Just got back from a short ride to notice there was blue coolant dripping (more like a slow pour) out the bottom onto the garage. I have a pic where it looked like it was coming from. Any ideas on where to check, or what might be causing this?

This is an '06 F4 with only 3,700 miles

The overflow pipe ?

 

[chrisbanks00]

I went to add water (it's all I had at the moment) to the coolant tank located under the ignition. As I was pouring it in I noticed it was flowing out of the tube shown in the middle of this pic.

I'm hoping someone can educate me on what this might all be about...if needed I'll take it to the shop....

 

[gotojoe]

well that is the overflow tube Chris so you had probably overfilled the header tank, that's all.

I did not recently change the coolant. this coolant has been there for well over a year now. Can this just happen out of the blue? I'm hesitant about taking it on the road to far from the house...

Chris, coolant being pumped out due to overfull systems are well documented. Make sure your bikes is upright when you check coolant level, DO NOT fill past the MIN level.

Maybe the weather was just warmer on your ride this time. Maybe the coolant was not coming out of your overflow pipe when you where riding, but rather from the tell-tale hole at the bottom of the waterpump. It's easy to confuse the two.

 

[theknurl]

leaker?

probably the overflow like Joe and Donsy said

but it could be the water pump, there is a weep hole at the base of the water pump where the pump goes into the cases, on the bottom side, look for coolant stains

there appears to be a drop of oil on your drain plug.....check the torque on it and the pan bolts they are notorious for loosening because of where the side stand mounts

MVs like to mark their territory with coolant after a hot ride. Both my 750 and my 312 have done it. Fill the reservoir a bit above minimum and go for another ride. When you get back home, pop the fairings off and watch for drips. More than likely from the coolant overflow. Just keep your level at or just below the minimum mark and you'll be fine.

As for the possible oil leak, check the two 6mm Allen mounting bolts that hold the side-stand mounting bracket. I just had to tighten them on my bike because I had a couple drips here and there.

 

[chrisbanks00]

Thanks guys. Sounds like a great opportunity to go ahead and pick up the water pump and fan upgrades.

 

[J_Spec]

They work wonders. My 312 has them and it's a surprising difference. Riding in traffic in triple digits is still exhausting, but it's much better than with the plastic fans and factory impeller.

Best of luck!

Water Pump Questions...

I'm about to order the upgraded water pump and fans, but have a couple simple questions first...this is for a 2006 F4 1000S

* The two pumps I see are the official MV OEM pump, and the Design Corse pump. The DC pump is more then double the cost, but is it worth it for the average rider?

* If I'm replacing the pump, I may as well replace the fan blades too. Would I just need to pickup the two aluminum fans?

* I see GP Racing has the MV Pump, but I only see fan blades for 2007 MV Agusta F4. Are the blades the same for 2006 and 2007 models?

* I'm located in the States. Is there a local company anyone has purchased the water pump and fans from?

 

[Donsy]

Without sounding blunt.
1. Yes
2. No relation, the pump and blades have noting in common, the plastic blades WILL melt.
3. 2002 to 2009 blades are the same.
4. Blades ! Muzzy.....
Try the search function, or just read some ...... !

So, the plot thickens. Took the bike out again for a short 10 mile run. Temps were around 60 F outside. When I got back to the garage, I noticed "white steam" I guess you could call it coming up from the front of the bike. The fans were also running and the bike temps were 217-220F.

Not sure where this steam was originating coming from. By the time I realized what was going and taking my gear off, it stopped.

Is this potentially going to be a cracked radiator I've been reading about on this forum?

Hi Chris,

When the outside temperature is hot these bikes don't like being stationary. In fact they don't like it at anytime really....There is one thing that cools these bikes more efficiently than all the upgrades in the world...Rapid movement of the machine through the air stream..That provides a nice cooling due to heat exchange at the radiator. I am sure other riders will agree that you can ride real hard and so long as the bike is shoving air the temperature will be fine.

Keep out of traffic !! lol or..

Fit Muzzy fans,
Put engine ice in the cooling system
Samco Silicone hoses,
Do the Mitchy manual fan over ride switch so that you can bring the fans on earlier if stuck in the traffic.

With regards to the water pump, I fitted a oe impeller and casing kit . The upgrade impeller has a much better set of vanes on it.

But most important..fit a Radiator support bracket from me as the rads are useless without coolant inside them...lol

Then fit a Upgrade Rear Hub from Mitchy and you won't be afraid to give it the beans .

Have fun..and yes the guys do report back that those DesignCorse water pumps work very well so you kinda pays your money and takes your choice

Thanks Donsy...I can deal with blunt. Yea, my problem is I think I actually read to much which ends up clouding my poor brain. I'll go ahead and order the Design Corse pump along with two Muzzy fan blades from the sponsors on this page.

gotojoe....I sent you a PM regarding the bracket. Thanks!

Affirmative Chris..This is quite likely...I just recommended in your other thread that you get one of the Radiator support brackets from me.

Good news is you can get that rad repaired fairly cheaply at a rad repair shop...

Top man : )

Samco Silicone hoses

Do the Samco Silicone hoses actually do anything with the overheating problem, or are they mainly for the "cool factor"?

 

[gotojoe]

according to the sales blurb Chris they actually dissipate heat better than stock

Details on how a bracket gets more coolant into the radiator?
