Question about Cars & Trucks

2 Answers

I have a 94 camaro v6 3.4 and I just replaced my radiator, temp sensor, and thermostat. When I was burping the system a leak showed up in one of the lines coming from the heater control valve. I've been having a hell of a time trying to find out what those lines are to replace them. I say them because it's like a junction of three lines that meet and go into the valve. Would anyone know what I could do to replace them? Or if anyone knows just what they're called?

If it's a hose you're looking for, the local auto parts store will carry them, custom molded, or you can buy the straight hose by the foot.
the parts counter will have pictures to look at to id the correct hose. While you're in there, the heater control valve is especially unreliable if plastic, and should be swapped with any old hoses. Buy a metal one if you can get one.I have a 94 camaro v6 3.4 and I just replaced my - 25316245-dz1fkxf1fwolart5ai0divhk-5-0.jpg

They're called heater hoses and are available online practically anywhere. I had a Z34 3.4 Lumina same unit same problem. I hated the 3.4 but I was the only one in England with one. Watch out for alternator problems. They come as whole units of rubber and metal in a pair. any good ?

    Found out it's a heater hose inlet pipe that I'm looking for. The downside is that that specific design was discontinued.

    Ebay will have parts...they had everything I needed, some real odd parts. There are many many discontinued parts around, still in their boxes....check out jeff5's answer above. you are not in a deep hole ! good luck Red.

    GM discontinued that rig because it is a fail. The whole hose and valve rig is available as a retrofit kit from your friendly GM dealer. It isn't a recall item, though. Ask any experienced chevy mechanic, the quad 4 engines all have the strange heater plumbing and the digital egr valve that fail over and over every few years unless they are retrofitted.

    the v6 engines also have leaky plastic intakes with wonky seals and gaskets, if you have a mystery coolant leak, they are also superseded.

Replace the low coolant sensor right side if radiator. When you replaced the radiator
they may have installed the old sensor.

I had the same problem.

SOURCE: one heater hose is hotter than the other heater

It sounds like you have a plugged or clogged heater core. If the heater control valve was bad, both hoses would be hot, or cool.

Will an air pocket in the coolant system cause it to overheat or over pressurize on a 2001 Nissan Sentra ?

1. The radiator cap if working correctly it will release pressure in the system provided the cap you have is the correct pressure setting. If you are having a problem with pressure then replace the cap with a new radiator cap with the correct pressure setting. Do not use a cap with a pressure setting other than the original equipment pressure spec. So you do not go to the parts store and buy any radiator cap on the shelf that fits because they come with different pressure ratings and some of these will be totally unsuitable for your car.

2. If the pressure valve is stuck in the "old" cap the pressure release system will not work.

3. Overheating
Air pockets in the cooling system can definitely cause overheating and can retard coolant flow through the system. If you are draining the radiator to replace the coolant or replacing the radiator you need to follow the correct procedures for bleeding air out of the system for that particular engine after coolant refilling. Some engines have bleeder screws on the cooling system to assist in the air bleeding procedure and some don't.

There are various causes for overheating so don't assume it will necessarily be solved by bleeding any remaining air from the cooling system and replacing the radiator cap with one that works.

Other causes can be...........
1. Faulty cooling system thermostat. (Replace the Thermostat)
2. Faulty water pump, especially if the impellers have corroded away or have disintegrated in the case of those design genius water pumps with plastic impellers. (Replace the water pump)

3. Cooling fans not working and if so the cause needs to be tracked. Check that your fans are kicking in. If the engine is overheating the fans should be running because they will switch on when the coolant reaches a specific temp and well before the coolant gets excessively hot.

4. A partial blockage in the coolant passages inside the engine but not in the radiator if you have a new one. If the coolant is not changed at the required intervals(frequently the case with many owners) or is over diluted with water you can get a build up of debris. If products like stop leak have been used in the system this can create similar problems with partial blockages inside the engine coolant passages.

5. A compression leak into the cooling system.
If you have bled air from the system and have continuous air bubbles in the cooling system I would suspect a compression leak. In that event a basic leak down test will show if you have compression gasses leaking into the cooling system and from which cylinder(s). The spark plug is removed and compressed air is forced into the cylinder via the spark plug fitting and air bubbles will show up in the coolant of there is a leak into the cooling system.
Have the problem with overheating addressed immediately. Running the engine with an overheat condition will cause expensive engine damage many times the cost of fixing the overheating issue.

Why does my 2001 mitsubishi galant over heat still after I replaced the radiator and replaced the heater core?

Have a 96 Buick Park Ave. In Aug I changed the thermostat because the temp gauge showed the motor was running cold. nothing changed. In Sept I had the water pump replaced because it started leaking. M

Is your 3800 producing normal heat? If so, the temp sensor is probably bad...If not, try replacing the radiator cap...if your system has air trapped inside, it usually runs hot, not cold...the heat is the key to functioning properly for you...Your radiator is a 4 stage huge system that normally cools very well...if you have heat, I still think your temp sensor is bad...ask to see one at your parts store, will help you to locate it. Hope this helps.

Does ford 3.8 v 6 temp sensore thread into water jacket?

maybe air in the system? park it on ramps or a good uphill slant and remove the radiator cap and let it burp while you refill the radiator with coolant

Coolant temperature fluctuates

What you are describing is a cooling system low on coolant or a sticking thermostat.
I might leave the thermostat out and drive it a few days to see what happens. There could be something in the system that is restricting flow, or it could still be low on coolant.
Its possible something is not right with air flow thru the radiator or the fan clutch. There could be a restriction in the ac condenser.

2003 honda civic ex overheating. I have replaced the waterpump, radiator and thermostat. car is still overheating. I have followed all repair manual directions. what else am I missing????? sensor bad???...

Replaced the temp sensor? "Burped" the system? Sure the thermostat is in the right way? You can even try running without the thermostat to see if that helps.

1995 Z28 overheating and loosing power

It sounds like your cooling system is becoming clogged with debris. Flush your radiator, replace the temperature sensor and the thermostat. Also, Griffin makes great after market high capacity aluminum radiators, a little pricey, but worth the money the event you have to replace the radiator due leaks and corrosion.

Radiator fan for 2001 Jeep Cherokee

Had this problem and one thing that even Chilton manuals only show in fine print sorta say is that Jeep cherokee has a relay sensor for the coolant fan usualy right behind the passenger or driver side headlight you may have to remove the bumper also its rather easy.Its a liitle black box thats screwd down on the panel just unscrew it unplug it replace mine ran me around $60.00.Before I learned about this after replacing the thermostate and just about to rip out the water pump my buddy told me about the sensor after replacing over a year ago no problems.
