I've got another situation here with my bonnie. Already have a problem with a slight heating temp of the engine, probably my coolant temp sensors which is being dealt with for now. After driving for a while, stop and go, traffic.....(New York City), I shut off the engine. When I start the car again, she barely wants to start, I guess that'* what you call a HOT START or what?!

Is this because the engine temps are to high, due to the coolant temp sensors going bad, or what? Every ten minutes I have to keep my eye on the temp gauge, which is annoying. According to the service manual for this year vehicle (198, it states that driving for a while would cause slight temp readings. Temp gauge sometimes reads at the 3/4 mark and almost to the red line which is not good.

Again I 'm hoping it'* the coolant temp sensors.
OK dudes and dudettes, hit me with your best shot on this.
Thanks again.

sounds nothing like the coolant temp sensor but low coolant levels or blocked coolant passages [most likely in radiator].

If you haven't already, check your coolant level in both the radiator and in the overflow bottle.

If that is the case, I have had the engine up to about 3/4 on the gauge and the car stalled and it too did NOT want to start, not for the life of her. Pumped the gas a little and she stumbled around but eventually fired up. It'* the heat, the coolant temp sensors are probably working just fine. Best way i've found to cool down a car, turn the heat on. that easily kills 1/4 on the gauge if too hot.

Are the fans coming on, at 3/4 (I have never seen mine even to 1/2) both should be on HI. If the fans do not come on at slow speeds the temps can go through the roof.

oh yeah, totally forgot about the city. if they don't, to test the associated wiring [minus sensors] is to do the procedure to extract codes from the ECU. This trick apparently doesn't work on 91, and i don't believe 90 either, but it works in my 89. Hopefully the 88 too. ANyways, jumping A and B turns on both the high and low speed fans..

There are two fans, but I didn't know that they both should work at two speeds. I assumed the smaller fan was for the AC, or heater? Also what is the best way to flush the radiator of the rust and mess? This would be a great solution without changing the sensors. Something had to be done about this. .

Removing the lower radiator hose will drain the most of the coolant. Flushing is a little more difficult, i'd personally just run straight water for a couple days then drain that again, and repeat. Some will disagree iwth running straight water, but I do it, and have had the same water in my radiator for two or three months... it'* still real clean. Once my car is treated to a couple gallons of gas, I will fire her up... for the first time in a month, and clean that crap out, but I guarantee you that'* some real clean water. Just gotta make sure you use distilled water... tap = crap
