Engine Cooling problem
1991 Toyota Pickup 4 cyl Four Wheel Drive Manual 134k miles
I recently replaced a leaky heater hose, lower radiator hose, thermostat, and radiator. Things seem to be working fine now except my truck is doing two things that it did not do before: when it warms up, the temperature gets really hot, almost to the red, every time and then cools back down to normal. I assume the engine is warming up and then the thermostat is opening, but it did not used to get that hot and I'm worried that something is not working right. The other thing that is different is that when I first start it up, it is idling pretty high, at like 2200 rpms, and then once it warms up it idles around 1000. Again, this doesn't seem like a big issue but it didn't do that before so I want to make sure I didn't screw anything up. The only other thing I did while I replaced all that stuff was clean out the throttle body a little bit, but I wasn't able to get out much of the gunk in there. Does it sound like everything is OK or should I be worried about the high temp & high idle before things warm up?
have the same problem?
