right i have a wierd problem, just had the engine rebuilt, and now when the car is on, the heat dial goes up almost instantly... cheked the pipes and the mechanics say its all the right temerature so the car isnt actully overheating, just the dial is playing up (was working perfetly before rebuild).

theyve changed the thermostat.. nothing

now they are changing the coolant sensor or something and checking the wiring back to the sensor but i dont think its that... any one had a problem like this?

any ideas? cheers all!

as per other post,your mechanic sucks
check the connection to the sender on the head,prob sender fucked

Sender fucked or the wrong combination sender/gauge.

(replaced sender or gauge unit in the rebuild?)

Deffo the sender! had this on one of my old cars!

coolio im going to tell them again what the problem is. i swear ive told them more from the information im getting from you guys than they know! im thinking i could have rebuilt the engine myself/ as in all they did was use the haynes manual to dissasemble the engine and send off the bottom end to get done. I COULD HAVE DONE THAT! im down Ł1200 and 2 months. supose i do get a nice piecce of paper prooving a rebuild for the next guy!

thanks all! if any other thoughts on what the heat problem could be, lemi know!

Id say it's the sender unless they've had the clocks out.

Whay did your Ł1200 get you

a full rebiuld top and bottom pretty much everything from followers to pistons and crank, new clutch and brakes+pads. and a nice spray on engine bay. and a guarantee.

clocks havnt been out. im hoping its the sender. where can i find this? what does it look like?

T28 RST

That sounds liek a bargain

A full engine rebuild plus

Cam
Followers
Pistons
Crank
Clutch

Discs
Pads

And a full respray of the engine bay.

I think you got a bargain there

havv

really?? thats a 1st. people are saying theyve rebuilt their cars for Ł200!!

to be honest though, even though this is a 'proper' garage, i want to see the car running properly on the road before i say anything more! will keep all posted. car will prbably be up for sale, so look out for an ad!

not with a new crank and pistons they didnt new pistons alone would cost that!!!

They've probably put a Series 1 sender in there, when mine was changed a Series 1 sender was put in and the temp guage shot into the red as soon as the ignition was on.

update.. so they changed the coolant sender, nothing. they found a leak in the rad, which is buggered, but they cant seem to get a match! :S theyve chekd a rs rad and a 1.3 rad, but doesnt fit. anyone know of any rads which might fit s2 1989?

I expect the wire is damaged somewhere and its shorting to earth, a dead short to earth puts the needle in the red.

DanRSturbo, i know there is a lot of controversy over these temperature senders, but my old Mk1 Orion had a S2 engine in it and the gauge always worked fine, and now i think of it im sure my current Mk1 has a later sender in it because the connector has been changed for a blue crimp which is the bullet style (mk3 senders are spade end)

I'd say its a short personally
