The "Heater Core by-pass" was one of the first creature Mods I did (02). When you can cruise around in 100+ heat, with the fan on low.. in by-level mode.. It's gota be a Good.. Thing.
I got the dieselsite.com kit. All the pieces & parts.. 1 hour job.
for anyone that wants the ranger valve. its can be found on a 97 3.0l ranger. cost is $18 + the 1/8" t fitting and 3' of 7/32" vacume line so $20
any vacume operated heater valve with the right size inlet and outlet will do. cut one out at the junk yard for $5
My 03 7.3 had the factory valve on it, so Bob Riley sold me the Cold Rush. When I go to the SJ Valley for my town job, it gets over 100 easy. I now cant use the Max AC setting...and I like it cold in the truck!!!
Install was a snap, too.
dieselsite rocks!!
I think this is my next mod, after I check to see if I have one already installed. If I already have one (which I doubt) then I will go with the Cold Rush upgrade. Wish I had seen this earlier!
I was going to get on but my truck has it already, so I change the orifice tube to a smaller hole size and the system gets colder. I still not happy with it. It's fine at night or when overcast it well freeze you out of the truck but at hwy speed it sucks.
The PSI on both side are dead on. I dont know, thinking a undrive unit. Any Ideas???
