Overheating!!!!

[Dan_20vt]

Help!!!

On my journey to work today my temp gauge went up to 120 and the alarm sounded and light flashed. I pulled over onto the hard shoulder and checked for water etc and all seamed ok.

I then ran the engine for a bit and for some strange reason the engine temp returned to the normal 90'ish position within a couple of mins.

As I was only a couple of miles from work I decided to continue at low speed on the hard-shoulder. The temp moved around a little and again returned to 120 for a min so I knocked it out of gear and free wheeled and again the temp went to to just above 90.

I had been caught in the traffic for a little while (M20 is shite every day!) so I would expect the temp to rise a little but I've never had a problem before in two years.

Does this sound like a knackered thermostat, fan switch etc or do you think it might be something a little more serious?

Any comments would be appreciated.

Waterpump, known problem is your car under warranty?

 

[Dan_20vt]

No, are they easy to do or is it a stealer job?

 

[honeyman]

Doesn't have to be a stealer, also if you get it done ask for a brass impeller (i didn't have a choice) as the problem is that the plastic impeller slips or breaks, that how it's fine on tickover but soon as you increase the revs feck all happens, cause nothing is being pumped round the system. it's also worth getting your cambelt done at the same time.

oh joy, just spent £300 on service etc, then £300 getting remote locking working again and now £200-400'ish on getting this sorted!!!!

 

[honeyman]

Depending on who you use it may not be that bad as I believe it's no more than a couple of hours work and the pumps about £30 pounds max.

There seems to be a lot of cooling related problems....

John L there is a subtle difference between the two issues and Dan 20t's issues are classic water pump expiry, with the water pump gone driving up to 60mph ish is fine (temps stay around normal) but I guess when the turbo starts heating things up the gauge shoots up to 120degC and the red light comes on.

Dan get the work done ASAP as the pump is only partly broken but a fully expired pump could be thousands.

From memory my car was circa £250 with new cambelt and pump etc (probably 4 hours of labour alone at £40-£45)

Thanks for all your replies.

I was toying with getting the cam-belt done anyway, so I guess I should get it booked in today and talk the Mrs into letting me use her 1.4 Clio for a few days

I will make sure I ask for the brass impellor rather than the plastic one.

You could buy the part yourself, sure these people did one with a metal impeller, web site isn't brilliant but I gave them a call and they were great

Defo water pump. I got mine from here last time and although the one pictured is plastic, they send you the brass type as it states on the page.

SEAT Maidstone want £350 in all but can only supply/fit a plastic pump!

 

[claudefrog]

buy the pump.. take it elsewhere and ask them to fit it, also get timing belt kit done at same time

Having the same problem, but cambelt was changed 1 month ago.
I reckon I just have to change the water pump, right ?

unfortunately it is getting common!!! dont let the car heat up to much, you will end up with more problems.
My replacement part came from IMG Seat and it was metal....

 

[Degudodger]

I had exactly the same thing happen to mine last year. £300 for new Cambelt, tensioner and waterpump, which is about average.

Thank You

Just want to thank you all for your spot-on diagnosis.

As warned the impellor was split right through the middle!

I've now got my first engine upgrade

water pump is a cam belt service item now.
just done one on a mk4 golf...
it was running fine, but when removed the plastic impellor was cracked in 2 places just not slipped "yet"

German & Swedish brass impellor pump replaced it.

The cam belt has to come off to change the pump, and we all know the potential for damage when belts are removed / replaced...

At the very least, I would be considering replacing the cam belt tensioner, but then that's the most expensive of the parts, so you could change the belt again to be on the safe side...
