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: Flat screwdriver 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.
