big problems me thinks

[hollowlegs]

unfortunatly it seems i have run out of idea's to fix the overheating problem im having with my t350,

so far have blown two radiators, changed water temp sensor, thermostat and bought and fitted the second expansion tank kit and new blue cap.

still seeming to get it climbing to high tempratures quickly and theres no signs of any fans coming on right upto 110'c when turning the thing off. so have also checked the fuses and relay's which are fine

took it to get pressure tested and found 3 leaks from hoses, fitted new jubillee clips and tried again but still no change,

if anyone has any other idea's as to what i could try fire them up but i have a sneaking suspision that i may have a head gasket problem.

the car is booked into dreadnaught tvr up here in scotland next week to get checked over but if the engine will be out i fancy getting some upgrades done, its a 53 plate with 13,000 miles, any recomendations as to where and what parts i should go for?

been off the road 3 weeks already and boy do i miss driving it!

cheers guys

Sounds like your fan switch is faulty. I had it happen on my 05 T350, fan switch failed, the fans never kicked in, which ended up boiling the fluids.

Get the dealer to replace the switch.

The fan switch is NOT the same as the temperature sender (that is for information only). It does sound like the fan switches are faulty.
I realy wish I could get a wiring diagram for a t350.

i suppose it could be but the car was heating up quite quickly, im convinced theres something worse as i didnt think the fans could make a huge differance cutting in at 96'c and 98'c, in my eyes thats too late as its already boiling

just hacked off now and getting the dealer to fix it.

it needs to go in to get the drivers door catch fixed aswell and want the tappets etc checked for piece of mind as iv not owned it long and unsure how the previous owner might have treated it.

98 is not boiling, if you have decent coolant you should be able to see 110 without the thing boiling. On my t350 05reg last summer, was a bad connection and just letting it go above 105 without the fans made it hard to keep it cool afterwards. Get the fans soughted and I think you will find a big difference.

Mine boiled over a couple of years ago - the temperature went to 115oC in the course of just a couple of minutes. I managed to stop (I was in heavy traffic on a choked up dual carriageway in the centre of Sheffield) just in time to let the fluids boil away out of the pressure cap. The problem? That bloody 50p fan relay that, when it goes, results in thousnads of pounds worth of damage. Except it didn't in mine

Sounds very much like what's happening with yours.

[hollowlegs]

yep rich (yhm) hopefully it'll be sorted tomorrow if the new switch arrives from dream machines, have been speaking to them about the car for the last week or two and richard the parts man is very helpful and always been able to get parts up to me within a day or two!

will go have a looky at the current one as the fans have never seemed to come much since buying the car, just a flicker now and again, they even spun up yesterday then stopped, at around 50'c,

my head hurts.

[munichtamora]

Did you get this problem fixed ? What was it ?

[hollowlegs]

SUPERB! recieved the fan switch today and just fitted, fans kicking in mid ninety's and keeping her cool. the temp sat between 90 and 96 most of the time with the occasional flicker to 97/98'c although it is a hot day it seems fine, prob still a wee bit of air kicking about in it to bleed out.

bit annoyed that it turned out to be a £13.85 part which has caused this, now i can get back to enjoying the rest of my 'honeymoon' period.

thanks for the pointers guys

Question. If you leave the cap to the petrol tank open by mistake and drive for a while - will it draw air into the engine? which can then lead to over heating? I did exactly just that and for the first time my car hit 102 (oil) although for just a split second on the Kings road last night. It's now hovering in the mid 90's around town. If there is air that needs 'bleeding' from the engine, how do I go about doing this?

Thanks

No. Its just sealed for the emissions system to be fully compliant. Some people say it should be left loose, others tight. The fuel pump takes fuel at the bottom of the tank - it won't suck air unless the tank is empty.

Good to know. Thanks.
