Overheating

[Vic Butler]

When running my BGT stationary on the drive, the electric fan cuts in like others just to the right of the 2 dots, cools the system and cuts out. See my earlier post about what happens under road conditions.

Dave,
The profile of the rad looks normal,just a strange set up with the fins,unless it is due to reconditioning of some sort.
I don't get what the additional fan on the water pump pulley is doing! Is it being used in place of the spacer ring that holds the pulley in place. It would distort if the bolts were just used to fix the pulley to the flange on the water pump + the bolts would be too long.
Curious also as to why the breather pipe doesn't go into a Y piece & then each pipe join the carbs.
Cheers, Charles

Vic,
Dave & I continued our discussion by private email rather than divert from your thread issue.
Cheers, Charles

Due to recent events no update on the overheating. I haven't done anything yet. I hope to as soon as possible.
Cylinder head removal is on the cards.

An update. I've drained the coolant and disconnected the hoses and linkages but with a new puppy arriving, things have been put on hold.
This morning I rang Peter Burgess and spoke to Simon. He thought it was puzzling situation and suggested I do a compression test. I said I had and told him the results which he said was ok. He asked me to send an email detailing the problems which I will do. He said they would inspect and recondition the head if possible, if I sent it to them. I'll postpone removal until I hear back from them.

Vic's resurrection of this thread prompted me to reply to this radiator question from Dave (long since resolved I suspect).
The division in the rad core is typical of a Serck Marston recored radiator - looks exactly like mine!
I guess if they didn't have a core to fit exactly they could simply make some sections fit, works fine.

P.s. Vic - hope you get this issue sorted out soon.

Only resolved due to the fact that due to the virus, I am not doing much driving in traffic conditions that induce overheating. However I still think that the cooling is marginal. For example, if parked up having a chat with the engine running, it is only 2 or 3 minutes before the gauge starts to rise, and the fan cuts in, whereas I can let my Cortina tick over for ages without any indication that things are getting warmer.
I do not lose any coolant, and there are no other signs of overheating.

I've had a reply from Peter Burgess and he reckons it's a cooling issue as, like I thought, coolant would be expelled if the system was being pressurized.
Years ago I had overheating with no water loss. It turned out to be the impeller drive on the water pump had sheared. When I've got the Land Rover mobile I'll remove the pump and see.
It happened suddenly like now. The only thing that puzzles me is why it doesn't overheat when run stationary.

"the gauge starts to rise, and the fan cuts in,"

I may have missed more details on the thread, but can I just say that the above statement is not overheating. It is the cooling system operating as intended. Provided the fan then keeps the situation under control there is no problem.

The point I was making David was that 2 or 3 minutes tickover, after a run, before the fan cuts in is not very long. Hence my thinking that the cooling system is marginal. My old Peugeot 206, now long gone, could tickover for 15 minutes before the gauge started to rise.

It could be of course be that I do have a fault with the cooling system.
