My 1994 Suzuki Swift Sedan 1.3L with 280,0000 miles has been running cold for a while now.
I can't get my self warm with the heater in the mornings when there is frost. It surges climbing up a mountain. The most annoying thing is that the indicator for the temperature needle will go up and down as the car accelerates and decelerates from middle to low in steps. I thought the old thermostat would be stuck open but it was not. I am unsure if there is some small problem that is creating this issue.
Does anyone have a solution to this issue?
I used this procedure to install and remove the thermostat from the chilton book
this is after getting answer. So found the sensor near/at thrermostat housing. one wire comes of it. grounded the sensor to the chasis with alligotor clips. Flip the key swittch on/off and it did climb the temp coolang gauge to hot.
actually after just messing with the connection it started to work alone. It was just corroded! :) the outside sensor's connnection
