Need help with my T350c
Discussion
Hi
Im a T350c owner from sweden, and i was at the swedish registration last week and the fan didnt cut in a 95 degrees so the cooler sprayed up som water and we did unconnect the connection under the airbox so now the fans go all the time instead, should i do a own switch so i could put on the fans when i want too in the car? Does anyone have a site with the parts needed, i heard that its only a switch and two cables to the connection under the airbox. (i dont have any mechanical skills)
The fan problem did take some time at the car registration so we didnt do all the thing at the carregistration, and when i tried to start the engine later the car didnt start, the starter turned, but then it was to much petrol so i did take away the brown box for the fuel pump and then it started two times shortly so the petrol went out and then putted the brown box back and then it started, but i have done this all the time now, out with the brown box and then put in it and start with like 2000 revs. Do anyone know why it gets to much gas?
I did get the advice on how to do the fan and fuel pump from the best glasfiber guy (plastic man).
The things that the carregistration company needed was a "certify with the totalweight of the car", and "gas volym on the tank, liters". The foglight was also on wrong side, but i didnt need any so now i have just taken out the foglight bulb.
He said that the certify should come from the car company(impossible) or a known source, but he said that i could email what i could find, so does anyone have a site for the totalweight and petroltank liters?

According to the buying guide at the top of the forum the total weight is 1,150 kilograms and I believe the fuel tank is 56 litres.
I can't help much with the fan but they might not be working due to the connector terminals to the fans themselves. These are not waterproof and therefore can corrode.
Sorry can't be of more help. You could try calling Jason at TVR specialist Str8six; a very helpful chap.

The fans works when i plugged out the connector that does goes to the car that does steer the kick in at 95 degrees, now they are going all the time instead, better then that they are not going at all.
Okay thanks for the facts, about the weight i think i need the maximum load with the car weight, it means with people and gear, max load.

The first thing to check to make the fans work correctly is the coolant sensor. There are two, screwed into the block under the air box (you will have to remove the air box to get at them). One of for the dash temperature reading and one is for the ECU, which switches the fans.
These parts, like all others are best obtained from a TVR specialist to be sure you get the right part for your car. www.tvrpower.co.uk is a good place to start - they will take an order over the phone and they will be able to advise which is the correct part for your car.
Also, the brown box you refer to is known as a relay. It sounds like your car is over fuelling.

hi Targarama, thanks for the respons.
I have unplugged the one that goes to the ecu so the fans is going all the time now instead, havent driven much afterwards. But do you think i only need a new connection, it has maybe oxidized.
About the fuel, it is the brown relay im talking about, i get to much gas, after i have pumped out the gas with the relay out and are able to start again with relay in, the idle is very low and instable and the engine will die some times if you dont rev it to 1500.
When i checked the engine with the ecu program, the dash and the ECU program on the computer did show different water temp showings, the difference was 10 degrees, so one of the water temperatur sensors is showing the wrong temperature, i will check it later, but it shouldnt affect the fuel so much?
The engine has just been serviced with everything including tappet and camshaft.

MJ - I suggest you call the garage who serviced it for advice, it sounds like something is not right in the tuning department.
btw, there is often is discrepancy between the coolant temperature readings, it may not be a problem as long as the fans kick in/out when they should (one fan around 89-91 deg and the second around 93 deg on the ECU sensor).

I Have just had a similar problem with mine, The cause of your car not starting after the fans failed to kick in as mine did was the ecu not enabling the engine to run due to temp reading of 100 degrees as mine indicated on the dash? it cranked & fired but would not start & the fuel pumps still dumps fuel in the engine, once temp dropped to 95 it started okay, But rather worrying for me!!! all this happened in the rain with mine,
The cause of my fans not working was dodgy earth connection on chasis,
Check that fan 1 comes on at 90-91 degrees this will indicate that sensor to ecu ok,
Fan 2 kicks in 94-95 degrees , check fan connections & earth connections too,
Hope this puts some light on your problem & good look.

Im thinking on buying a universal temp sensor and replaced the other on the engineblock and calibrate the new sensor to kick in the fans at like 90 degrees. So then the ecu will not steered it, it will always kick in at the degree that the new sensor is set at. What do you think about that?
Sounds like a good idea, but i would find out for definate what caused your faliure?
I am considering manual switch & indicator running lights for the fans as i am planning to race mine next year, and want to eliminate any problems with the fans not kicking in,
New sensors calibrated can be a good thing to do,

Okay, the fans works now when i have unplugged the connection to the ecu under the airbox. So now i have the fans going all the time, then it should not be the connection on the fans that is failing?
Do you think it is the temp sensor that is not working, then is it this one i should order? http://www.tvrpower.co.uk/store/slug/coolant-tempe...
