Just a quick simple question. Now that im actually using the heater sence its below freezing outside i noticed it takes forever for the truck to blow hot air, in the first 10-15 miles its freezin in the truck and i never just jump in and drive it either, i always let it sit and idle for a good 10 min before i leave the house. That and when i turn it on it smells like mildew or old water in the truck real bad. Im starting to think i need a heater core...

well when I was running my 180 thermostat It totally sucked in the winter for heat. Im talkin luke warm heat. I had to have the blower motor on high the whole time and still never got warm. Take that thing out and put a 195 back in if you live in an area with temps around freezing. Theres your problem. As for the mildew smell, you could still have a heater core leaking or maybe your A/C was leaking on the floor but you never noticed it untill It started molding. Or maybe your windshield is leaking around the seams and is allowing water to leak on your floor :dunno:

It was 15 degrees yesterday morning and my heater got nice and hot.
When I had a 160 installed a few years back I had the symptoms you described (luke warm heater).

Philiagorillia: what does you temp gauge go up to?

:wall: Might want to put that on the "to do" list. :D: Would make diagnosing certain problems a little easier.

Im not to sure how to fix that, is it easy to do? It was around august, one morning i went to start the truck and the gauge never popped up like it usually did, and its never worked sence. The truck has never gotten hot or ran bad or anything though. I asked my bro and he said it could be just the gauge itself pooped out, common sence stuff i guess...

I don't have my truck here (at work) or I'd run outside and look, but it should just be a simple 1 or 2 wire push on connector hooked to a sensor somewhere on the block.

I am sure somebody on here knows the exact location, but I have the same truck (2wd version) there aren't that many wires under the hood, shouldn't be too hard to find.

Once you do find it, there are 2 ways to test:
1) you can have the key on and ground the wire (if 2 wire setup do not ground, jump the 2 wires together) going to the guage to see if the guage moves or not. I believe it works on resistance, the less resistance the hotter the temp. So grounding or jumpering the wires should peg the gauge inside.
2) Get a mulit-meter, set it to ohms, and hook it onto the sender. The resistance should decrease as it gets warmer, if it reads open, or doesn't change then you know it's the sender.

Hope this helps some.
