Replaced the radiator, big hoses and clamps several weeks ago. Noticed that my coolant level was 1 liter (~1 quart) or so low every few days but never saw a drip. I'd smell antifreeze while driving on hot days but never see a leak. Got worried it was the head gasket again or heater core. Replaced the radiator cap and tightened up the constant tension clamps on the PHH and all the new clamps for the big hoses.
The other day after a quick trip I noticed a substantial drip from the rear of the engine but could not spot the leak and it stopped after 1-2 minutes. Got back home and topped it off after cool down. Took it out tonight for a test drive and sure enough after 10 minutes of highway driving I came to a stop to check for leaks and there it was again. Drove back and put it right up on the lift. Took off the driver side front wheel. A HAH! Pinhole in the hose that runs from the head up to the throttle body. Sneaky, very very sneaky.
Had to notch the aluminum angle on the side of the radiator at bottom below the filler to clear the core support and radiator mounts.
Have to add a small nipple for the bypass hose the runs to the head behind the distributor.
The fan shroud mounting holes have to be moved over a few inches.
The lower outlet tube is 1/8" smaller than the factory so you'll need an extra hose clamp or make another lower hose.
I already had a trans cooler in front of the radiator, so not having one in the bottom of the tank was not an issue for me.
