This install is on an 88 Ranger. Your vehicle may vary but the general ideas are the same.
1st off - follow you vehicle manufacturers recommended safety instructions for safely and properly jacking/lifting your vehicle. We're not discussing safety issues here, you are responsible for following safe work practices .
2nd - dispose off used coolant in accord with all local/state/federal rules.
For this project I needed:
Large tote for draining coolant into. I like the ones that can slide under a bed, low profile but wide and big enough to catch the coolant.
Enough new coolant and water to refill.
A lower radiator hose coolant heater.
Sharp cutting instrument.
Start by draining the coolant. Make sure coolant and engine are cool. This truck has a drain plug on the radiator, but not all do.
Take off radiator cap to help drain.
After all that is going to drain drains, I pulled the lower radiator hose off. Here's a couple pics.
After the hose is out you need to cut a small section out for the heater. I'm starting with about this much:
You want to cut it out on a good, straight section of hose. Pretty easy to find on this ranger.
More after work...
And I have to buy the heater too, Haha. Hopefully they still have one in stock. But I had to get the hose off and measure it to know which size to get.
