Good evening
When I pulled up outside my house tonight,I could hear coolant leaking under pressure from the tee under the drivers side near the rear heater. Could anyone recommend the best way to repair this as I can’t see anything in the members area I have attached a photo of the leak.
Thanks Stephen

HI, common problem, but you don't say which engine, the piping varies a bit between them, however is it a metal pipe or a rubber pipe? Simpler if its a rubber pipe or a seal to a metal pipe that has failed! Best to check the diagrams for the cooling system and/or rear heater from the diagrams available here
http://lushprojects.com/bongopartsmk2/ Replacement parts from either eBay or one of the dealers can normally help;
These companies do a range of spares, not all will have everything so try them all;
For smaller parts its probably best to ring companies as not all the smaller parts make it on to the web sites!

Hiya
A bit of an update after looking through past posts on here, I worked out how alter the pipe work to remove the leak and rear heater bled the system which was the bit i wasn’t looking forward to but went surprisingly well.
After a week of use I have had no overheating or lost any coolant so all seems good.
This is the 3rd time I brought my bongo back to life just using information on this forum.
So thanks everyone
Stephen
