Hilux Surf

[debfay]

Hi ya. We have a hilux surf 1988, turbo. We travel with the air-con on and go up a hill and we loose power and temp gauge goes into the red, only does this when air-con is on. Temp goes back down when you go along the flat. Only started doing this 1yr ago.

We have had the following done: radiator, hoses,thermostat,temp sensor,pressure test-hot and cold,added an extra fan on the front.

Have had it to 2 diesel blokes without success. Use to get 400 to 450 ks now only get 350 ks.

think thats about it.

thanks

Hi ya Debbie.

 

Sorry to say it but you'll have to get use to it. It's also the same when you tow a trailer.

Whats the belts like ? And the water pump ?

You could try with getting a radiator shop to flush the system.

Your best bet would most likely be a bigger radiator.

Urm, with the fuel try cleaning the injectors, new fuel filter and maybe even get the pump serviced.

 

You might have better on http://www.toyotasurf.asn.au/ but at the moment its saying that the site exceeded its bandwidth.

Or http://www.outerlimits4x4.com/index.php Something to note is that outerlimits have changed servers so any of the links you'll have to take out the " /PHP_Modules " bit first till things get sorted out

We had the same problem in our suzuki a few years.

 

There was a switch just for the fan and a switch for the A/C fan. we unpluged the A/C pump on really long trips or when towing. so when ya flick the A/C on just the A/C fan will come on not the pump and hey presto it didnt over heat anymore. :) :)

Surfs are renowned for overheating problems. Have a search on the ExplorOz website/forum and you'll find heaps of discussions about it. Many people believe that since Surfs are grey imports and were never intended to be sold in Australia, they are not built for Australian conditions. I haven't read too much into the issue but it doesn't seem like there is an easy fix to the problem. Maybe a radiator upgrade? ExplorOz would be the place to ask, and the question has probably already been answered on there so have a search.

 

My advice would be to trade it in for a 4runner since Toyota actually built them with the intention of selling them here and they are a much more reliable vehicle. No turbo diesel though, unfortunately, but the 2.8 diesel is the original unbreakable one and is efficient. It will dead-set go forever. The V6 is thirsty but has lots of go. Older models had the 2.4 diesel which is also very reliable.

The 2.4 and 2.8 diesels are very reliable as long as their not in a surf. From what i've heard is that for some reason the heads crack in the surfs but not any other vehicle (eg. hilux).

So swap the motor from a hilux into a surf then?

I think the problem is more to do with the surf cooling system/radiator etc. Like I said, check out exploroz, there'll be heaps of info. Even the Fishnet 4x4 forum might have some useful stuff.

BHG?

would explain overheating underload and loss of economy....

maybe just a small leak....

[dysolve]

remember boys a girls we talking about a diesel here... not like petrol..

The bad new maybe that you had a blocked radiator/cooling system, and when it overheated the first time it damaged the internals of the engine, now that you have fixed the radiator the same "simtum's" ( i can't speeeel) but the cause is different. If this is the case and its had to check, the engine is almost dead.. If it is dead DO NOT get it rebuilt, contact and engine importer and get your self an import 3.0L TDI. A diesel rebuild will cost you at least $6000 but an import should cost around $3000.. The difference in fuel usage could be due to two things.. stuff injector pump if the car has more then 150000k'm on it and the pump has not been done then theres your problem ($1500 to get pump rebuilt) or the engine damage is stuffing it all up.. I have found my hilux "eats" fuel when its hot outside..

 

Diesels do not like being "cooked" even once is to much. It could be lots more things e.g block oil lines, damaged turbo.. and the list keeps going..

 

and as far as I know the Hilux/4runner and suft motors are all the same L,2L,2L-T,3L,3L-T AND SO ON..

hrmm, don't diesels have headgaskets?

the motors may be the same, but the bays and the air flow isnt going to be....

[dysolve]

yes they do have head gaskets. They could have a look at it. But once a diesel has been cooked they are normally stuffed.. because of the amount of heat made by the compression and so on, over heating a diesel is not good. In the workshop manuals I have the only time there are airflow differences is when the engine was forced induction. And what do you mean by bays? The only time I have seen a small Toyota diesel with head gasket problems we could not even start it. If i remember correctly it had compression problems due to the gasket being stuffed. But I suppose I am not a diesel mechanic and every thing I know is out of personal experience, and anything could really be the problem.

Mmm diesel..... i'm starting to have a preference for the stuff. Maybe a hilux but not a surf because they run hotter then a 'lux because the surf wasn't built for aussie conditions

 

and as far as I know the Hilux/4runner and suft motors are all the same L,2L,2L-T,3L,3L-T AND SO ON..

Hilux, 4runner (and surf), tarago, cressida, hiace...... have the same motor. And the only one that runs hot is the surf.

Its a strange strange phenomenon :jamie:
