Hi All

Don't know much about land rovers although think they are brilliant fun! I purchased a 91 defender for some fun at weekends etc about 2 months ago and no major problems although the defender has had a fair amount of work done prior to I bought it. It has 62k on the clock and been checked / serviced etc.....

Since I have had the defender it has probably done around 800 miles as quite like driving it!

I drove the defender about 60 miles this morning on a run towing a small trailer and then drove home later this afternoon, about 10 mins into my return journey I was going up a hill on dual carriageway @ roughly 60 mph when I noticed a spray coming from the under the bonnet and hitting the windscreen. It was green and looked like coolant, it lasted for about a minute and maybe only a cupful / pint coolant was sprayed up! I stopped and there was no steam and the engine temp was normal and the spray had stopped. I then drove another 50 miles home again on a dual carriagway and the engine did not become hot or change temp from normal infact it ran really well! Got home and looked under the bonnet and a small about about of green spray under under the bonnet but nothing major and no obvious source. Could it be something to do with the hill?

Anyone any ideas please?

Thank you

Was the expansion tank for the coolant overfilled? It could have over pressurised if this is the case and the excess was dumped out by the pressure relief in the cap

Thank you Chezvegas for your response, not sure if was over filled or not as did not fill it although my concern would be why has this not happened before as have done around 800 miles in Defender.

The little black tank which I guess is the expansion tank only has a small amount of coolant in it now at the bottom but there is some in there. Do I add coolant and water 50/50 to fill it up? Sorry I am stoopid.

If it was anything more serious would I not of broken down the engine overheated?

Thanks

50/50 top up to the line will be fine - might be worth unscrewing the thermostat housing brass (or plastic) filler screw as well to make sure no air locks

The take it for a drive and see if it repeats

Thank you for your help, will try topping up and another run. Last night I did notice some coolant at the bottom of the escape valve so I guess this is where it came from!

Really great forum helping idiots like me who know nothing about LRovers but learning.

I can compare the Defender to being like having my first car and having to carry around a tool box wherever I go. Makes every trip an adventure!

Thanks again
