So I had to jumpstart my Disco and wanted to let it idle for a while to charge up. Came out after ~20min and noticed there was fluid on the ground. I popped the good and it appears to be coming from my coolant reservoir. I had marked the level a while back with a pencil and it looks to have dropped about 1/4-1/2". My Ultra Guage showed an idle temp of 201 in the garage.

Any ideas / thoughts or reasons to be concerned?

 

when is last time you changed yo coolant cap? tstat? bad cap or recent flush junk could clog stat

 

The coolant cap appears to be new. PO claims to have done it shortly before I bought it.

I just did a system flush of dex, replaced with Peak mixed to 50/50, switched to 180 stat ~2wks ago.

 

could you see if it was forcing out the overflow tube? should have seen green in there, if so.

 

It happened while I had stepped away and it was idling for those ~20min. It had stopped by the time I returned. So I grabbed a flashlight and looked around inside and it appears to have came from the tube.

After looking around to see the origin, I started it back up and let it run for another 10min or so watching to see if it did it again. It did not and before that 10min was up it had stopped dripping underneath. So I don't think anymore was coming out.

 

i'd just keep an eye on it, next few outings. fwiw, both my d2 have their preferred fill level lines, neither are the factory line, but about a 1/2" low. when too full, it forces coolant out the overflow till it gets to that spot.
if it happens agian and if you suspect the overflow, you can stick paper towel in tube to see results

 

I can do that. Thank you sir, for the time and help!

 

I agree with Dusty1. The reservoir levels seem to be a 'rough' guide. If I fill mine to the max cold level after a couple of trips out the level has always reduced by 1/2" and always the same - never more and never less. I've checked the reservoir pressure cap and that's fine. The fluid just expands when hot and disappears out of the overflow pipe. Put some hand wipe tissue paper on the end of the overflow pipe held with an elastic band or thin wire and check whether it's wet after a trip out. That will tell you where the fluid is disappearing to at least. (that tip was, I believe, from Savannah Buzz who I thank for the idea)

 

That's a great idea! I'll try that out.

It's good to know I'm not the only one and it's probably nothing to worry about. I hadn't driven it much since the swap and I had topped off the coolant a few days ago. This was one of the longest run times it's had since then especially sitting still.

 

First, your alternator is not made to charge a battery like the old generators, so don't waste your time.
Second, never let your engine idle for 20 minutes with the hood u, you are not allowing the engine to draw cool air thru the radiator and it will over heat.
So, go have your battery/charging system test at a local parts store, it is usually free and you need between 13.6 and 14.4 volts under a full electrical load.
