This DIY was written as an informational guide on how to remove the radiator from a sc300. I used these steps to remove a the radiator from my car while i was doing other maintenance. I will have other DIYs that start from after i did these steps so this is a good place to start. This was meant to be used as a guide to help and I am NOT responsible for what u do in your own time. Be safe, work smart, and please use common sense

1. using a jack safely lift and support the vehicle on jack stands


2. using the petcock on the driver side of the radiator, drain the coolant. hopefully yours was not broken like mine. hence the speedy dry


3. remove the intake hose from the throttle body using a 10mm socket and ratchet as seen in the picture. there are 2 vaccum lines that need to be removed as well


4. remove the battery, and battery tray. IMPORTANT NOTE!: DISCONNECT THE NEG (-) TERMINAL FIRST AND THEN THE POSITIVE. WHEN INSTALLING CONNECT POSITIVE FIRST AND THEN NEGATIVE. FAILURE TO FOLLOW THAT PROCEDURE COULD RESULT IN ENGINE ELECTRONIC DAMAGE.


5. remove the upper radiator hose, remove the 2 10mm bolts holding the air shield, and the 4 12mm nuts holding the clutch fan to the water pump (best done while there is still tension on the belt.)


6. remove the lower radiator hose and the 2 transmission cooler lines. the OEM ones on mine were 19mm, my replacement radiator came with 7/8" lines that I choose to use. Note some transmission fluid will come out and it is best to check the level when new radiator is installed

7. using a 12mm socket and rachet, remove the 4 bolts (2 on each side) holding the top of the radiator and carefully remove as coolant and transmission fluid might come out.


8. To install, reverse procedure. If you are continuing on with other maintenance then continue on from here

 

Interesting, from what i remember when i did mine all i had to do was..

Drain the radiator
Remove Top and bottom hose.
Remove 2 lines that go towards the automatic transmission (If you have one)
Remove the fan cover, should be 2 clips
Remove 4 bolts that hold the radiator down.
Yank on it till it pops out.

Then just put everything back how it was

 

yes the step of taking the fan off can be saved if you are very careful i put it in for the following reasons

1. not hard to take the fan off and pull the shroud so you dont knick the new radiator
2. this DIY will be used in conjuntion with another to do the valve cover gasket

thanks for the input though

 

someone should do this for the 400 bc gah lee its a beotch

 

Yeah no problem.

I remember when i did this i basically winged everything. Those clamps are a PITA i yanked it out and the coolant spilled everywhere. My whole body was soaked with coolant

 

my clamps came off fine it was the hose that was welded to the plastic and now u now why i had speedy dry on the floor! lol i was also covered in coolant

 

I need to remove my radiator and replace with a new one. Ijust want to know is this the same DIY procedure to do for a SC400 1992 as well and is it really complicated?
