Coolant leaking around timing belt cover

Postby fischerj » Sat Oct 22, 2011 10:47 am



I just had the head gaskets changed and now there is a leak around the timing belt cover.

Any ideas?

Thanks,

Jay

No water in the timing belt covers..most likely from upper water hose, or it's connection on the engine block..or the cross over pipes on the top of the engine which were removed to do the heads..
HAD LOTS OF GOLDWING 75-83

Hi All,

I found out that my coolant tube is leaking due to corrosion. Where can I get a new coolant tube and how hard is it to replace it? And where can I get one?


Anyone have any photos of this area?

I appreciate any help with this issue.

Thanks,

Jay

You sure it's corrosion? These tubes often leak, and it's usually the rubber O-rings that are at fault.

I would remove them clean them up really well with maybe a tooth brush and take one of those o'rings down to Ace hardware to match it up, they have a great selection of o'rings there [metric too], Good quailty o'rings...I get alot of stuff there, screws, nuts, bolts taps,dies....anyhow it's just an idea....Do as you please... All i can do is suggest... Once I went to the honda dealer for an o'ring and what did they say WE Have to order it.... I stopped at Ace on the way back and there it was...

The place that fixed it, said that the tubes were corroded and the put some liquid metal on it, which didn't last long. Now that I've found where the coolant tubes are located above the cylinders running to both sides, I notice some pooling of coolant. I can also see where at least one of the leaks is coming from. It is around the o-ring area. The dealer replaced the o-rings twice so, I'm ruling that out. I purchased some used tubes on-e-bay and just need some detail instructions on the easiest way for me to do the job myself.

Thanks so much for replying.

you know ...... they are made of metal. I would soldier them up and install new gaskets and orings and be done with it. I think you will have to remove the carbs too. so plan on replacing all gaskets and orings, unless you want to be back in there again.

I found that the coolant crossover pipes can leak at the "0" rings if not carefully installed with a little vaseline on them first ( petroleum jelly).
As the pipes are made of aluminium they cannot be soft soldered and if corroded should be replaced. Buy the correct "0" rings for the job, there are four in total ( two for the left hand pipe and two for the right hand pipe) and are HONDA part number 91301-MB6-003. Their dimensions or 21.9 mm diameter and 2.3mm thick.
Install the pipes with new "0" rings into the thermostat housing first and then attach the right angled connetion to the cylinder head(s.) I found there was no need to touch the carburettors.

Just to double check the fitment of 0rings. Put the 0 rings on the tubes first. Do NOT put the 0 rings in the female part as they pinch very easily when the tubes are fitted. Sorry should have mentioned this before as its a common mistake ( many by me!) which may lead to a leak even some miles later.
