This is an awkward job. Remove air box out of way, now there's two ways to approach this, you can remove exhaust cross tube not recomended or you can use socket,universal and extension and try to remove the bolts from under the exhaust cross tube. I know it's probably not what you want to hear but its the only way with out making a mountain out of a mole hill, hope this helps.

Leaky valve cover on my jdm subaru


The only thing you might need to buy beside the gasket is any rubber parts that have been damaged by the leaking oil.
Check your radiator hoses, heater hoses, and vacuum lines, because motor oil will "rot:" rubber.
You need only replace hoses that are "spongy"and are wet with oil.
Be blessed.

Thermostat pipe is leaking land rover freelander 2001 td 4


Your question is not very clear, but I will do my best to help you. The hose that connects to the thermostat on the engine block could be leaking or the thermostat housing (inside it is the thermostat) has a leaky gasket. Either way, change out the hose or the gasket!

I think i have located the thermostat but there is something mounted about it that would have to be unbolted in order to get to the thermostat, does anyone know what this is and if i can get to the...


You state that you think you have located the thermostat. The part that will need to be unbolted and removed is the thermostat housing. Simply remove the radiator hose and remove the bolts holding the housing in place. You may need to tap the housing gently to break it loose. The thermostat is located in the housing. Be sure to carefully scrap off any remaining gasket on the thermostat housing and the engine where the housing sits. Replace the thermostat and install a new gasket, replace housing, tighten bolts evenly and reattach radiator hose. Top off the radiator to replace any lost coolant.

Need to replace thermostat housing in a 2000 pontiac grand am 2.4L. I know where it is but I need to know about any precautions and what is involved in the process,


Engine should be cool

Catch leaking anti-freeze from thermostat housing hose when disconnected (if any)

Good idea to always disconnect negative battery cable anytime working under hood for extended period

Clean old gasket of block

These come to mind.

Leak near the gasget on my van


Its always a good idea to replace the thermostat housing every few years as they warp,if you dont have the extra cash you can remove the leaky one,and put the new thermostat in the block put a thin layer of good silicone around the stat,take another thin layer and apply it to the housing then you really dont need a gasket but you can still use one with this method,replacing the old bolts is a good idea also and that way you can tighten them correctly with no fear.have a good day DB
