Overheating?

Recommended Posts

Thanks for the awesome advice. I made the graph. It took 8 minutes to get from 9 C to 80 C and then just hovered around 77 to 80. The oem temp gauge sits on about 90% at 80c. I just checked it after a freeway run, and it was still at 80C.

It looks like I sorted the overheating. I was watching for bubbles. There were no continuous bubbles but maybe 3 'burbs'  over ten minutes. Hopefully that's not a bad sign. 

Years ago when sky blue Datsun stanzas were uncool for a 20 YO, I paid a mechanic a weeks wages to find a non exisitant overheating problem. After he'd replaced everything, and the gauge still read high, he said the gauge must be faulty. Grrr.

Years back I was driving my girlfriend’s ( now Mrs Parrot) mk1 Escort back from Torquay late at night when the oil light came on outside Werribee, a sleepy country town in those days. 

No rattles, plenty of oil on the dipstick. Drove into Werribee and found a servo. 

Servos carried spare parts in those days, including Escort oil pressure sensors. And a man would put the petrol in your car for you!  Swapped it out, and all was well. 

7/11’s were just coming in then, and not surprisingly shut at 11!  Those were the days.

I think we all have one of those stories.

Mrs Banjo had an RA40 Celica, when I met her, & we once drove it to South Australia from Brisbane. The RA40 had an electric oil guage, so the sender unit down near the oil filter was quite large, compared to the simple oil warning switch.

Anyway, somewhere, a long way between towns all of a sudden the oil pressure guage needle drops to zero.  I think a guage displaying zero is somehow, an even more frightening visual, than a simple red light.  ( It sort of droops !)  Anyways, we stop, & check out everything.  Oil OK;  no sound of bearing rattles; fuses OK; short sender wire to chassis & oil pressure guage moves rapidly upwards.  So it appears in is just a sender unit, that has given up the ghost, at the most inconvenient of times. 

Next town is Mildura, about 40 minutes away. I ring Toyota dealer, not expecting them to have the part, but lo & behold, they had one in stock, but closed on Saturdays at midday, & it was nearly 11:30am, Saturday.  That was a very quick trip to town, especially, for future mother-in-law, who was in the back seat.  I figured 30 minutes of discontent was a better option than the remainder of the trip to Adelaide.

Happy ending !  Got there with 60 seconds to spare. Got the sender unit. Drove to the banks of the mighty Murray River, and fitted the new send. Drove to Adelaide, without further stress to future Mother-In-Law, & all ended happily. 

Cheers Banjo

Later on we had broken up. Then someone crashed into it as she went through an intersection. 

Her girlfriend calls me to console her and we got back together.  Meanwhile the car gets towed away to a crash repair place where the insurance wrote it off. Last we heard, the repairer bought it off her to become the works loan car.   Maybe he knew something and has a warehouse full of cars destined to explode in value. 

I hated the bloody thing

Bloody hell Pete !   You should put this story down, & get it printed in a paperback.  It would become a best seller.  I'm trying to think of a suitable title.

How about, the car telling the story.   How about  "My Life as an Escort" .  That should get an initial kick off in sales.

Actually, talking about paperbacks; I was given a paperback 10 days ago, called The Cockoo's Egg, which is a true story by Clifford Stoll.

The paperback was first published in the late 1980s, & recounts how the initial hacking of computers took place in the USA, and how they detected it. Sounds boring I know, but the writing style, & true substance was intriguing, and I couldn't put the book down for about 5-6 hours.  Unbelievably good read.

Cheers Banjo

Oh lordy. Its been a while since i price checked the escorts but they have jumped even more. My mates older brother bought a brand new black rs2000 turbo one of 200 i think. It was scary fast and he would drive it on the limit all the time. If it still exists it would be worth some bucks now.

Hey all, love the read and info flowing in this thread! But I have a situation of my own that's starting to rattle my brain. 

Recently bought into the rolla game, having found myself a beautiful old ke55 in very good condition, inside and out. 

Having now owned it for a few month and been tinkering around doing bits and pieces, I've come across bit of a pickle. Was trying to get the temp gauge working again (never worked when I bought it) I was replacing the sender to only crack the upper housing! (Think it had a hairline fracture in it or I might of over tightened just) it had a 5k thermostat housings used on a 4k engine and no thermostat in it. I'd made friend that had been playing around and working on rollas most of his life and luckily enough had spare lower and upper housing for a the thermostat and restored it back to the 4k thermo housing aswel. So I replaced the temp sender, installed a new thermostat (tested thermostat and it opens) wacked it all together and slapped it on the car. Reconnected one of the temp gauge wire (had 2 sender's and wires on the 5k housing, not exactly sure why) and started her up. 

Crappy enough, she worked but didn't stop till it reach hot on the gauge. Did the old put hand on radiator cap to see if it was actually running hot, and nup. Warmed the hand but no scalding. 

So with a new sender, thermostat 82deg to suit (that opens aswel) and the rad not actually getting hot. I'm kind of lost. 

There is one more thing I am going to try to be safe and pull the sender out and dip it into a cup of hot water, roughly heated to 85deg and see if the gauge goes all the way up. But that about the last thing I can think of. 

Any other ideas before I install a new vdo gauge? 

Oh, and I'm try to keep the car original as possible, with only fair light mods. So would prefer complete working dash. 

Many Thanks

Buy a 110deg thermometer and stick it in the radiator.  Cover the front of the rad & let the motor idle from cold to hot and check the gauge against the thermometer.

At least you'll know what temp the gauge marks mean.

Your sender may not be compatible with the gauge, or the gauge might be crook.  I found the 4AGE gave incorrect (well, different to the 4K) readings on the KE70 dash, but now I know what temp the marks are at.  A mate blew the head gasket in his Maxima because at boiling the gauge only read 'half'....

Thanks for the feedback altezza,

Yeah I'll do that and get a good idea of wear it sits. Might even invest in a infrared thermometer for future ordeals. 

Yeah, that's what I'm trying to avoid. Even tho 4k aren't the worst to deal with (rebuild wise) I still want to avoid having to do that. Haha 

Possibly a resistor issue to the gauge aswel? Will run a few tests over the next few weeks, but start with getting the right temp reading. 

Thanks again for the help. Will be hanging around or creating a discussion in the future. 

Ever interested in the car I'm restoring, I have a page going for it on Instagram for people to follow or check out.
