How do replace heater core without new heater core?
THE HUNGARIAN WAY
One year ago I noticed a leak in my Heater Core - the coolant ran out. I found several ways to repair it - but it takes a lot of time. Changing the heater was not an option - I did not want to disassemble the whole Jeep.....
Jeep dealers and spare parts do not exist in Hungary. So I was looking for a solution from the hardware store .... and found it ... water installation parts
1.5 meters water hose 18 mm
3/4 inch connections
3 meter gas hose (yellow) - flexible stainless steel pipe
insulation material
fittings
Note: I do not have a garage or work space. The jeep stands in a public car park of a hotel. Tools only from a cheap Chinese hardware store around the corner!
It works well - the jeep gets warm enough in winter to get the windscreen ice-free.

That was my first attempt - only 2 Meters of gas hose (Unfortunately that was not enough for the heat output)
Then I experimented a bit with extensions and L-angles (all 1/2 inch). This is the final version.
The connections to the water hose go through the rain drain into the engine compartment. There, the hoses are connected to the already often described bypass.
Shorten the cover cap with the cutter :
and in the end you have this final solution
no guarantee, but it works fine for me
