Hi,

I've recently been taking my car for spirited runs through the hills now that everything seems to be working great. But the other night i noticed after giving it a bit of stick, it likes to get hot.

Normally my temperature sits about half, but it went up to around the 3/4 mark, so i backed off and drove calmly for a while, hoping it would go down, but it took another 5mins for it go down.

Im just wondering if this is normal because im driving hard and have a fmic in front, or if theres something not quite right, like a blocked radiator or faulty thermostat ?

Cheers

funny you say that, because my trays are not in place... I though this might have some to do with it, but never thought i would affect it that much.

Yep blocked radiator.
Take it out and take it to get flushed.

Usually one of the tanks is blocked or cracked.

Is there anyway to test that Gary ? Like would a section be alot colder than its supposed to be ? How much would a typical rad clean set me back ?

I got mine completely reconditioned (cleaned inside and out, fins straightened, new header tank etc) for a couple of hundred bucks at NATRAD or ADRAD.

Ok, I think i've found the problem.

The water pump seal at the front near the pulley looks to have broken. Its sprayed a fine layer of coolant around the engine bay, which is white, probably the reason i didn't pick it up earlier

Where is the cheapest to order a new pump, or if the seal can be redone, where should i look ?

Oh yeah they do that, Its a warning to CHANGE IT NOW!
But to be honest pull the radiator out anyway and get it flushed and checked. Its important.

Its not expensive.

You'll have to pull the radiator out to do the water pump anyway.
There's a link to a great tutorial in the tutorials section (100K service). Not too difficult a job.

Do the timing belt at the same time unless you've done it in the last 20000km.
