Thread: D1 over-heating at times

Hi,

Does anyone have a wiring diagram for the back of the instrument cluster and showing where the earth / ground wires should be terminating.

Thanks

You mention an airlock? Where exactly would the airlock be happening?

Thanks

standing at the front of the engine looking back, on the right hand side of the engine is a steel tube with a riser on it and a (plastic or brass) cap, it's about half way along and above the rocker cover. This is the highest point in the coolant system and is there so that you can bleed out any air that is trapped in the system. run the engine so it has positive pressure but not hot crack the cap if coolant comes straight out no problems, otherwise wait until it does (keeping an eye on the collant level in the header tank)

Thanks for the info.

Tried finding the riser you referring to and unable to locate it.

Attached is an image of the engine if someone could point me in the direction where the riser should be located.

Thanks

Unfortunately ... your model does not have it ... They had it in that position up till about 1995 'ish ? ... LR deleted it & extended those 2 black hoses




To bleed a difficult air pocket ... Find a hill / or a set of car ramps and get the nose of the car up in the air

Start it and warm it up to temp

Take the bleed bung on the TOP L/H side of the radiator to get all the air out of the radiator ... as this will now be the highest point
Massage & squeeze the top radiator hose to help remove the air



Just out of interest tho .... Does the Heater in the cabin work well ... or does it just blow luke warm air?



Cheers

Check your timing
I had the same problem for the last couple of days

It turned out my dizzy had come loose and backed of the timing causing it to overheat

Not boil just run a little hotter than it should

it also caused the car not to start it would just click


I moved the dizzy about 3 degrees anti clockwise and problem solved

Hi Mike,

It's only blowing warm air, doesn't get hot.

Also, if the temp are on hot and I switch the sitcom switch on, it starts blowing cold air. Also the temp gauge starts showing cooler than normal (like it's reversed)

Thanks

Hi Mike,

I purchased the gauges you recommended.

Unfortunately the Temp probe doesn't fit on the D1 temp probe chamber.

Have you managed to fit it (assumption is you purchased the gauge )

Thanks
Shaun

my temp guage got hot when the earth strap from the battery was loose,tdi but worth a look
