Ford Ranger / B-Series :: 2000 - Constant Leak From Gasket Between Thermostat Body And Engine?
Jun 1, 2014
I have a real problem with 2000 Ranger, after changing the upper radiator hose and thermostat, I now have a pretty constant leak from the gasket between the thermostat body and engine. Appears to be something that is triggered by the thermostat opening, so whatever the leak, the thermostat is blocking it.
I've changed the gasket, cleaned the mounting surface as good as I could. Tried re-torquing the bolts, but on that score - what is the torque specs for the 2000 3.0 liter Ranger?
But ultimately, what the heck is wrong here? This should be a pretty brainless operation really. Am I tightening the connection too much and cracking the gasket? I guess that has just occurred to me, although the gasket is not as stiff as a typical fiber gasket is.

I just finished replacing the Valve body gasket in my 99 ranger with the 4.0 liter v6 with the 5r55e trans. My problem now is that I have no gears i can shift it but the gears do not engage.. I did install the updated bonded separator plate and the tsb for the blow off valve with it.

So I noticed when I check the oil, there is a very small amount of water at the end of the dipstick and also water mixing with oil around the oil cap. It is not much water at all, but my first thought was head gasket. I was loosing very small amounts of coolant, but found a small leak at the thermostat housing....The truck runs fine, idles fine, no bubbles coming from the radiator at startup, no moisture from exhaust. It seems to be using more oil than normal, but I drive it 100 miles a day still and no major issues other than the perplexing bit of water and oil mixing. Could it be a tiny head gasket leak? What else would cause the water and oil to come together.

I have 2000 V6 3.0 Ranger and it has sprung a small coolant leak from timing chain cover gasket. I think just few drips after driving a while since I don't see significant drop in coolant level (Took a month to notice level dropped in reservoir) and did not see an active leak while idling. No water in the oil.
The proper repair would be to replace the gasket, but for the age and condition of the truck, I don't think it is worth it. Searching for a cheaper solution, I found K-Seal and see lots of reviews with success. Will it damage the cooling system in anyway? I think it would be worth a try even if it doesn't fix the leak as long as it does not cause any harm.

I am fixing the front of my 2000 Ranger? I need to replace everything from the radiator support fwd. I need to know how to get the radiator support out.

New motorcraft plugs, wires, and coil packs. I'm running havoline 5w30 with a motorcraft filter now. I didn't notice the tick when I got it only a few months ago, but it could have been there and not as noisy, I'm not really sure.
I've got some parts to put on when I get time. Probably be a month or 2. I have a timing belt and tensioner, water pump, block heater, drive belt, tensioner, and idler.
It's a constant tick. Worse when cold, but still there warm. Sounds like under the valve cover. I'm not afraid to get in there and fix it, just would like to hear some opinions on what it could be for sure. I've read about the lucas and high mileage oil combo maybe reducing the noise, but if its fixable, I'd like to do it when I have it torn down for the timing belt, which is original I'm sure by looking at it. I really don't like abnormal noises from my engine compartment. Bugs the crap out of me.

I have a 2000 Ranger, V6 4L, and I believe my head gasket is blown, my radiator fluid goes straight to the oil pan. It has probably been leaking for a while, I did not realize it was leaking internally, I had been adding coolant for a few months but thought it was my radiator leaking because it had a crack in the housing, so I had that changed, but then a few weeks after that It gave out. I drained, and flushed the engine twice, and just parked it. My question is, should I just have the head gasket changed, or does it need a new engine because it had been leaking for a while and not sure what kind of damage it has done internally.

Finally got around to replacing my Thermostat because the DIY here made it look so much easier than removing the alternator and such. Did everything exactly as described and after assembling everything with the new t-stat and O-ring I am getting a constant leak from the housing. I tried removing everything and reassembling...all the bolts are tight. Plastic housing isn't cracked and seems to be in great shape. Everything lines up properly but coolant is just running out of the bottom of the housing. Am I missing some magical trick here?

Been having a little problem whenever it rains, the carpet on the passenger side gets soaked through and I'm not really sure where the leak is coming from. the only part of the floor that gets wet is the flat part where the passenger would put their feet, but the parts that slope up towards the dash and towards the middle of the cab stay dry. I've pulled up this part of the carpet, and the rubber grommets are intact and in good shape, and there is no rust or anything on the floorboard. from searching here it seems people have had similar problems, one thing being a leak into the seals around the third brake light above the rear window.
a couple things i should mention is that the air conditioning condenser has been broken for about two years, so could water get blocked up and leak in? since its winter here in PA i haven't used the air con since last summer though. I'm not really sure how long the leak has been happening since I've always kept a floor mat over that spot, and the carpet drys in a few days anyway.
Another thing i should mention is that the weather stripping at the bottom of the window on the drivers side door is not perfectly tight and tends to come out of place when the door is closed hard. this has been happening since i got the truck almost three years ago and a new piece was just put in a month ago (the leak had been occurring before the new piece was installed) when the truck was hit and went in for body work. possibly a drain routing to passenger floor? I should add that I'm sure it's not coolant, it has no odor and feels like water.
Might be a good idea to pull up the whole carpet on passenger's side and sit in the cab during the next storm...

Bought this truck at auction a few days ago. Started drive home and noticed temp gauge almost pegged full hot. Stopped and left it and pickup up later that day with trailer. Got home and started and ran it. Will not overheat at idle. Gauge fluctuates between full cold and 1/2 at idle. Rev up and temp drops to full cold. Drive around town under 35 and it stays between 1/2 and 3/4. Get on the highway and Pegs full hot. Replace thermostat and flushed system. Lots of rusty water and chunks of rust/mud poured out.
Upper rad hose is firm and hot. Lower rad hose is warm soft. Bypassed heater core and still over heats. I can run water hose from top hole on radiator and water crosses threw radiator and pours out the bottom so I don't think it's clogged. It's not the head gasket, I have no smoke, no milky oil and no oil in coolant. Fan clutch seems fine, I can spin it with the engine off and feel resistance. Truck hasnt boiled over while running hot so the gauge may be wrong. If it means anything the truck runs very rough and pulled up a misfire on cylinder #1 and had a iac code.

I have a 1997 4.0L Ranger with an oil leak. It is near the front of the engine, I don't really see where it is. I was wondering if there is any common oil leaks near that general area?

Is there any way to repair rust spots so the rust will not return aside from putting new metal on it? I've used Bondo before but it rusts again after a while.

Changed my oil today. Noticed oil coming off the front of the engine. Where this could be originating or do I need to take the belt cover off? I hate having a leak. Wanna get it to stop. Just need to know what I may be up against. 1996 2.3ltr.....

2002 Ranger XLT, Super Cab, 4X4, 4.0L SOHC V-6, 5-speed manual transmission. Noticed burnt oil smell. Checking under truck revealed oil drips on garage floor from rear area of engine. Traced to rear corner of left valve cover, but can't see enough of the rear of the engine top-end to say for sure where it may be coming from.
Before I put the truck in the shop for repair, where the oil may potentially be coming from on this particular engine? (I checked; the valve cover fasteners are secure) Any "chronic" oil leak problems with this model engine, or anything?

I recently discovered that I have a small leak due to the oil pan gasket beginning to tear. Due to my 2001 Ranger being a 4WD the quote to replace it is almost $1000 since I was told they have to lift the engine to do the job. I only lose an ounce or two a month it seems so I could just tolerate that unless someone knows a way I can safely plug the leak. It is actually pretty easy to access the leak as it is right in front of the pan as you face the engine from the front.

I have read all I could find on replacing a blown head gasket and and after absorbing everything that TigerDan posted on here, I dove in and began. After disassembling all the topside junk I finally got the intake manifold loose and got down to the head. I began undoing the head bolts and found two broken bolts. The head won't budge so I am calling in a cherrypicker. I don't know what kind of mess I'll find when the head comes off. I assume the head will be warped or the block may be damaged.

1991 Ranger STX, 4.0. Had a leak from the rubber seal on the thermostat. Changed the thermostat (stat 195) and seal. Now my temperature gauge is not showing a constant reading, goes to half way and when the thermo opens the gauge falls down to a quarter. The gauge is cycling this way every time the thermo opens.

I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.
After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.
Other things which may serve as clues:
Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)
When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.
Car has 107K manual shift.

I have a 1983 ranger with a YFA. I recently took it apart and in the process of the rebuild I noticed the metal gasket was still in the spot where the needle pin goes. It has adhered to the carb. Any way to get it un-stuck? Also, there is a module, and the gasket comes in the rebuild kit so I know it belongs, the part number begins with 2I3 but the rest came off with the dirt. What is it for and would it hurt anything if it wasn't plugged in? It hasn't been since I bought it.

My son and I were doing a transmission flush and while we had it on the lift, I noticed the oil pan gasket was sticking out in the front quite a ways. I assume its time for a new one. Is there anything I need to know having never dropped the pan on this truck? Is this a common issue?

When driving down the road, there is a constant "thud thud thud" coming from the front driver's side of my 99 Ranger. I've been looking online for about two hours now, going back and forth to my truck to see if I can figure out the problem. All I've come up with is that it's the sway bar links. they're both disconnected, and I'm going to replace them anyway, but would that cause the constant thudding?
