  1. I am puzzled with this issue...any help is greatly appreciated. Purchased this Toy home in 2011 at 55k miles. Brought it in Concord Toyota for head gasket recall in 2014. The dealer replaced the timing belt and water pump at the same time. It put in a wrong AC belt and left a tube of black silicone by the radiator (another story). In 2015 on a trip from Yosemite while encountered some heavy traffic on I580, I noticed the engine temp climbed up to about 3/4 of the way. Otherwise it remained cool (fluctuated between 1/3 and 1/2 way on the gauge). From my experience the 1st thing I did was replacing the fan clutch (after market) and while at it, I replaced the 180 deg. Thermostat and most hoses. Thinking that this solved the problem since then we didn't take the Toy home far away...just some short trips around the cooler Bay Area destinations (typically less than 100 miles round trip) This weekend we took it to Lake Tahoe area and I noticed after refueling while waiting to get back on ramp, the engine temperature climbed again to the 3/4 mark in about 100 degree heat; otherwise it runs cool (fluctuate's between 1/3 and 1/2 mark). The fan roars well when hot eventhough I have no way to tell if the new fan clutch is working well or not. The thermostat is new. The radiator and condenser area is clean of debris. Turning AC off doesn't seem to make a difference. I notice that climbing a 30deg slop on the 1st gear at 25mph is still OK (temp. Gauge at 1/2 mark or slightly above) but not all the way to 3/4. Normal fwy driving at 70mph is fine. Are there any other tests I can try before either replacing the fan clutch again or the radiator? I will try to idle for about 30 min when getting home to see if it over heats
  2. At long last, after replacing my plugs, wires, distributer cap, ignition coil, and fuel filter, I have discovered the cause of my Dolphin failing under load and idleing rough; the Idle Air Control Valve. Unfortunately, this part has been a booger to find. Does anybody have one for sale or know where I can locate one? Obviously, salvage yards are a good option, and I've been to a number of them, just haven't found a 22re with the part still in it.
