Radiator inlet + amalg

[MattF]

Opinions on this one. Finally managed to dig out some specs on self amalgamating tape:

Safe bet to wrap the radiator inlet with a layer of that? Seems the temperature range should easily cover what it will be subjected to.

As to why, I'm getting coolant creep from the top hose again on occasion under pressure.

Just on a side note in this regard, does anyone know what that thin brown liquid sealant is called, (or who produces it), for sealing water unions? Can remember seeing some of the stuff years ago but can't remember for the life of me what it was called, or who produced it. None of the local factors seem to have any idea either.

Youre not thinging of Stag are you? I remember using it years ago, but would guess that PTFE tape and paste has largely taken over its duties. You can however still get it. http://http://www.alibaba.com/produc...erling_Uk.html

Stag may be the one, the only other thing I can think of is Hermatite?

i had that problem matt
new top hose and clips 14 quid from toyota
stoped mine

I used that self amalgamating tape trying to sort a hose leak on an overheating Omega I used to own.

I just couldn't get it to a 100% seal....the water would always find a way out....whether that was because the tape was sealing against rubber and the pressure was creeping along the rubber I don't know. It worked for a bit, but I could never see it as a medium-long term solution.

May be worth going for a real decent bespoke silicon hose matt, and not doing the hose clip up to tight, it worked on mine

[NiftyNev]

I use Permatex No3 on all hose connections. No weeping ever and is also great on gaskets and bolts associated with the cooling system. Stops corrosion between the steel and alloy making them easy to remove.

When using clamps on hoses put them as close to the bead on the pipe as possible and use wide clamps. There are narrow ones available which are probably made to keep costs down but they clamp poorly and tend to cut into the hoses. Wide clamps (about 13mm I think they are) spread the clamping force over a larger surface area of the hose. Perhaps your problem is just the clamps you use.

14 quid!!! he's have a heart attack

Bugger me Nev. I spent ages looking for a U.K supplier of that when you first recommended it and never found one. You've just put my search skills to shame. Cheers for that link.

I could only ever find suppliers out your way and in the U.S last time I checked, if I remember correctly.

That's a good possibility. I've been using genuine Jubilee clamps, but they aren't as wide as some clamps I've seen. This damned top hose seems to be my bane.

Saw that post over an hour ago. I've only just managed to stop the palpitations so that I can post. Then Graham mentioned silicone hose too. By Christ, they're trying to do me in.

I think I might have got quite a few shonky, (pitted), hose connections, metal wise. I alway try the minimal tightening necessary when replacing any of the hoses, but can guarantee that by the time I've finished testing and nipping them up for leaks that they always look like Samson has been having a training session with them.

Btw, silicone hose? Bejeezuz, how much? Remember I'm a tight arsed sod.

Im so sorry matt, i forgot about the financial "brevity".......im at gatwick waiting to fly back to glasgow at present, i was going for a coffee...spose i better have bread and water now !!

And exactly as nev said, get some wide as you can hose clips,this does make a real difference.

I was having cold sweats, honestly.

Aye. I think I'm going to have a session and give all of the hoses a going over again once I get some of that Permatex sealant. Never been too happy with how tight I had to clamp some of those hoses up, so I'll start afresh and get them all replaced again. At the end of the day, £20 or £30 worth of hose is a damned sight cheaper than the problems a coolant leak could cause.

Which are the best hose clips? I know the local rad chap used to have some wide ones with a slight curve on the edge too to prevent them digging in, but he's retired now so I can't nip round and ask him what they were.

[gwh200]

When i did the 2.4, i replaced all the hoses with a new set. These were from a local motor factor. I cleaned up all the pipe unions, especially the aluminum ones, as they were a bit corroded. I put ptfe tape around the top radiator join as it seemed to "bulk" it out a bit. I used plain old jubilee clips, as the existing hose clips were just two separate 2 mm wide clamps. I used the wider jubilee clip as it spread its force over a wider area. It worked for me matt, and if you use proper pipe sealer you should get a better ,tighter seal, without having mega tight hose clips, ruining the pipe.

[POPEYE]

on most of the hoses i replaced i doubled up on hose clips (jubilee) where ever poss, fit em offset to each other, smeared a bit of silicone grease on the inside and the spigot and alls been well since, mind i had a load of clips and some silicon hoses of verious sizes that i "come by" in the past, only hose i had to buy was for the intercooler over 90 soddin quid
