!!!!!!!!!!!!!!!!Overheating!!!!!!!!!!!!!!!!!!

[oldone]

Rix, I think you are the right path ...IF you know its not a motor problem ..then you have to start eliminationg the auxilaries one by one....The reason i say this is...when you are moving and you have air flow through the radiator then the temps are normal.Once you stop and you rely on the auxliaries to keep all cool..then you have the prob.Step back for a while from the car and think with basic logic about the cooling of the car.That way it is easier for you to eliminate probs..........:Typing  Wish I was closer to you so I could try and help...hate to anybody struggle !!!!!!!!!!!

Im gona order a low temp thermostat aswell as the Air Pump removal kit & AC Pump removal kit on Tuesday. Hopefully get a water pump from Shaun & try and do it all next weekend...im gona go see if i can find the boost problem now though...:Hammer

Anything else i should be check/looking for?

Just a thought about this, maybe all the problems are being caused by the thermostat, have you put a new one in yet ? Its only a cheap replacement and 3 bolts !!!!!!

Shaun

have you checked temp sensors for fans yet? mine never went above 98\' because the fans came in.
also have you checked the water pump as it sounds as though the water isnt moving around properly.

Where swapping it over next weekend hopefully. I hope the waterpump is the problem !

Rust in the water is not a good sign, have you been running Inhibitor with the coolant?

I have had all sorts of water seal Problems in the past and its better to have the Block presure tested to check for Leaks rather than checking the coolant, this is mainly becouse when it overheats you loose all the coolant and so you don\'t get a good reading.

Plate Water seal groove failure is getting very common and depending on where the Groove fails it can give diffrent symptoms some more Dramatic than others.

8K seems a LOT of money for a rebuild what else did you have done at the same time?

hopefully, i had the same prob on an old escort and that fixed it and an old citron and waterpump was the only thing not replaced.

I was just thinking, If it was the Water pump thats to blame if you remove the Pulley from the front there will be water marks from the lower drain hole.

When it\'s hot/overheating can you actually hear the fans operating?

[Rixio]

The fans are always on...as soon as the ingnition is on the fans are on. They have been wired up like that before i had the car...so they dont kick in at 85\'c they are just constantly on...??!?!??:2eek

£8k gets you a New Clutch, Cleaned & Tested Injectors, New Turbos, Street Porting, New 3" Downpipe, Uprated HT Leads, New Plugs, Full rebuild, Power FC + Commander (even though i dont have the commander still + had to buy a seperate one!) Mapping & other stuff done aswell but cant remember the rest :Hammer

Could it be that the belts are slack?
Like Shaun said, hopefully its the water pump and it\'l be sorted by the weekend...Fingers crossed
Although i have been advised by Carl & Clive that it also could be a blockage in the rad. So if any of you guyz have a spare rad that they dont mind letting me borrow to check, can you shoot me a PM please. Any help would be greatly appreciated

This could be your problem or part of it, the fans have 4 speeds normally...maybe yours are running at the lowest speed which is insufficient to cope with high temps and traffic.

Get them checked out mate :cheers

i have a series 1, i know there a different beast but i had overheating problems, to be honest is was the other way round overheating at 90mph and fine in traffic, nearly ripped out my from grill, new fan then rad, ordered a new fan belt from Mazda as the one i had was not the sold v one, changed the belt and solved the problem!, just ordered a double pulley for the alternator as mine only runs a single belt since the air pump went, do you have overdrive pulleys?

Mark

[Rixio]

The Belts are all stock atm i was intending to take the air pump and ac pump out this weekend whilst changing the water pump...but have been advised that it slows down the water pump

This sounds like a good idea to me.  When my temps get into high 90s in traffic i press the Aircon button (aircon removed) and the fans step up a gear and coll engine down, have you tried that?  Do you have another rex you can look at to check the wiring against, i\'m not too far away if you get stuck.

Cheers
