Access to top of 1500 engine

Postby macaroni » Sun Mar 24, 2013 8:18 am



I have a very small coolant leak on the top of my 1990 1500SE. I have removed all the panels and fairing pieces, but can only barely see the top of the engine. I can see coolant puddled but thats about it. What do I have to remove to get access to the top of the engine? Manual says carbs but I cant get to the clamps to loosen them to pull the carbs out? Do I have to remove gas tank; radiators? I know that once I get access I will change all hoses and o-rings and thermostat.

I found the easiest way is to pull the fans out which requires pulling the plastic to get to the fans. For you if you have a leak, you can drain and pull the radiators which requires pulling the front plastic.

Before pulling cooling system parts out leave them in as long as possible while trying to determine source of leak. Once there out you are then committed to replacing every hose and/or connection for a successful repair. Trust me you will want to find the one leaking hose or fitting and repair that, they are a bear to get to everything not to mention all the different metric pre-formed hose sizes. What side of the engine has the leak, that alone will narrow it down somewhat.

When trying to locate source of leaks always start at the top and work your way down. Reserve bottle, heat riser beneath carbs and radiator filler cap area first after checking front of radiator area. Then fans out to eyeball back of radiator area and more hoses.

I have been deep into my bike and would seriously consider the purchase of a pressure tester as a last resort to find the leak source before yanking all the hoses.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

Sounds like good advice. I hope the weather starts to warm so I can get to working on it again. I am anxious to get it out and disappear down some unstriped roads. Thanks for the advice.

The water pipe hosing is actually fairly clean its getting through all the vacuum hoses that is though. A couple of places to check is the pipe at the top of the radiators it connects the two together and the ones at the tees- again replace clamps . It will not normally be the largest pipes - replace all clamps you take loose as they can cause leaks. If you decide to pull the carbs which will make your task easier - check all your vacuum hoses for hardness they should all be soft but have spring back. If you find a bad hose you can replace with same size hose from the auto parts. I replaced all of mine with silicon. the pre-bent ones off the intake manifold are the only ones I got from Honda.

I just replaced all the hoses on my 88. As posted before, these are metric hoses. None of the auto parts stores in my area carry metric hoses like this. Some of the Honda hoses are no longer available. I was able to get other hoses with the same bend and cut them to fit. It seems from reading posts from this site and other gold wing sites that the O ring on the one pipe goes bad and causes most leaks. I replaced all my hoses because they were 25 years old.
