When i only had the 734 bbk on the grizz i was able to still keep her cool with the fan running all the time it was easy to keep the temps under 212F with stock fan/radiator. Since the motor rebuild to a 778 and the HOT weather i’ve had two rides where it was really difficult to keep the temps down.. The ride that i listed in my other american star CS thread I was floating 225F during a steady grade to the top of the boise foot hills that day it was about 97F outside with no wind and no clouds in the sky. I know from experience that the engine temp light turns on about 230 and you have potential to break open your thermostat at around 227F. I was really close to that but the temp light on the grizz never came on.

This last Friday i finished the new tierod install "which was much easier that I thought it would be given the allen head bolt on the hiem ends" and yesterday i took the grizz out south of my house a few minutes outside of boise for a test ride. I put on a quick 38 miles and the tierods are nice and solid. I got back to the house sprayed down the grizz and let it just sit drying off as i sat there drinkin beer. I then started her up and let the grizz get warm around 170F then parked her in front of my garage door in the driveway. I sat down on the pavement tossing a tennis ball for my puppy when i noticed i was loosing antifreeze out of the grizz 🙁 Looks like i blew another water pump seal!! I’m sure its from getting to hot the ride before this one.

She’s now back in the garage and half torn down .. I’ve got on order an aftermarket 3 core radiator and a spal HO fan along with new waterpump seals. I should have just done this from the beginning but at the time i just didn’t want to tear apart the front end of the grizz as well…

The wrenching continues on this ol’girl……… I should have known i wasn’t finished :cussing:

If there’s interest i’ll post up pics along the way of the new radiator and fan install and any difficulties i run into.. It appears to be a good bit bigger than the stock radiator I hopefully wont have any issues with the install.
