What's your budget?

If anyone's out there (....?) wondering if this is an ok replacement radiator? (Ignore the fact that it's a German website, I'm there ATM) https://www.daparto.de/Teilenummernsuche/Denso/DRM51005?modelId=a9e9a380

Ha, definitely not. It's a leak in the plastic housing on the LHS. Pretty common. Was gonna J-B Weld the 4cm crack in the plastic and find a decent radiator. Considering replacing it myself.

Evening all. I've been through the multiple threads on leaking radiators on the 400h. I'm heavily assuming I need to replace it (see pic). But two questions: 1: do I need to replace the whole thing. As in, does it come with that broken bit as standard? 2: can I patch it up as a temporary fix? (Context: noticed the coolant was low, then saw the crack, weeping slightly. No obvious signs of heavily leaking, no pink stuff anywhere, no overheating) Cheers in advance

Many years after this thread last stopped, people are still having this problem. I had the same problem this week (sometimes the system wouldn't work, sometimes there were only a few haphazard guide lines) so for anyone else who comes across this thread, I fixed it by disconnecting the 12v battery and reconnecting it. Essentially the old "have you tried turning it off and on again" trick. I suspect it was connected to me getting a new battery installed a few weeks earlier.

I thought it would be easy to get parts from breakers for the Rx series, as there's so many around. I needed a couple of door cards & other interior bits (previous owner had kids). But I had to do a load of eBay messaging & calling till I got what I needed at a good price.

Yeah I saw similar prices. If I could buy one for £12.50 i would. Metal prong? On mine it's a yellow plastic pop stud. If you lived in Russia you could get the full set for £25 https://baza.drom(blocked word)/novosibirsk/sell_spare_parts/kryshka-rejlinga-zadnjaja-lexus-rx330-rx350-rx300-zaglushka-87081643.html

Glad it's not just me. And they're crazy expensive for some cheap plastic. And yeah I was stupid, didn't know there was a middle bit. All but one of the clips broke. Guess the plastic gets brittle after a while. There was crap and mud inside, so once that's gone I'm literally gonna use clear bathroom silicone, just to stop it flying off.

As an aside, in my quest to find the leak, I accidentally broke some of the tabs on the luggage rack end (a long black plastic piece). Thought I'd see if I could get one cheap off eBay. No chance. Mega expensive. Stupidly so. Looks like I'll have to get the clear mastic out for it.

Quick update. At the wrong time of year, in the wrong weather I used some random German car filler a few days ago to patch up the most common areas for leaking. I was not particularly delicate about it as I don't care about the aesthetics. having had heavy snowfall since then and a fair amount of rain, I can confirm I can't see any leaking at the moment. I'll do a better job when the weather gets better but at the moment I just wanted to stop water getting in

Of course it did. And yours is particularly bad. Plus when you search for "water leak 400h" & come across page after page of problems it can feel like everyone's having the same issue, but I'm going to guess it's usually pretty rare. It could also be an age thing; they're not getting any newer. I've liked the 400h enough to look at it's successor when the time comes. There's a lot to be said for Japanese reliability.

Other than the water, is there anything else that ended up being a PITA? I've had it a year, and nothings been a problem yet.

I can get back at a push, but need to do work stuff here. Brexit is making a total mess of my business. Need it like a hole in the head. But your leaking sounds pretty terrible, compared to mine. I didn't mention it before, but when I got the car there were a few tide marks on the wall boot area wall (solved with warm slightly soapy water) so it looks like a previous owner had fixed a few old leaks. Seems like every car has its own specific problems that only get discovered once *I* buy it. My old 1999 7 series bmw liked to have the bowden cables snap. All of them, at one time or another. And drink oil. Fun times. But good luck mate and report back on your progress, maybe pics if you can. It might prove handy for others (or likely me!) in the future.

Ha! Didn't know you could get full 400h covers. Full disclosure, I'm stranded in Germany atm until I can get back to the UK and we had a few dry days so I grabbed the chance. Ordering Tiger Seal was gonna take too long (and three times the price of Halfords) to deliver, so had to get what I think is the German equivalent called Petec k&d. The weather has been colder than the recommend application temperature (why do these things always happen in the middle of winter?!), but there was snow and rain coming, so I've filled the most obvious 4 weld joints and will report back with pics.
