Hey guys I just replaced my OEM radiator on my 1998 LX accord after 220k miles!

New one is DELCO and is all hooked up. I noticed two high pressure lines on the bottom of the radiator, and what appeared to be tranny fluid dumped out of it. I hooked everything back up as it was and added coolant into the new radiator. I just ran the car for 15 with full heat on inside the cabin until the engine got up to temp. Ill look tomorrow am for any loss of coolant in the overflow tank and add if needed.

a.) is there any special techniques I need to do to bleed the coolant
b.) is there anything special I need to do for the transmission fluid (bleeding?)

Thank you!

 

A) 4 or 6-LX I'll say 4-use the bleeder on the t-stat housing to be sure. sounds like you are ok
B) check fluid level using proper procedure, add fluid as needed-suggest Honda trans fluid.

 

the question is why did u change your radiator because it was over heating maybe??? or because it was bubbling on the overflow???? or becasue when u first start your car you notice some smoke comming out the exhaust?? anyways just do what the other guy said and for the coolant open the radioator cap and squeeze hoses so bubbles travel up to the cap. but if coolant keeps going missing put 2 and 2 together

 

it was leaking a lot of fluid out the plastic/metal seams. Didn't ever go past half way on the temp gauge though, so head gasket and all is fine.

I noticed the overflow tank went bone dry on me, and then saw the radiator was all wet.
