Tiger getting hot

[cps13]

Hi all,

I have recently bought a Tiger with a 1.8 zetec (115) running zx6 carbs. It gets very hot whilst stationary. Within 5 minutes of being on you can feel the heat coming off from around a foot from then engine and the fan kicks in after about 30secs to a minute.

It currently doesn't have an IVA so I cannot test it properly. Is this anything to worry about or is it normal for these cars?

My initial thought is that the carb setup isn't quite right.

Cheers,

I found my Pinto engined Tiger got pretty hot pretty quickly in traffic etc. I put it down to the small capacity of the cooling system - Polo radiator cooling a tuned 2.0 Pinto...

Given the lack of space for a larger radiator, I added an oil cooler which helped keep things under control.

If it is heating up very quickly - I guess you'll have checked the thermostat's not stuck closed, water pump doing it's job, any airlocks in the coolent circuit etc?

Carb set up, mixture worth checking, also check the timing as if that is out you can see things getting hot.

Hope that helps...

Before you spend money on a new radiator or oil cooler it may be worth checking the cooling system is working properly.

Is it really getting too hot? Modern engines run quite hot.
Is the fan blowing/pulling the right way?
Is the thermostat opening? Is it the correct one?
Does the rad get hot all over?
Is it plumbed correctly?
Is the water pump being driven in the right direction? (you would be surprised!)

The fueling/timing could also be out causing it to run hot.

A Polo radiator should be up to the job.

The man is talking logic.
I had a similar problem on my Quantum 2+2 RSturbo and I had made the mistake of swopping the wires roound on the cooling fan............its makes a huge difference.

On the zetec did you change the water pump for the one that goes the right way when you remove the power steering and ac pump? I also had my fan pushing rather than pulling, easy mistake.

I just added a secondary fan to my Quantum, similar problems, turbo engine, not much space for heat to dissipate when stationary, and relying on the thermostatic switch wasnt great. I've also added an Airtec alloy rad as well, and put the main fan as a blower and the secondary as a sucker to move some air around

You can get a lower temp thermostat on the Zetec, and a lower temp fan switch but if it's heat buildup regardless, moving the air around is going to be a better option

I didn't install the motor. Do you know the part number for the pump of which you speak?

Slightly off topic, if I wanted to chage my fan from blow to suck is it a simple case of swapping the wires over ?

With most fans no. It would work, but not properly due to the shape of the blades. Some you can turn the blades around, most not.

Not sure about the part number but you need the one off an early escort 1.6/1.8 for a car without ac iirc. Retro ford stock them amongst others.

Talk to Tiger about the pump.
They do a simple bracket and idler pulley that bolts onto the engine to re-route the drive belt so the existing pump can be used.

Can anyone look at the images below and see if they think the pump is going the right way.

We can't see the pictures. The belt should go drivers side (left) of the pump pulley looking from the front. If it goes passenger side (right) the pump will run backwards and can cause problems.


ETA: I can see them now. Yours is a different set up to mine. I'm sure others can confirm if yours is correct for than Pump arrangement.

Is the outlet from the pump straight or angled, I think you need the straight one. Also are there any part number on the pump, if there are stick them on here and we can wee if it is the correct one.

Only if the OP is running a 'Silvertop' Zetec E. The latter 'blacktop' engine doesn't have a suitable reverse direction pump AFAIK, so it has to be done by using an idler pulley to route the belt correctly.
