You would really need to replace the plastic intake. they are not cheap, but any other "fix it" would only be temporary...

2.3L and 2.4L Engines
(see Figure 7)

When adding coolant, it is important that you use GM Goodwrench DEX-COOL® (orange colored, silicate free) coolant meeting GM specifications. On these vehicles, if silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner; at 30,000 milee or 24 months.
  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant to a level below the thermostat.
  3. Unfasten the cover-to-outlet pipe bolt, which is accessible through the exhaust manifold runners.
  4. Raise and safely support the vehicle.
  5. Disconnect the radiator and heater hoses from the outlet pipe.
  6. Unfasten the outlet pipe-to-oil pan bolt and the cover-to-outlet pipe bolts.
  7. Remove the thermostat, then clean the old gasket material from the mating surfaces.

I'm in the process of replacing the thermostat on my 2003 freelander. finally got the coolant drained......that was fun. everything is disconnected and all intake plenum bolts removed( 4 small in the...


You will have to remove the intake manifold (this is the solid large plastic cover that covers the top of the engine when you remove the engine cover). There are many wires and small vacuum hoses to disconnect. Plus.., when re-installing, it is a common problem the manifold cracks if excessive torque is applied to the fastening bolts. And you probably should relpace the intake manifold gasket.You can then remove the thermostat assembly by disconnecting the hoses and loosening the mounting screw.

----------

The procedure as per service manual is as follows:----

Following the Service Manual instructions, drain the coolant circuit, then remove the return pipe and the short rubber hose connected to the engine main coolant rail (1 clip at the bottom + 1 clip at the top). You remove also the outlet hose (1 clip at the engine outlet spout + 1 clip at the bottom pipe, you need to loosen the pipe mount to remove the hose). Once removed the return pipe you can undo the coolant rail: 2 (tight) bolts below the rail and the oil dipstick bolt holding the thermostat housing. Doing this without the manifold in place is simple, but its not that easy with the manifold on.... once loosened the coolant rail you can remove the thermostat housing. You open it (3 bolts) and replace the old thermostat with new. All 3 gaskets should be replaced, to minimize the risk of leaks. Apply silicone lubricant on the O-rings, then fit housing + coolant rail back in.

This will help you.Thanks.Helpmech.

How to replace the water pump on 1993 oldsmoblie achieva.


2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael

Intake manifold sealant repair now leaking maybe oil? coolant b4


You need to remove the thermostat housing again. Then you will have to extract the bolts you broke off. You will need to drill and tap them so you can use an easy out to remove the broken bolts from the threads. Then you can clean up both mating surfaces and replace the gasket and the thermostat. Check to make sure you did not crack the thermostat housing or you may have another leak when finished. They are usually aluminum and break easily if too much pressure is applied or they are corroded and weak.

1998 mustang gt coolant leak


I just had the same problem. Ford design the intake manifold with plastic water crossover which cracks. The coolant will leak onto the top of the block and and then down the back of the engine. This intake design is a known defect and was ocvered under by Ford for 7 years past the date of mfg. The crack either is in the crossover or the thermostat housing. I happed on this when I found the same leak and traced it back to the thermostat housing. I changed the thermostat, but it leaked worse. You can pickup a aftermarket for $200 and it's about 4-6 hr job to replace.
