I am a pessimist because the odds are far better then an optimist.

Big jeeps commonly run in hot climates that we dint see in the UK. They also manage to do it without odd bonnets or formula 1 ducting in the engine bay. There are also plenty of other square shaped trucks that are lifted or lowered that run even bigger horse power without issues.

You have had the same issue with both engines and changed everything except the rad. That only leaves one item in my eyes.

If you are so close to curing the issue by moving or modifying the bonnet you will just do something else. Drive faster, fill the truck with all the kids, manage to find the biggest and longest hill or tow a trailer and you will be calling the AA again.

Here's an idea......

FSJ hoods are held on by the hinge/spring mech on the inside....... 4 bolts to hold hood onto the mechanism?.
I'm guessing here FSJ Birtys advise

Take one of those bolts out and get 4 tomorrow that are 30mm longer.......then I have got 4 stainless circular  30mm spacers that were seat risers that are looking for a home and are sitting idly on my workbench.

There you go instant 30mm air escape gap at rear of hood that you can do the motorway test on......
Shout if of interest.....

Just a shame there on studs!  But get the stud out and replace with a longer bolt...

And the 360 overheated because the rad was just a big block of mud with water running through it. This problem I think is different.

[Bulldog67]

I have contacted some US sellers of fancy rads to see if they will ship - waiting in answers

I have done what feels like everything else so in the long run its not gonna do any harm ........

The original rad was new by the PO but who knows whether he got mugged

I'm figuring next wallet pillaging may as well involve throwing the kitchen sink at it

[wildwood]

Don't forget the 'Pirate sourced formula' of cubic inches to square inches of rad.......

I know we've done this before but just in case


a 401 engine needs 401 + square inches of rad..... And that is just the element not including the tanks top and bottom or preferably left and right if it's a cross flow....... And ally cools better than
Old school brass......

And then if you can get multicore thickness then even better........ And so the mystical cooling mantra goes on and on.......
I am sure we.....(you) will get there in  the end.........

[demonicwillow]

Have you removed the rad, filled it totally with water, emptied that water into a bucket measuring device, then dimensioned the rad to see if your getting roughly its water capacity into it, also if your rad is approximately the right size have you thought about getting it re-corred ?? maybe worth going to your local rad repair shop for advice with it.

Can you post a pic or pics of your engine bay which shows the rad position ??

So why do the yanks fit a standard 2 core stock rad the same as a 4.2 six?

[Bubba]

 

in my fsj days i found and swapped the same rad regardless of engine

[xr6jeeper]

Sounds daft but are the fans turning in the right direction,

[Bulldog67]

Right, decision made - its heading back up north to Jim and not allowed back to the glamorous south until its learnt to behave itself


Only good bit of tyres being nicked was finding out that there is a helluva lot of love for the bastard thing - landy owners etc in kent telling me they drive past my house just to look at etc, its more famous than i realised and even local non 4x4 doods from my estate knocking on my door to give condolences etc as its such a 'beautiful beast' etc so that has given me a kick up the arse to get it sorted once and for all ( )

Silver linings doods, silver linings

Watched my dad live a v frugal life (& inflict it on me) so he could have a comfortable retirement and tbe poor old sod is wealthy but also to ill to do fuck all worthwhile. Im getting to that age where i hear bout people i know of my age gettin cancer and heart attacks etc so im following the plan of spend it while ya got it coz ya could be dead next week!!!

The mystery of alternator belts disappearing has bern solved ........... by me

Rogue jubilee clip badly placed amd was cutting thru the belt.


So new belts fitted and transporter booked - new tyres not going on until the night b4 tho

[j33pky]

Mechanic of the year goes to........... Bullfrog

[Bulldog67]

 

[Bulldog67]

Only took me 3 shredded belts and trip home with the AA to find out why

[5536paulj]

Ade,
Trans cooler has sorted my issues, and I have similar drivetrain to you....

Fluid goes through the in rad cooler first, then to the new one in front of the rad and then back to the th400, runs cool now.

Just trying to help

PJ

[Bulldog67]

cheers buddy, appreciate that - and damn good news for you

fuck I hope it fixes mine

I will inform Mr Sunderland when I see him on Saturday

[5536paulj]

If I was you, ,given the size of the vehicle and your enthusiastic driving style (!) I'd use an engine driven fan with shroud, which will always give the most airflow, with a big trans cooler in front of the rad, the B and M one I got is nice as it bypasses when the trans is cool so won't over cool the th400, came with all the right fittings too, even i could fit it in a couple of hours..

Good Luck

Old thread now but for all you "temperature sensor should be in the top hose not bottom hose" back seat mechanics, i think we all owe Mr Sunderland an apology........

 

[isle of man]

Heat rises !! The Mafia has it on the top hose.

[Bulldog67]

Its not exactly an old thread as the beast still lusts after heat and so the thread will need an update soon enough but good to know its in safe hands 

[Bulldog67]

and although I never said it at the time I trawled the services of quite a few 'mechanics/garages' in the southern half of the country (was trying to avoid the transportation costs up to Jim) to see if they wanted to fault find the overheating on the Molotov and all said nope, not one was interested in any shape or form, despite them all coming from recommendations, however when I rang Jim and asked ... 'I dont suppose you would be interested in .....?' he replied yes without a milliseconds hesitation    responses like that go a long way in my book - so transport costs in the future will just be factored in regardless

[Dave69]

Heat rises !! The Mafia has it on the top hose.

Radiator cooling development is always done with the coolant temperature referenced from the top hose, this then combined with a measurement of the bottom hose allows engineers to work out the efficiency of the radiator. If a temperature is taken from the main block then a correction factor has to be used by the coolant control module or the temperature for the viscous fan requires changing to suit.

doesn't matter where you control sensor is, as long as it switches on the cooling fan for a inlet temperature of circa 90 to 95 degC (or lower if required)

Are you some sort of kiss ass?  even if he is right you don't tell him
