Hi ALL Again!

OK, tomorrow I'm buying one of those "Inline" flush kits. The last time I did this....it was the UPPER heater core hose you spliced into! Well....I was going to pickup one of those kits. Thinking 1 size fits all! Well it DOESN't ! I was asked what size the heater hose was? Well.......I've never even thought about my heater hose till now! I opened the hood......WERE IS IT? Under the spare??? OF course ....it's a Subaru!! So, there is NO upper and lower! Just left and right! WHich hose do I splice into??? Does it matter!? Is the inside diameter really only 5/8? These cars are weird! But they do run a long time, make weird noise too!!!

 

 

HELP!!!

 

Many thanks, SubeeTed

Use 5/8 tee. Tee goes in the heater inlet hose. That would be the hose that goes to the aluminum water pipe. The outlet hose goes to a black metal pipe that goes straight into the waterpump.
