Hmm, I have an ‘01 P38 and my return hose drops around the battery. Perhaps I’m misunderstanding. In any case, I tried parking up the drivers side on a gutter and ran it for a bit. The coolant seems to be circulating again, I noticed some coolant dripping from the return hose and I think it was...

Ah ok. I thought I read a post somewhere about cranking hot air assists in burping coolant.

So I installed all the new things and it seems coolant isn’t circulating properly. I couldn’t see it coming back into the overflow tank. Well, I did see it initially, then it stopped. Also, I seem to have completely lost power to the HEVAC unit and radio which is just amazing :mad: So I wasn’t...

Yeah it’s a strange one. The rad doesn’t look munted though, unless it was hitting the old rad. I couldn’t see it hitting anything when it was running, probably would have made an awful noise that would have been hard to miss. In any case, I have a new rad, fan, viscous coupling and thermostat...

The plot thickens! Or maybe it doesn’t… check out these photos I took of my fan. It has the same-shaped chip taken out of every blade in the same spot. It doesn’t look like it was done from the factory. It is as if the fan has been hitting something while it was spinning.

Hello :) I can’t seem to upgrade my account. The PayPal link is broken!

But what else am I supposed to do while I wait for my new cooling parts :cool:

Right! So the boiling over through the cap is a symptom of a bigger issue. Like a dud viscous fan or blocked radiator as others have mentioned earlier on. A couple friendly members suggested probably a blocked rad, not just the viscous fan. If the rad was properly blocked, wouldn't I get the...

Howdy folks! If I ever get ye olde P38 running reliably :rolleyes: I was hoping to invest some time into sprucing up the interior. I currently have a dull-ish grey interior and I quite like the black on black that can be found on the HSE specs. The plastic parts are easy enough, I'm fairly...

Not sure if I'm being overly optimistic here, but it is possible that all these woes could simply be caused by my expansion tank being warped and not sealing the cap properly? Or would that not really explain why it only overheated while at a standstill/lowspeed and was fine while traveling on...

Also, any idea why on earth there was sand/dirt in my radiator when I flushed it out? Is that a sign of worse things to come? :confused: I put a couple photos up on the previous page.

Is programmed an English word for tuned? :D Well I do like ice-cream and coffee.... and there is a place down under that does all alloy rads that apparently fit the discos 2. Maybe I could find one for a P38. :rolleyes: As for the OBD-II shennanigans, I have an '01 P38 V8 petrol, so I was...

I like your optimism :D I just got myself one of them trendy Bluetooth obd2 readers so I should be able to get a better idea of temps!

The hoses have since been replaced, though I don’t recall them ever getting outrageously hard. I did check. as for the expansion cap off test, I do recall a time I didn’t screw the expansion cap on properly and coolant came flying out the overflow hose after idling for a while. I’d have to...

Oh dear! How did you manage that? :( That is one thing I’m worried about, I haven’t really gotten to the root of the fat hoses. Would be bummed to replace the cooling system to find a cracked head or similar.

Back flushed the rad today. Water came out pretty grubby featuring some sediment and rocks. Now I’m no expert but that doesn’t seem great. Half tempted to just buy a new rad, thermostat and viscous fan and call it a day.

Allllrighty! It's been a minute but I finally got time to remove the radiator & viscous fan properly after having to wait for an order of a spanner that would fit :rolleyes: They both look in okay shape, the bimetal strip isn't gunked up or anything, though it doesn't turn a whole lot when I...

I did add rear main seal stop-leak fluid to the engine oil a couple of months ago! Nothing in the coolant itself, though.

So here's a fun discovery, I found a receipt for a new radiator 2 years ago as well as a new radiator cap. Surely things wouldn't have gunked up already? Could you please explain what you mean by "level the coolant" I'm a bit of a noob :D Thanks for the tips!

I removed the cowl, that was fine, but the plastic housing that goes around the rest of the viscous fan was obnoxiously large and in the way. As for the coolant flow, I have indeed checked it. The method for removing the air was to squeeze the top rad hose, then, while depressed, place finger...
