why would a2008 mercury mountainer blow off the hoses on the radiator?
We have a 2008 mercury mountaineer that has blown the hoses off the radiator twice. We have heard a noise that sounded like a bearing going out. We think it might be the water pump because we have replaced the radiator cap. We have also been told that the mercury mountaineers with are particular engine are known for blowing head gaskets. Can you help?
Yes....hoses are made from inferior quality butyl-rubber...if you're serious about keepin' 'er on the road for more than ten years would switch to Silicone rubber....blue like the kind you'll find under the hood of police interceptors known for reliability and not reducing under compression of the hose clamps and blowin' loose- will shop for you----
They arent known for head gaskets in my opnion. Do you have a 4.0 or a 4.6? I guess it could be a head gasket causing too much pressure but the cap is meant to hold a certain amount and release any thing above that pressure. Only time ive had hoses blow off is when the clamp either wasnt on or weak and not holding. Did you get the correct cap?
you're the 90 point #1 Mercury Mountaineer Expert, kbro....did you actually ever own/drive one of these....'tis crazy, I'm an "expert" on cars I'v e never owned....when you're good, you're good....I guess!
Ive drive/work on a mountaineer/explorer almost everyday at work.
The hoses are weak and need to be changed. The clamps arent the best but we put brand new clamps on the hoses. The radiator will over heat after running for about 5 mins. You release the radiator cap and a ton of steam will come out. what do you think?
we have 4.0
Either have lots of air in the system from not being bled correctly or head gasket.
Well we were told by a guy at lithia ford to take out the dipstick and put a lighter to it and if it made any bubbles and crackling noises that it was a head gasket. We did that and nothing happened and the oil smells normal. How do you bleed the system? We o=have only have the vehicle four 4 months.
Is there a cap actually on the radiator or is there a remote resviour with a pressure holding cap?
remote resivour with pressure holding cap and we have a cap on the radiator as well
if I'm not mistaken the 05 had the remote tank with the pressurized cap
we are talking about an 08 mercury mountaineer. The radiator has a cap and there is a resviour with a flip top lid on top of the resivour tank. Does that help
Gonna need to get a spill free funnel. Google it and it will provide picture of what it looks like. It needs to be attached to the radiator and filled with coolant and run the engine an air will come out because you will be at the highest point in the system. Turn the heat on inside the car and get the rpm's about 1200 to 1500 when you have all the air out you will be getting good heat out of the vents. But you needs to keep an eye on the funnel an keep it full and make sure it doesnt flow over which it will tend to do until the thermostat opens. If the bubbles never stop coming then you have a bad head gasket.
Yeah the flip flop lid doesnt hold pressure thats just the overflow jug. The cap on the radiator holds the pressure.
ok thank you so much for your help
Your welcome. As always its much appreciated if marked helpful! Gotta keep my rep up.
@bradley you may be thinking if the 4.6. Pretty sure all the 4.0's have the cap on the radiator. Most other model fords have the jug you are referring to.
kbro....you aren't THE NEW NUMBER SIX...are you?
The new #6?
Oh you mean in the rankings? Im not even top 10 waaaaaa
You're the number one mountaineer guru, though...by a lot~
you've got the right idea though, answer everything and if you know that your advise were followed, good things would happen~
Currently sixty reputation points away from number 4, next to tenspeed, DavidH25 and Tom Deyman...quite honored and really don't know from thinkin' on me toes~
The translucent overfill jug/reservoir is that way so that you can see the levels indicated FULL level about halfway up and COLD about a quarter of the way up...filling it up to the top will result in spillage~
Kbro....dude! you're number 12, just behind John Saffran....oooo, I'm scared~
weak waterpump to where the veins have worn off to where coolant flow is restricted.
