water pump

since sorting the aircon out the temp guage has fluctuated a little. it also co incides with the battery causing issues. ive ordered a pump, new one to replace as a first measure.

question is:

who thinks this will sort it???

50p says you got it right as a first guess

I'll get Ladbrokes to open another book!!

...had you considered a compression test to see why the water pump has gone?

its the anti spasmodic thrutcher valve,as anybody who mends p38s knows.:doh:

its not a compression problem!!! well it better feckin not be!

so what its got water flow issues?Mine did that still after fittin a new water pump and it turned out to be a creased gasket in a water canal.Blew head gasket and water was dodget.Compression test will be a good start.

If cylinder pressure is leaking into water system it will over pressure that system PDQ and would be self evident. Why the compression test?

Mines a diesel, but the water temperature fluctuates a little with the aircon on. Considering how hot the condensor gets it's not surprising. On all my previous 4 X 4's the electric fans came on as soon as the aircon was switched on and the engine was up to temperature to assist the engine fan with the cooling, the P38 electric fans come on only rarely hence the temperature fluctuation.

If the engine radiator was put in front of the condenser, there would be loads of posts "Why are my electric fans running all the time!!!"

it only reared it head after aircon was gassed!

With the aircon running your bound to have warmer air passing through the radiator as the aircon condenser has pre heated it. If the gauge is not goung too high then it will be o.k.

the pump did have a tiny leak tho if you remember so i'd rather swap it(and the fact ive ordered it already) i just need a way of testing the sircon fan system is running ok, when the aircon is on the temp goes up but the fans dont kick in, then the book comes on and goes off when ignition off then on????

its a pain this car! i would just love it to work properly for one day!!!

When you see the temperature rise, switch the air con off and see if the temperature falls, if it does it would be reasonable to assume that the temperature rise is due, as Irish say's, to the pre-heated air from the condensor going through the engine rad.

The whole cooling system seem to be marginal in it's ability to cool the engines sufficiently, especially on the V8.

As soon as I'm a little less busy with the holiday season, I intend to modify the condensor electric cooling fan circuitry so that they operate both from the existing aircon control circuits and in addition from engine temperature via an adjustable thermostatic switch on the engine coolant top hose.

With my diesel, in hot weather (30C or more) on uphill drags, I can either tow the caravan or have airconditioning on. If I do both the engine temperature starts to rise long before the fans cut in which worries me.

mines the same but without a caravan!!! last night red light cam on and i only had the bloody window program on!!!

Bloody hell:doh::doh::doh:

thats why a new pump is on order and possibly a new rad!

How much for the pump?

cost me about 40 quid i think!
