I need to see a coolant system hose that leaks does the intake have to be removed

\015 Just had radiator flushed but coolant leaks. do i really have to remove intake to change some of the hoses?\015 Posted / edited by AnonymousUser on : 15-01-2018

Answers :

Yes there are cooling system hoses under the intake, here are instructions to remove the intake.

  1. Remove the Intake Manifold
    • 1Drain the cooling system and relieve the pressure in the fuel system. Disconnect the negative battery cable, the air intake duct, the IAC valve connectors, the throttle position sensor and switch connectors, and the EGR solenoid valve.
    • 2Pull the EVAP canister vacuum and purge hoses, the vacuum hoses from the EVAP, the brake cylinder, pressure regulator and EGR tube. Tag and disconnect the spark plug wires. Remove the distributor cap.
    • 3. Take out the three left bank injector connectors, the thermal transmitter, the ground harness, breather pipe and the upper manifold. Disconnect the fuel feed and return lines and plug them with golf tees to prevent fuel spillage.
    • 4Locate the right injector harness connectors and disconnect them as well as the fuel rail and injectors. Remove the coolant temperature switch harness connector and the water hose from the thermostat.
    • 5Loose the bolts on the lower manifold in sequence. Remove the bolts and left the intake manifold from the engine. Remove the gasket and discard it.
    • 6Clean the mating surfaces by scraping the old gasket material and carbon deposits. Clean the surfaces with solvent and inspect them for damage.
    Install the Intake Manifold
    • 7Put a new gasket in place and install the lower intake manifold to the engine. Tighten the bolts in sequence as follows: first pass-35 inch pounds; second pass-78 inch pounds and third pass 70 to 84 inch pounds.
    • 8Connect the ECT sensor connector, the fuel supply manifold and the right bank injector connectors. Connect the fuel lines and then install the upper intake manifold. Put the breather pipe in position.
    • 9Install the intake manifold ground cable, the thermal transmitter, the left bank injector connectors and the distributor. Reconnect the spark plug wires.
    • 10Continue reconnecting all the components, reversing the order in which they were removed. Connect the negative battery cable to the terminal. Refill the cooling system with the appropriate coolant.
    • 11Start the engine. Check for fuel or vacuum leaks.

Coolant leak I have a 2001 Focus (16v Zetec) and about every 2 weeks I need to add more coolant. I did have a hose leaking but it was replaced and I still have to add coolant. I have taken it to a local shop but they were unable to detect a leak. Prior to having the hose replaced I could see coolant on the ground but afterward I don't see any place where it's leaking but I continue to have to add coolant. Can you help?

Heating and cooling system leak under intake manifold. I cannot see the heater hoses without removing the intake manifold. What should I be looking for, this is a major leak.Thanks, Eric

You are not going to know for sure until you pull the manifold, but should be a easy fix, will be either the round welsh plugs, a corroded steel tube , or hose and clamp.\015\012With the manifold off, a pressure test will squirt the coolant out ... 1991 Toyota Pickup

I am Trying to determine what Parts I need to fix the leganza I will be buying off of my Aunt. But the Diagram of the cooling system shows up way too small.

Coolant leak Hi there does anyone out there know what causes my 1995 Grande Cherokee to leak coolant somewhere along the front of the intake manifold. I've replaced my water pump twice, my radiator, and all of my hoses. I've also had the system pressure tested for leaks. Is there a frost plug on the upper part of the engine at the front, or can the coolant be leaking at front of the intake manifold...??

Hi, I have a 97 Z-24 w the 2.4L and while searching for a mysterious coolant leak I removed the air intake tube which contains some sensor. I did this so I could see better. Well, I left that sensor unplugged and now I have a check engine light. I tried disconecting the battery, but that didnt clear it. Do I need a scanner to clear and what is this sensor anyway?

It will clear after 40 complete ignition cycles, or you can clear it with a scanner, it is the intake air temp sensor, it will not hurt anything if you ran it unplugged ... 1997 Chevrolet Cavalier

Vacuum leak I have an 05 chevy colorado 3.5 5cyl. I noticed a vacuum leak on the hose that goes from the valve cover to the intake manifold.Problem is that in order to fix the leak,the black plastic cover over the intake manifold needs to be removed or at least loosened.Any idea how this cover can be removed?

Mine is doing the same, it's your pcv receptor on the manifold. that hard plastic cover is actually part of the intake itself, if it "came off" it would cut your intake in half. that seem seals the two halfs together. you gotta pull the whole inta ... 2005 Chevrolet Colorado

Coolant leak I'm loosing coolant but can not see any leaks, i've checked hoses from engine to radiator, do not see any moister around the heads or intake manifold. Are there lines running to the back of the van for the rear heat? There is an odor of coolant when driving.

On these mini vans there are lines to back if it has temp control in back. How much water do you loose in what period of time? If no leaks found then check exhaust while running to see if coolant smell from there. Could have leak in gasket on intake ... 2004 Chrysler Town & Country

I have a 1994 toyota camry v6, today my car boiled all the coolant out of the reservoir tank. I had a problem with disapearing coolant a few months back. I flushed the system tightened all the hoses and add a stop leak to the cooling system and refilled with coolant, the car ran great for a while. I never let the car over heat I could always tell when it needed coolant when I would hear the fans working extra hard to keep the car cool and when I turn the heat on full blast the temp would fall.

Radiator Flush I have drained the radiator and need to know what do from here. Do I leave the valve open while the engine is running and keep water from the hose introducing fluid into the cooling system? Or should I be going about this differently?

Coolant leak I have the same problem; one of the rubber coolant hoses that disappersbehind the engine broke off wherever it is connected. From the pieceleft in the hose, there was a plastic connector inside the hose goingto whatever is behind the engine, and it finally degraded and broke off(1995 model). Please tell me I don't have to remove the engine to fix; i don't see any other way as there is no room to work.

I own a 2006 chevy 2500HD with a 6.0L gas engine. I need to do a coolant flush. Through lots of research I found the flush valve for coolant systems was discontinued by GM in 2003. There is still a valve on my radiator however it looks to be plugged. Before removing the radiator hose to do a reverse flush (no radiator cap only a surge tank) I need to drain coolant above that level. Is there a way to do this or do I use the surge tank cap as I would the actual radiator cap?

I need to remove the upper intake manifold from my 2004 dodge intrepid 2.7 l engine to replace the water outlet from coolant system. How do I remove and replace the manifold? Will I need a new gasket?

First off, you need to label all of the electrical and vacuum lines connecting to the intake manifold. This will make reassembly much easier. Then, there is a torque sequence to be used during disassembly and reassembly. ... 2004 Dodge Intrepid

I have a coolant leak somewhere under the turbo housing toward the block very hard to see i removed lower exhaust and shrouds around turbo to help see leak i notice a quarter inch hole in block just above cooling hoses that is very deep with no threads could that be a freeze plug?

No, under the turbo there is a cooling hose with a heat wrap around it that kind of looks like tin foil, that hose probably has a pinhole in it and needs to be changed, which is a difficult job (bad design). ... 1988 Subaru GL-10

1994 Grand Marquis (4.6L) leaking coolant. It drips from the front of the block under the harmonic balance. I need to remove the shroud so I can see the water pump which probably needs replacing. My manual says to remove the fan and then the shroud but there isn?t enough room between the shroud and the front of the engine to reach in and unbolt the fan. is there a better way? thanks in advance. ted

The fan unscrews without bolts. if you look between fan and pulley you wil see the big hex nut to unscrew. in other words it unscrews like a jar lid. p.s. it may be left hand thread it should say so on the shroud ... 1995 Mercury Grand Marquis

My Granddaughter has a 2003 Honda Civic which has started overheating and the coolant will be low. Can see no leaks. Happens after 2-3 weeks of driving.

I know my intake gaskets are leaking on my 97 lumina 3.1 , but I'am not sure the head gaskets are bad, could coolant get in the cylinders from this? I was going to pressure test the cooling system over night to see if coolant would fill a cylinder ? I wondered if the tester could make this happen and make me think head gaskets were bad? I guess I'am being lazy and don't want to do compression check 6 times.
