Coolant leak
« on: September 12, 2019, 05:14:33 pm »
Let my 99 Tipper sit for a day ( was out of town) came home to a small puddle of what appears to be coolant. 26k new to me only put about 300 miles on her.
Looks like it is coming from the small bit of hose that goes from the water pump to the engine.
Can I just replace the small bit without a fluid change? Is it that simple? Hope you wise sages can guide me.

I have photos but I need to resize them before I can post

You could do that if you want.  Unless you know that the cooling system has had a flush and fill recently, I'd probably advise just draining the system, followed by a flush with distilled water.  Refill with the std old green stuff.  It looks like you've got a shop manual of some sort.  Follow the directions from that.  If you have more questions just ask.  Don't forget there is a bleeder valve on the side of the thermostat so you can get the air out of the system.  HTH :)

You could start by tightening the bolts a bit and see.

It is good practise to replace all fluids right after you buy a used veh.

The bike is new to you so you will find many other issues that need looked into. Low milage bikes are desirable but many times they were never serviced. Were your valves done?

By first glance, those clamps look brand new to me... I'd tighten them both, and check on the results for right now...
then follow up with any real replacements if so desired..

Looks like the clam could slide down to the very end of the hose. Might help.

The end of the hose looks to be a little large in so far as id. (pic 1) I wonder if the PO replaced the hose with a section of heater hose in the wrong dia.  I had to do something similar while on a trip when the hose started leaking while on a trip. I used a section of 1" heater hose from NAPA on a Friday afternoon. Ordered the correct hoses after the  trip. That hose will be the first to fail on the bike as it is behind the headers and gets overheated. All the rest of them may look and feel good when that one is dry and hard.

Went out this morning and no new puddle. Couldn’t get the clamps to tighten or loosen with a screwdriver. Got the socket set out and was able to get about a turn and a quarter on both clamps. Took her out for a bit and waiting to see if anything drips. The hose was definitely replace right before I got her and the diameter of the tube is larger than it should be. Thanks for pointing that out. Replacement tubes and full flush are on the to do list.

Haven’t checked the valves yet have but I did watched all the YouTube videos about it. Going to wait till it starts to rain before I do any jobs that big. I have to reinstall the stock air box and replace a few thing to make my bar risers work.

Thanks for all the quick responses I don’t know much about wrenching but you guys give me the confedince I need to get out and bust a knuckle or two.  :beerchug:

The hoses can leak a bit when cold.

I think you will have it sorted out soon. My bike still has very low miles but when I bought it the PO had never done the valves because he said he hardly rode it. Usual story with low milage weekend bikes. People just get lazy or kick the can fwd.

My valves were a little tight. You should check them soon and change out all the fluids.

Now, why are you Jason from Hell? Something we should know?
