Engine head changing head casket

The head gasket needs to be replaced. Have you checked the thermostat the cooling fan(s)?

water pump not working , does the coolant boilaway change waterpump , cracked head , check the cylinder compressions to check the head

before???? (2.5L , v6/) i have a 04 GV, 2.5L with full factory docs.
casket gasket, , it is close. when it blows to the casket .
no cranks
or now starts.
my guess, car wont start.
1 check all fuses in both boxes. EFI dont run with them blown,
2 check compression, if bad, 150psi on all, is normal, wide open throttle checked only.
if compression is good, the gasket is mostly good
there 2 more tests in this regard, 1: exh, in rad neck tester, and rad leak down tester) the exh, method sure can warn of early head gasket failures.
3: check for spark at all cylinders, not just 1 and check timing same.
4: ok engine will start now in test fuel for 3sec and die or run.
3sec. only means you lost fueling
runs, now means engine was flooded.
ever do the 60,000 mile tunup?

Casket, are you sure that is what you meant to write. No make not any model or year and no engine info. I guess you really don't want to get help with this?

you have to replace engine oil cooler . you can't test the oil engine cooler . try re tied cyl. heead bolts , make flash radiator ,and check. good luk

Sorry to be a bit indifferent here but a proper mechanic doesnt need a repair manual ,its a engine be it petrol or diesel and as such its basic mechanics to strip and repair which any competent trained mechanic should be able to do with or without a manual .

lots of possible causes?

Have you checked the oil?
Seen a LOT of cracked heads and/or caskets on this little engine

Not that tough but time consuming and a lot of things to remove. You need to buy you a Haynes repair manual or Mitchel manual at your parts store. They are written in laymen terms and easy to understand and they will give you the torque values to re-torque your head bolts once you get to that stage.
