Dean, just keep cranking or if you are brave, give it a sniff of brake cleaner but be bloody careful as the engine can run away and it might not stop!

Daz, when it cuts out, get out and release the filler cap and see if there is a large inrush of air past your hand.

Thanks for all the help on this. A squirt of easy start and it fired straight up. Now it's back to starting and running as it should. Except the bloody temp gauge isn't working now so no rad fan kicking in!!

Check fuse SB38. Does your car has a lower radiator outlet temp sender? The G62 on the head is plugged in isn't it?

I've checked the voltages at the plugs for both g62 (head sensor) and the lower sensor on the rad and both have 5v supplies to them.

I replaced the head sensor this morning. However i drove the car today in 25⁰ heat and it struggled to show 45 on the temp gauge.

I've not been able to find a diagram with fuse sb38? I did find the big 50amp flat fuse for the rad fan which is good.

Engine bay fuse box, they are numbered.

**dean.st** · 23-06-2020,07:30 PM

my fuse box is part/type number 335624830. All fuses are numbered F1 through to F30 with some unused. There are 6? very high amp bolt on fuses to the front but are un numbered and they range from 50a to 200a.

There is 1 relay, was 100 but now 644.

One more symptom is that when the gauge finally shows some heat, removing the connections to either or both of the sensors makes no difference to the gauge at all.
