I have a 98 Toyota Camry, when I drive it for about 30 minutes both radiator hoses expand and seems like they want to burst.I removed the thermostat but still acting the same. Seems like the car is building a lot of pressure from the engine.. What could this be? Already replaced the water pump and have a new. radiator... The car does not overheat with or without the thermostat.
View 6 RepliesI have a 1998 Camry V6 with 165000 miles. I had brake pads and rotors replaced on all four tires. Two days later, I noticed a flapping/knocking noise apparently coming from the rear of the car. It only happens after the car as been driving for 5-10 minutes. The noise increases in frequency as the speed of the vehicle increases and is unaffected by braking or bumps and gets louder the longer the car is driven. I took the car back and they re-checked all the brake installations and said everything was fine and the noise was nothing to worry about (of course I had to convince them that there really was a noise). They also said they inspected the tires and didn't find anything wrong. I have jacked the car up and looked under all tires and don't see anything close to the tires that could be hitting them. It sounds like a strip of rubber hitting a metal pan. I see no loose plastic guards or mudflaps. The tires were all replaced less than 2 years ago and they have been rotated regularly and visually appear to be in good shape.
View 4 RepliesI have a 1998 Toyota Camry , whenever I start it after its been sitting for 3 or more hours the rpm's shoot up to2,000 and stay there for 3-4 minutes straight, if I hit the gas they don't go down, if I turn my heat on they come down a little bit.
View 3 RepliesAfter about 10-15 minutes, following a cold start, this 2007 BMW X3 3.0 six does the following:
1) automatic cabin fan behaves erratically, jumping back and forth between low and high speeds;
2) cabin air does not heat;
3) electric radiator fans run on high;
4) coolant temp rises to normal, but then will suddenly jump up to full hot.
At this point, driver of course pulls over and shuts off engine. The amazing part is this: the engine can be re-started IMMEDIATELY and all of the above problems vanish instantly. Radiator fans shut off, temp returns to normal, cabin fan works normally, and cabin heat comes on. I'm thinking sticking thermostat, but why does shutting off the car momentarily fix it? Change of water pressure when coolant pump stops running?
I'm wanting to know if the hoses are the same?
i assume they are but never seen the under hood of a 10.5.
I drive a 2002 Ford Ranger and am wondering at what mileage should I change the heater and radiator hoses. The truck lives in Phoenix, AZ and is driven almost daily.
View 5 RepliesOn my 92 Aero 4.0L with A/C, I need to replace the radiator but I am not sure how to move the A/C hoses out of the way to extract the shroud and the radiator.
I have viewed a video where a guy said to remove the serpentine belt and then unbolt the A/C compressor and move the compressor and hoses out of the way. Hope this means that I don't have to discharge or disconnect AC hoses. Not good for me.....
Well, the video instruction seems simple enough......but there doesn't appear to be enough "play" in the AC hoses to move them far enough to extract the radiator, and not being an AC guy (and the potential danger of releasing freon), I am at a loss.
How to move the AC hoses out of the way (without disconnecting the hoses or discharging the system) ....
Not to mention it would be great to find out what the torque specification is for tightening the AC compressor bolts for proper reassembly. And being the backyard mechanic I am, any drawings, details or diagrams that you can provide would be very useful.
BTW, I have looked in the forum for radiator removal information and none of the threads I read addressed moving the AC hoses (which of course run right over the top of the dang radiator).
If I get past these "hoses" I will also take advantage of the radiator removal to replace the fan and fan clutch and thermostat while I am there, but first things first, if you know what I mean.
In April I replaced the radiator, hoses, water pump and Tstat. I used Mishimoto for the radiator and hoses (silicon). I am having trouble with the hoses leaking where they clamp to the radiator. I put 2 on the lower hose and that seemed to work. No other signs of leak on than drip from the top hose - factory clamp is on and tight as I can turn it - still lost a gallon in 2-3mo. Should I just get a new clamp? OEM stuff was not this prone to leaking ....
View 14 RepliesOk I have a 97 f150 4.6L. My radiator has been bad for a while. With brown rust color. I replaced my radiator, thermostat, new upper and lower hoses. Everything runs great but I have no heat. I flushed everything including the heater core. Core is not leaking into cab, and both heater hoses are cold. What should I do next FYI heat worked great until 5 days ago.
View 14 RepliesI start the car, with AC on, radiator fan starts and within a few minutes the engine radiator fan stops working, idles rough since the AC compressor pump keeps cycling on and off and engine starts to overheat. After shutting down I check the engine cooling fan fuse and it sure enough is blown.
How do I determine as to where the short is? Is the short in the wiring somewhere or can the actual motor short out?
2006 Toyota Camry LE (4 cyl) with 149,500 miles. All maintenance up to date.
Over the past month, anytime I drive over 80 mph within 15 minutes, the CEL comes on with the code P0420. I read the code and erase it. The funny thing is typically I'm getting very good gas mileage during that tankful when the CEL comes on. I've read that it is likely the downstream oxygen sensor and I plan to replace it. (In February, I replaced the air/fuel sensor). My two questions are:
a) What is the part number for the oxygen sensor (non-California emissions)? I want to make sure I get the right part.
b) Why the CEL comes on after travel over 80 mph? Is this coincidence or is there a reason why this happens?
I have a 76 f250/460 engine. I have replaced the hoses, belts, water pump, fan clutch, flowed the radiator and it still overheats.
View 4 RepliesWas just looking under the hood of the 08 R32 I just bought and noticed that a couple of smaller diameter (thumb size) hoses at the windshield had chew marks on it. Took it to my local shop. The mechanic called me a little later and said that there are actually 3 hoses chewed up, a third is down below, and that there is a nationwide back order on all three of these hoses with no estimate of when new hoses will arrive and it is unlikely that any dealer has these in stock. My mechanic said that he's been around long enough to know that when he sees a situation like this, there will likely be a recall on these hoses.
My mechanic said my hoses are pretty chewed up and the car is unsafe to drive, certainly not for long drives in hot weather. I am taking the car to a race shop nearby to install my Milltek exhaust and they have some ability to custom make hoses. I hope they can do it.
My son's 98 Expedition has no heat. The radiator and overflow tank are full, there's no air in the system. The radiator hoses get nice and hot but the heater hoses stay cold. We can hear the flow through the vents change when we change the temp control so I'm sure the blend door works fine. Seems like the problem is that no hot coolant is making it to the heater core. So I'm wondering if there is a diverter valve somewhere that could be bad that's keeping the hot coolant away from the HC or if a clogged HC is the only thing that could cause this.
View 1 RepliesFiguring out automatic shifter problem, the car only has 56k miles & it has problem (since 30k miles) shifting out of Park or stuck in Park, often I had to use the mechanical override to release it so I can put it in Neutral to start the engine. When placed in Drive, it kind of "floats," does not have the normal confident in-the-gear feel & sometimes it slips out of Drive to Neutral with the slightest bump of the gear shifter when driving or when stopped. When I shift, it does not have a free easy movement, it feels like the cable is restricted by corrosion or dirt, but everything looked good & seem shielded. Took it to a shop & they suggested that I just drive it... I've since put over 20k miles & its getting worse at finding Neutral to start the car with.
View 2 RepliesOver the last few weeks, I'd been smelling something. Today, I realized it must have been coolant. Today, my 225,000 mile, 2.3L 4cyl 5spd 1990 Camry started blowing smoke. When I parked, and gingerly touched the radiator, it was cool -- and empty. When I squeezed the upper hose, it crackled as if very dry. I drove the car about a mile and parked it at home.
When it cooled, I confirmed the radiator is empty -- except for a lot of reddish crud. A hint of the same reddish color on other engine parts MAY be from coolant spraying under the hood, but I'm not sure.
I couldn't tell from spots on the garage floor whether the coolant had leaked out there or not.
How should I proceed from here to address ... a) the leak, and b) any other damage caused by running the car dry?
I have 170,000 miles on this car. This is a 4 cylinder. The seam at the top of the radiator has cracked, causing a small leak. I have confirmed it is not leaking from the cap if you are curious. So it's time to replace the radiator. My question is: is the radiator easy to replace? I have worked on my car before with basic maintenance (oil, transmission, etc) I was thinking it would be straightforward to replace the radiator myself.
View 7 RepliesI have a 93 Camry that quit on the highway. No spark, crack in condensor replaced distributer. Still not run. Rotor not turning, replaced timing belt, main engine fuse heating up replaced that. Now it starts right up but only runs 10 minutes. Then won't restart until several hours go by then it will start again. Runs like a champ when it starts.
View 1 RepliesA140E transaxle issue... I have what I surmise is a direct clutch engagement issue. It takes (literally) 3 or MINUTES to engage reverse. And obviously the 2 -3 shift is slow also. It acts like there is a restriction in the passage to the direct piston. I rebuilt about 5 years ago, so am familiar with the teardown.
View 2 Replies92 Toyota Pickup (22RE auto). New block, rebuilt head, new water pump at 300k about a year ago. Sounds strange I know but that's what seems to have happened. Ive never been able to get heat from the truck since Ive owned it so Ive been trying to fix that. I flushed the coolant out and replaced the tstat. I brought the car to a mechanic and he put a pressure tester on the cooling system and he said it wasn't holding any pressure. He also pulled off the heater core inlet hose with the truck running and no coolant was coming out. He thought there was a blockage somewhere but how to fix it. I figured I might as well try replacing the old radiator cap with a new one so I did. Once I did this, the first time the truck went out, it overheated and the radiator crimped upper seam (on the plastic) burst outward.So all in all...something is wrong.
View 2 RepliesThis is Toyota Camry 98 with V6 3.0 engine.After smelling burnt oil while driving (mostly during stops, to be more precise), I took the car to Toyota service mechanics. They found leaks in both valve cover gaskets, and a leak from behind the timing belt cover. The leaks from valve covers were dripping onto exhaust, causing the burning smell.
The total repair cost is quoted at around $2k ($700 for valve covers and $1300 for what is behind the timing belt assembly).
Is it worth doing ? My worry is that, since 3 separate seals are failing, it is likely that other seals will start failing soon.Should the whole engine be rebuilt instead ?
