. MOT till next June.
It is in need of some TLC and will get some upgrades over the coming months.

One thing that I was a little apprehensive about was the 'irregular' behaviour of the temperature gauge.
Stayed just in blue zone for ages. Then crept up to about 3/4 point and seemed to be moving on from there, be it slowly.
I was on the M25 at the time so eased off and it went to about half way. Then when I was doing 30, or so, off the motorway it was back down in the blue zone.
Is this usual behaviour?
Intend to go through all the posts on "Cooling".

Regards
Tom

Hi Tom,

well as another Tom said 'it's not unusual' :D Sorry

Yep searching the cooling posts will give you an idea where to start.

For starters gives the rad a good balst through with a hose externally to clear any muck out of it. Give it another go after and see if it's improved. It's also worthwhile giving the system a good flush through internally and refilling with good quality coolent mix. If the history of the rad is unknown I always assume it gone passed it's sell by date and routinely fit one of the easily obtainable HE rads.

Hope this gives you somewher to start

Cheers

I always check what thermostat is in the engine as I have bought some cars that have had them removed for whatever reason (it can hide some engine problems temporarily) it should be a 74 but some use 82 or 88, worth checking

Good luck with your purchase

Hi there

Thanks for the comments.

Sadly my bank balance is not the same order of magnitude as the other Tom referred to, so we will take things one step at a time.

The weather has decided that pictures and further investigation not possible at the moment.

Regards
Tom

My prediction is that the thermostat is removed and that the rad is blocked internally.

As Rich mentions above, the first thing I always do is replace the rad as a matter of course - unless the car is known to have had a replacement HE rad in the recent past. I treat them as consumables...

I have just purchased a 'spare' rad that I could get reconditioned.
Is there someone recommended for this work please?

Malcolm Anderson or Ben Boult do them by exchange by post (I think club spares do too, but never used them) - I wouldn't bother with anyone else.

Serck Marston have a good reputation, I believe. They seem to have multiple locations, including one in Northampton.

EDIT - You want the 3-core design, I believe.

My first Imp had symptoms exactly as you describe. The thermostat was partially seized (I tested it in a pan of water on the cooker) and the radiator weighed about twice what my brand new replacement HE unit from Malcolm weighed! :? That's a lot of limescale! I only use deionised water in my Chamois now - mixed 50% with blue antifreeze. (Comma because I cannot seem to get Bluecol locally. :roll: )

Your new rad ought to do the trick. Give the water pump and cooling fan a good clean too, replace any suspect hoses and test the thermostat, although you might as well replace it too, to be honest, for the relatively small outlay and peace of mind. :) Then you should be good to go.

I am planning to replace everything whilst I am at it :)
Point about deionised water noted.

Picture of engine bay.
Found one could just lift the earthing clamp off the battery :o
Battery is on charge as it 'just' spun the engine. Went straight to 9amp rate on the charger.
Am planning general tidy and clean up in this area.

Miscellaneous electrical items.
Replacing complete dash with Sport item.

Re: NPB 646L - Rear Window Woes

Post by tomcat » Mon Sep 19, 2011 12:23 pm

After the recent heavy rain I found that water was entering at a good rate!!!
A previous owner had used about 2, maybe 3 tubes of sealer and then jammed the lock as well.
Decided to get the window open and replace the whole lot with one purchased recently.
New seals from 'Imp parts' were also obtained.
Careful use of a knife eased round the frame got it moving slightly.
Further efforts finally eased it open to reveal the horrors around the frame edge. :o

The mechanism works OK and keeps the window up and open.
However I am unable to release the 4 screws for the top hinges and also the side nut and 'screw' mechanism.
I do not seem to have a flat screwdriver thin enough to fit in the slot. Any thoughts on getting these items undone please?

All comments appreciated.

HE Radiator is now fitted with new hoses as required.

Welding has been done on the passenger side engine cover hinge area so it is now solid metal. The cover opens and closes as it should.

Front windscreen has been replaced with a new item complete with rubber surround and chrome insert. This seems to have cured the water problem in this area.

I have been working very slowly on the rear opening window area. I am still unable to remove the 4 hinge screws at the top. The idea of drifting out the pin to get better access was a good one, but it looks as if the end is turned over. More thought on this. :roll:

In the meantime have been cleaning up a replacement window. Finished up with 2 purchases, one with a HRW set-up. So careful cleaning with a Dremel, then etching the area with 'Metal Ready', followed by 2 coats of PQR 15, then primed and a couple of thin coats of white to seal the surface. Not concours by any means but good enough as a step forward. :)

I have purchased a complete set of seals, including 1/4 light ones from Australia, so the bank balance has been hit badly. These will get fitted stage by stage.

Existing seat belts were a nonsense so new ones obtained from Quickfit.

Next job is replacing the dynamo with an alternator so have been carefully stripping out the loom in the engine bay.

More to follow.......

Not very much has happened over the last 2 weeks as I have been down with a very bad stomach bug.

However yesterday I managed to get the final bits on the dynamo to alternator conversion done. Have gone the route of stripping out all the 'old' wiring and also incorporating additional wires for reversing and rear fog lights.

Fingers crossed turned the key and the car started and lights that should go out, went out. :D

Feel well chuffed, as I do find electrics a bit of a mystery. :roll: :?

On to other things now.......!!

As the weather was clear and bright I decided to have a go at getting the complete dash out.
Took about 2 hours in total. :)
Was very careful with sorting out which things I had to remove and which could stay. The main puzzle was the bottom rail of the dashboard past the steering column.

So now I can access the wiring plug to the printed circuit. As I am utilising the instruments from a Sport have the voltmeter and oil pressure gauge to incorporate.

Little task for later this evening comparing the 2 wiring diagrams :?

I could be wrong as I did this a long time ago , I seem to remember that no 7 connection is empty on a std Imp , i got a spare terminal from an old loom and wired the volt gauge via this .
As said its a long time ago so do check

I have been upgrading the electrics and planning to add some extra instruments and a DIN CD/MP3 player.
I have had the complete dash system out to upgrade to the Sport version one I purchased.

Basically have added 2 fusebox system, 1 at front and other where the control box used to be.
These offer permanent live or ignition switch controlled options through a relay.
I use a Lucas 4FJ fusebox as a distribution box with 30 amp fuses.

Wiring for auxiliary fusebox is as follows:-
Feed off battery through 4FJ to Terminal 30 on relay.
Feed from Ignition controlled 12V supply to Terminal 86 on relay
Permanent Live Fused Accessories are then run from Terminal 30.
Ignition Controlled Accessories are run from Terminal 87
Earth is via Terminal 85.

Not 100% there yet but coming on.
