Ok now it's just screwing with me. 97 Ranger cooling help please.
Ok so a few weeks ago, I changed out my timing belt. I bought a new water pump, because I figured follow the golden rule and change it out with the belt. The guys that I changed my belt with, told me, "Don't worry about it, it's not tied to the timing belt, replace it when it goes out" So I drank the kool-aid and took it back. About a week later, I noticed that when I am at a stop and idling, I lose all my heat, and the temperature gauge drop down below the C. Then when I get going again, or I rev up my engine a bit, and hold it at a higher rpm, the heat would return. Same with when I would be in gear and driving down the road.
Now I'm not to smart when it comes to vehicles. (I'm sure yous knew that when I drank the kool-aid lol) But I kinda of thought of the problem along the same lines as I had before on the multiple alternators I've been through. When they start to go out, and your battery light comes on, you can rev up the engine and maintain a higher rpm and make the light go away, and the alternator gives out it's last bit of juice before it's over.
So that's what I've been doing until I can get the water pump changed. If I'm stopped, I manually maintain a high idle speed I guess you can say.
So right before I started writing this, I went and picked up a new water pump and thermostat (figure I might as well since I'm in there) Come home, pull it in the driveway, and nothing lol The truck held its temperature like there was nothing wrong. Kind of like a bad kid who got busted and was trying to act innocent lol
Anyways, what do yous think is going on?
97 Ranger 2.3 ltr no AC
Shooting the breeze with a buddy of mine, made me realize I should shorten the story a bit.
I lose all heat when Idling. Temp gauge goes to C, and heater blows cold air. Not once has it even threatened to overheat. It just acted normal after buying a new water pump.
