1990 1500 coolant seep

Postby 702scottc » Sat Nov 22, 2014 1:55 am



Seem to have developed a very slight coolant seep at the LF corner of the engine. Started once the temp dropped below 50 degrees at night. Only a drop or 2 but I can smell it once the engine is warm.doesnt leak once it's warmed up. Any ideas where to look without shredding off all the Tupperware?

The lower hose from the radiators nor the water pump is leaking. I'm thinking it might be the y pipe from the top of the water pump to the heads, manual shows breeze clamps near the heads. Hope that's all it is. I'll have to remove the lower panels to see. It's not a big problem, more of an annoyance than anything. Guess folks in the cold country deal with these cold water seeps a lot.

Yup, those crappy hose clamps they use at the factory just don't do the job after a number of years. I had the same thing on mine, I pulled the hose clamps off and replaced them with some quality stainless hose clamps, the problem disappeared and never came back.

Do you have any photos (tutorial?) on this process --? I suspect this is happening to both of my GL1500's ..

You can see the process on How to remove and replace your timing belts - all the steps up to step 32 deal with getting to the hoses, draining coolant, and removing the hose clamps. At that point you can then just install the new clamps and reverse the process.

Finally had some time today to pin down my coolant seep. Removed the side panels and radiator fans and found that the thermostat housing is seeping ever so slightly. A job for another time. No way to get to it without removing the air filter housing. Even with the fans out of the way can't really get your hands in there.A good weekend project, gets dark too early now, sucks.. I have a new t-stat and o-ring. I did remove that pesky hot air intake tube, really blocks access on the left side. Useless in the southwest so it didn't go back on.
