Probable H/G failure fix journey of a novice

Well ???

Good luck! ... though in the pic not everything is where it should be...at least the crankcase breather is not

I did remember this and is now on

Well.....

Firstly there was a leak around the new thermostat.... I hate those clips!

Secondly the starter was just clicking and not turning over.... After a couple of minutes and about 30 turns of the key she came to life.... Spluttering at first and then smoothed out.

It looks like I have some work to do on the solenoid

Before the h/g change the pressure in the top pipe got very hard very quickly due to the bubbles coming into the expansion tank... Now it is just squishy and no more bubbles. Need to take her on a run later today and see what happens

Thanks for the support!

Good luck with the road test. My own Td5 defender has been off the road for about four weeks now, and awaiting action from the mechanic. He has all the parts (I had/have similar overheating problems as you described) and just getting around to fitting them. Then, and only then, will I know if the problem persists or is fixed

Took her for a longer journey and all was well. The nanocom was showing coolant temp staying between 84 and 86. When I had the limp mode kick in it went up to 117.

I've whipped the starter off and ordered the repair kit so hopefully that will come early next week. Then I had a trip down south for work as the first real test!

a missing pipe from the crank pressure wont over heat the engine as it now allowed to breath direct to atmosphere this is as healthier for the air intake but it will make a mess ...where is the viscous fan

I did forget the fan....!
It's on now, but thankfully it was a cool day so it made no difference to coolant temp.

I also took the starter apart and cleaned it all up and it starts with no problems now. When my repair kit gets here I will change out the contacts though.

The starter is quite easy to remove

i doubt that cos there will be depression in the crankcase at high revs without that pipe that's why the depression control valve is fitted on it

I have had once where my depression valve had failed blocked up resulting in high crankcase pressure the oil in my turbo wasn't allowed to drain quick enough resulting in damaging the turbo lucky I had a spare chiniese turbo cartridge ..while I waited for a new valve coming from the UK I drove the car in all conditions with my breather pipe into a catch can and then out to atmosphere ..and plugged the hole or the air intake temporarily until my new valve arrived

the 2 weeks I drove I never over heated even it the middle of summer here in Australia

well I'm happy to report that it survived a 230 mile journey south - I had the Nanocom set-up and the coolant temp stayed in the 85 to 86 range the whole way.....so looks like it was successful. Lets hope it lasts now!

Need to refill the a/c....can I do this as DIY or is it best left to the 'garage'?

Filling the aircon is easy if you have the gear to do it. If you don't take it to a garage, you won't want to be spending £250.00 on gauges, a vac pump and refrigerant.
