Pictures of how I changed the overheating radiator on my 87-95 Nissan Pathfinder.
Rig overheats on hot days when the AC is on going up a hill on the freeway. Otherwise it is pretty good, temp gauge below half way most of the time.
I read on nicoclub forum that if it overheats in traffic, change the fan clutch, and if it overheats on the freeway, change the radiator. That makes sense to me, so I am finally changing the radiator.
First I removed the skid plate. Four of the eight bolts holding it on are still there.
The other four got bashed the hell off long ago. I should grab some next time I go to the JY.
Then I tried to drain the coolant out of the leaky as hell draincock.
About half came out the hose and into a bucket,
the other half out the draincock assembly, through the frame, and onto my shoes.
I removed the upper radiator hose.
The aluminum giong into the engine is a bit corroded. That will have to be cleaned up.
Then my son helped remove the screws holding on the radiator fan shroud. I think there are four of them.
And I took off the useless airbox faux intake hose.
After sliding out the fan shroud
(mine has no little bracket on the bottom. I would have had to take that off before I slid the shroud up.
I should get one next trip to the JY. But I digress.),
I can get to the lower radiator hose.
And then I took off the upper radiator support bolts.
Note they come off from the other side.
I just put the bolt in backwards so I wouldn't lose it.
And the radiator slides right up and out.
No leaks, just a blockage somewhere inside the corroded gummy crappy 20 year old radiator.
I fixed a radiator leak with that powdered flaky metal gunk years ago when I didn't know any better.
Maybe that blocked something besides just the leak.
The new radiator is a Beck Arnley. All aluminum.
The core is 1 & 1/4", which is 1/4" thicker than the original. Looks good.
And a new lower radiator hose couldn't hurt.
I am damn sick of shitty O'Reilly crap parts, so I went to the knowledgeable, English speaking, at least moderately intelligent people at NAPA.
The radiator goes into the two inner holes here in the radiator support bracket,
close to the condenser, not the holes in the frame.
These grommets needed to be salvaged from the old radiator.
And a new cap to finish it off. Another good NAPA part, made in Japan, the good stuff.
- Next I sold out to make 02¢
so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.
But no minivans!
- Then I finished my beer.
