Is this modification require on all Subaru engine or just the EJ. Does the FB and FA engine require it?
I did this mods same as in your video and you're right it does pull coolant out of the engine into the heater core but then I had another issue no air conditioning
I have a 2013 and boy how i wish you did too since im about to do the same upgrade but im cylinder #3. Your videos are so well done i wish you had more cars to work on.
Do you have to remove the bolts that are located on each side of the oil pan that have a torx head ?? Hope fully you can reply
Why don't any of you subaru owners know about the petcock valve on radiators… way less mess and much easier to work with.
Probably the best tutorial I seen on this install. Great video
Thank you for showing me how to swap the coolant in my 2018 sti the dealer told me they wouldnt do it!! I have 0 mods on the car just a daily driver but i like to keep my fluids fresh
First of all why did you clamp off the cooling mod hose when you filled the system? secondly there is no reason to turn the heater to max, it was done in the past when the heater circuit was controlled by a valve, newer cars don't have this valve as coolant is always flowing through the heater core.
New version of the GDT has a L shaped hose for that bend
Please provide more cat footage.
Hello from Kent Washington !!!
What front lip is the one you have ? Dope video bro
Would anyone happen to know if this is done the same exact way on a 2017 Forester premium w/ 2.5 L engine or is the hose set up slightly different?
I don’t understand why you kept the cooling mod hose pinched off while filling it up initially? Wouldn’t that result in more air in the system from that much area of the mod being empty? Or all said and done, is it much easier to do it in sections since your getting rid of majority of the air bubbles first?
I've watched a LOT of videos recently regarding Subaru DIY (timing belt and GDTcly4). This is easily one of the best. Regarding this mod in particular, I haven't seen anyone show/perform the hose modification nearly as well as you. I was specifically looking for this before I hacked into the wrong hose, can never be too sure! I'm confident now, thank you.
I’m sure that you don’t have to pinch the hose.
Just wondering why you blocked off the cyl 4 mod when you added coolant?
1 question man, which mod did you do first, the koyoradiator or the cooling 4 mod?
