Urgent Help Needed! What's wrong with my bloody V8!!

[needfordspeed]

Hey guys,

Yet another problem with the EB, but I need urgent help because it's going in for the RW today and I need it fixed ASAP, so I don't have to re-book it and waste my time again. That's why it's here, and not in TECH!

The temp gauge keeps going up and up and up when you drive it around, then when you rev it high, it comes right down to normal again. I thought the new radiator could be blocked or something so I changed it back, still the same.

Nothing else was changed in the cooling system, just radiator and overflow, so what could have gone out?

I've just pulled the thermostat out and put it in boiling water and it didn't open. It's a 82 degree one, and I read somewhere when I was like 12 that if you put it in boiling water it should open.

Doug just threw that theory out the window, he reckons it needs water pressure to open!! Ideas, opinions!??

What a HEAP OF JUNK!!! I'm gunna have a nervous breakdown.

What about the water pump prop? If the coolant condition was bad mabey it stuffed it up. Might of lost a few fins.

[Gubas]

Also, mabey try running the car without a thermostat from a cold start

EDIT : Just figured it out Sunny, needs a turbo. Mabey 2. ;)

FFS...Take it to a mechanic. You said you would have a crack yourself, you have, didn't work; just give in!

I think it should open in boiling water. The spring should contract at the rating of the thermostat but that doesnt explain it getting better with more revs.

Water pump?

Just rev it heaps. She'll be right.

Is that heaps of revs on the spot or while driving?

If its while driving the air could be cooling it enough. Did you fix the thermofans? Are they AU ones and facing the right direction?

[MacGyver]

Thermostat will open in boiling water. If it doesn't open it is stuffed. If you just boil the kettle then pour some water on the thermostat the water may have cooled enough not to open. Best test is pot on stove with thermostat in it. It should open just before water starts to boil.

The thermostat doesn't need pressure to open. Like everyone else has said, put it in a saucepan full of water on the stove. Or you could replace it anyway. The genuine Ford ones are probably the best, they have the extra hole drilled in them already, and cost less than $20 from Ford.

Cool man, I'll keep that in mind next time I want to spend $60/hour in labour and then have a mechanic cane my car.

Me and Gill ended up figuring it out. It was a combination of a dud thermostat and air in the system. Fixed it all up, and it's sweet.

Saved $120 there by not taking it to a mechanic, and $30 he would have charged for a thermostat. Got a brand newy for $13+$2 for a gasket.

Question #2: Apparently you can get K-Frame end castor bushes for EA-ED that are 2 piece Urethane and don't have to be pressed in. Does anybody know of these or have tried these?

RW went OK, but there are a few things that popped up out of the blue.

Whats on the list Sundeep?

[Rollin]

Yeah I have the two piece bushes on my car - I redid the whole front end using k-mac stuff and didnt have to press anything in, they are all two piece, and come with grease as well.

I also agree with Gubas' edit in his second post

nah mate the thermostat opens by heat not pressure put on it and it should open easy as in boiling water but u fixed it anyway.

[Damo]

you should have taken it to a mechanic you hack. :P

What does it need for RWC ? Did you get the trailing arms sorted out ?

[needfordspeed]

Trailing arms were sorted out, took them to pedders in FTG and they pressed em in for $11!

Try taking out the thermostat again this time grab 1/8 " drill bit and drill 2 or 3 holes around the flat of the thermostat it allows minimal flow without effecting cold running see how that goesmaybe also radiator core may have a few blocked tubes so give it a good reverse flush and refill with only mixed coolant not straight water that is the worst thing you can do for alloy heads...ian

[Aaron_EF8]

Ford released a bulletin some time ago saying to do this to all E-Series thermostats, if you buy a genuine Ford thermostat, they have an extra hole drilled into them. It stops the hot coolant from shock loading the radiator when the thermostat opens, which causes the core and side tanks to weaken.
