Hi all,
Long time reader, first time poster. I swapped my God awful Subaru Justy for a 1991 Sportrak 1.6 last week.
I've now been driving it for a few days and a couple of things bother me.
Firstly the temp gauge usually hovers between cold or a little bit up. Yesterday it went almost to half way after a relatively long journey.
Now, to go along with this, the radiator always SEEMS to be empty yet when I put more anti-freeze in the expansion tank over flows with hot water. There is no leak.
I also get a screeching noise when I first accelerate away when left standing and a clunk when coming off a kerb or turning the wheel full lock.
I thought the temp/radiator thing could be the thermostat and/or the fact that I've never had a Dihatsu before and so do not know if the radiator should show full when it is full.
The screeching noise...altenator belt/fan belt?
As for the clunk, I've heard you guys speak about it coming from the steering wheel...this isn't the case, it seems to come from behind the front wheels.
Any advice apprechiated

New Fortrak, a couple of niggles
Hi
Welcome to the Sportrak and the few niggles you have.
Lets take the easiest which is the noise on the steering. It is caused but the steering stops and can be cured by a large dab of grease on each. You will see the culprit if you put it onfull lock and have a look underneath.
The screeching noise is the fan belt and is very common. It is either loose of has been contaminated by oil and slipping. You ewill find it kick in worse with the lights on at night and although quite awkward to getto you need to loosten the Alternatorand retenson the belt. Replaement means removing the Powersteering belt first and I ways remOve the rad and cowl, make the task easier.
The water temperature ca be caused by a number of problems, a blown cylinder head gasket, leacking Radiator or a knackered water pumpor a knackered Rad cap. Rad caps reduce boiling point by keeping the system pressurised. When the engine is at normal working temp the hoses should be hard idicating that the system is pressurised. If soft then it is possible that the cap is in need of replacement and the water is steaming off. Normally under most situations the Sportrack temperature guage sits to the left of normal.
You say that the temp hovers below normal but went to normal yesterday after a long run. The Rad had lost water and boiling water was going into the header tank. I would therefore go for the cheap option of renewing the cap first particularily because of the boiling water going to the header tank. Once this is full it will go down the overflow. As I mentioned without the pressure effect of the system the water will boil off. As the water cools it will draw some back but because alot will have boiled off the rad will remain short of water. The water level is usually at the bottom of the neck. Have a look at the rubber seal on the cap, as a temp measure with care you can remove and turn over the seal or you can assist the seal with a piece of polythene. If the system is then pressurised then replace the cap asap.
Do you have water contamination in the oil? If so then it is most likely the cylinder head gasket has blown and allowing superheated exhaust gases into the water system.
Check also the fins at the bottom of the Raditor. These break away with age and reduce the cooling effect of the radiator.
There is also a possibility of an airlock in the system where it has been drained and not bled . I have to admit that I have drained mine many times and never had this problem but I am aware that others on this forum have found this to be a problem. To bleed remove the heater returnpipe and rn the engine till water comes through. The heater must be on to open the valve allowing the wter to pass thrugh the heater matrix. Once bled replace the hose and top up the rad.
Go for the cheap & simple options first and do not assume cylinder head failure unless you are haing water contamination of the oil, white sludge. Your symptoms make me believe that the cap is the problem.
You may also need toconsider replacement of the Cambelt unless you have proof ofit being done. They should be changed every 60000 miles or 6 years. If unsure ten get it replaced.
I hope this is helpfull
Good luck and enjoy the Sportrak, they are great and I have run a 1991 since 1995 and put over 100k miles on it. It is still superb and has cost very little to repair over those years, a new clutch, rad and rear spring and shocks,cam belts is about the lot except tyres and servicing. I have a stainless exhaust from Ribble Bros which has been on since 1996 and still going strong. I also have a 1996 Anjou which is not as good in build quality to the older car but just as reliable.

Wow, thanks very much for
Wow, thanks very much for your reply. I've had a few different cars in my time and of course subscribed to forums about them online but never had so much help! I seem to be in love with the Sportrak...I've had a Vitara before but never did I check it over every few days or hose underneith it as often or just go and sit in it lol!
When I first got the car I was driving back from picking it up and the suddenly there was a grinding noise and I veered left when breaking. Turned out the brake caliper bolt had not been tight and pinged out. So I got that replaced and (it only having an MOT done in August) did some digging through old receipts and MOTs. Turned out that the car MOT'd at 25k in 2006, 86k in August this year and now (1 month later ish) reads 32k...something dodgy going on! However, the cambelt cover states the belt was changed at 25k so I assume that's last year and someone has just badly clocked the car.
Anyhow...today I took the car for its furthest journey yet and the temp went up to normal and then beyond it to about a quarter before the highest. I took a look in the radiator and it looked pretty empty although the expansion tank was only about 3 quarters full. Luckily I have no sludge under the oil cap, no white smoke from back when optimal running temp, no CO2 smell under the oil cap...so generally no head gasket type signs.
I had replaced the radiator cap on Friday and there definately is pressure under it. I think my next step is to flush the system and refill with anti-freeze and also check the fins at the bottom and the radiator.
I'll keep you posted
Cheers

Look at oldminimans reply, ensure the heater valve is open as the symptoms you describe typify the heater matrix not being full.
Many people do not open the heater valve when draining and refilling the cooling system, when the engine is run, a quantity of water fills it, this removes water from the cooling system, and fills the heater matrix. Dropping the water level means the temperature sensor is not immersed in water, but in an air lock in the cylinder head, this then measures the temperature of the metal cylinder head, or air temperature, not water temperature.
As the water expands, this refills the head to a certain degree, water may be over a small part of the temperature sensor causing it to rise, as it is too a degree, measuring the now elevated water temperature.
When refilling the cooling system, raise the front of the vehicle, slowly fill with a watering can, and allow the water time to settle, and any air to rise to the top of the cooling system, i.e. the now highest point, the radiator filler.
ok...well opened up the rad
ok...well opened up the rad cap yesterday, put the heaters on hot and open full and let the car run. Now, I know I was meant to open the radiator plug at the bottom as well but after several attempts I couldn't get to it
After a while of it running (and squeezing the pipes) I turned it all off.
Now, I went out in it twice yesterday and both times it eventually went to normal on the gauge...infact on the second trip to went from normal to quarter and back to normal...but didn't go over and try and over heat.
The noise with the steering is gone with a little grease and a little more power steering fluid and yes the squeeking does get worse when the lights are on...so I assume fan belt...which I will get tightend/replaced on Friday.
Dihatsu Drivers Club has fixed it for me?
