cooling system

Hi guys.. I am at a loss and could use some help. I just bought a 2006 wrangler x 4.0 manual transmission and am going through some repairs. One that came up about 2 weeks after buying was the p0118. So I changed the coolant temp sensor (twice after reading the threads about OEM sensors) I...

My 2002 (125k 4.0L manual) has been very slowly losing coolant for the past 6 months or so following replacement of tstat/gasket and all hoses by a shop. To give you an idea of how slow it's leaking, in about 6 months the overflow reservoir level dropped from "full" about halfway to "fill". I...

Hello all, this is my first post on the forums. I searched the threads but did not find something specific so here I go: It's starting to feel like summer and I wanted to fix the A/C, though that it needed some freon recharge but when I took it to the shop they measured and told me the reason...

So I’m new to the whole wrangler thing. I used to have an 01 Cherokee 4.0 and recently got a 98 wrangler 2.5l automatic. I’m currently having trouble with the cooling system. The first problem that I had was I didn’t have any heat so I flushed the heater core. (No leaks were found) and I also...

The myth There's a huge myth out there that's been making rounds on the Internet probably since the Internet first started. Go to almost any car forum out there, and you'll find a slew of members who like to push the idea that making your engine run cooler is a good thing. Often times they'll...

This is my first post, so I don't really know if I posted it in the right catagory, but here it goes. My Jeep is a 99 Wrangler 4.0 5 speed. The previous owner has converted over to an electric fan. I've replaced the thermostat, upper and lower rad hoses, and even put in a new rad at the end of...

Losing my hair from scratching my head! Although Stinger does not have a jeep engine anymore the general principles remain the same. There is a smell of anti freeze when I turn the heater on. Although my A/C is not yet reconnected to the system when I switch to any of the A/C functions the...

Every now and then you need to temporarily disable an electrical circuit that is normally on. I don't mean that you need to unplug it for a week or two but rather you need to turn it off for a minute and then back on. For example.....the 12 volt cooling fan on my transmission cooler has its...

Question, and I'm guessing it's been asked about 10,000 times on here. About how many miles is the factory water pump good for? 99, 4.0, 5spd, 160,000 miles. When it's time to do the water pump, is like older mopars, check and change the timing components.

This thread should guide you through replacing the water pump and thermostat (optional) on your Jeep Wrangler TJ. Before reading this thread, please take a look at this thread as well, since it's very informative: Jeep Wrangler TJ Cooling System Overhaul FAQ Hardware Needed: You can also find...
